An examination of the global problems that no single government can solve alone — and the governance arrangements, tradeoffs, and contested obligations that shape how the world responds
In the summer of 2010, a heat wave settled over Russia's wheat-growing regions with extraordinary force. Fires burned across millions of acres of farmland. The harvest collapsed. Within weeks, the Russian government banned grain exports. Within months, the price of wheat on global commodity markets had risen sharply. Bread prices climbed in Egypt, Algeria, Tunisia, and across the Middle East and North Africa — regions that import heavily from Russia and Ukraine. Historians and political scientists who later studied the Arab Spring uprisings of 2011 noted that food price spikes were not the cause of those political convulsions, but they contributed to the economic grievances that brought millions of people into the streets. A weather event in Russia, mediated through global commodity markets, contributed to political instability thousands of miles away in countries that had no influence over Russian agricultural policy, global market prices, or the atmospheric conditions that produced the drought.
This is what global interdependence looks like in practice. The problems that sovereign states face in the twenty-first century do not respect borders. A virus that emerges in one country can spread to every continent within weeks through international air travel. Carbon dioxide emitted by power plants and automobiles anywhere on Earth accumulates in a shared atmosphere and contributes to a warming that affects every society. A financial crisis in one country's banking system can ripple through interconnected global markets and throw millions of workers in other countries out of jobs. Migrants and refugees displaced by conflict, poverty, or environmental deterioration move across borders whether or not the destination countries wish to receive them. Digital networks that allow instant communication across the world also create pathways for cybercrime, disinformation, and surveillance that no single government can fully control.
These global problems share a common structural feature: they require collective action among sovereign states that are formally independent, often have conflicting interests, and lack any superior authority capable of compelling them to cooperate. This is the central challenge of global governance examined throughout Part VIII of this textbook, and it is the specific focus of this chapter. Chapter 44 explained the institutions — the United Nations, regional organizations, international financial institutions, trade bodies, and human rights mechanisms — through which international cooperation is organized. This chapter examines the substance: the specific global problems that test those institutions, and the particular challenges each problem poses for international cooperation.
The problems examined in this chapter — trade and economic interdependence, migration and refugees, climate change, pandemic disease, global inequality and development, and technology governance — are not merely interesting international relations topics. They are among the central political questions of the contemporary world. They appear constantly in domestic political debates. They shape elections. They influence the daily lives of ordinary people in every country. They produce intense disagreements about fairness, responsibility, national sovereignty, and global justice. A student who understands these problems — what they are, why they are hard to solve, what approaches have been tried, and what tradeoffs different approaches involve — is a more informed citizen and a more capable participant in the political conversations of this era.
Students who complete this chapter will understand why global problems are hard to solve, how international cooperation works and fails in practice, and how the choices that governments and citizens make about these problems shape the lives of people around the world. They will also be prepared to think seriously about what obligations, if any, people living in one country have to people living in others — one of the deepest and most enduring questions in the study of politics and government.
A factory in one country emits carbon dioxide that contributes to climate change affecting farmers in a distant country. A pharmaceutical company in a wealthy nation holds patents on a vaccine that could save lives in a poor one. A refugee fleeing war arrives at the border of a country that did not cause the conflict. In each case, ask: Who is responsible? Who has obligations to whom? What institutions exist to manage these situations — and are they adequate? By the end of this chapter, you will have the conceptual tools to analyze each of these scenarios with care and precision.
The following terms will be defined and explained in this chapter. Pay attention to each term as it appears.
The international system is built around sovereign states, each formally independent and responsible for governing its own territory. Yet the problems that states must manage increasingly ignore the boundaries between them. What distinguishes genuinely global problems from ordinary domestic ones is a combination of two features: the causes and effects of the problem cross borders in ways that make purely national solutions insufficient, and the problem involves shared resources or systems so that what one country does affects what happens to others.
The clearest examples involve what economists call externalities — costs or benefits that the actions of one party impose on others who have no say in those actions. When a factory emits carbon dioxide, the warming it contributes to is felt everywhere on Earth. When a traveler unknowingly carries a novel pathogen across international borders, the health consequences fall on people in the destination country who had no say in whether the flight should have departed. When a country devalues its currency to gain a trade advantage, it imposes costs on trading partners. These cross-border externalities are the structural reason why global problems require international cooperation rather than purely domestic policy.
Many global problems also involve what are called global commons — resources or systems that belong to no single state but upon which all states depend. The atmosphere that regulates Earth's climate is a global commons. The high seas beyond national jurisdictions are a global commons. The radio frequency spectrum is a shared resource whose use must be coordinated internationally to prevent interference. The internet's foundational infrastructure rests on shared protocols and standards. When global commons are used without coordination, they tend to be degraded — a phenomenon that ecologist Garrett Hardin called the "tragedy of the commons." International governance attempts to manage global commons in ways that prevent this degradation.
The fundamental challenge of global governance is what political scientists call the collective action problem: a situation in which everyone would benefit from cooperation, but each party has individual incentives to avoid bearing the costs of cooperation while hoping others will bear them instead. This dynamic — sometimes called the free rider problem — is especially severe at the international level because no authority can compel states to cooperate. Consider climate change. Every country would benefit from a stable climate. But stabilizing the climate requires dramatically reducing global greenhouse gas emissions, which involves real costs. Each country has an incentive to reduce its own emissions as little as possible while hoping other countries bear the larger burden. If enough countries reason this way, emissions are not reduced sufficiently even though all countries would benefit from a stable climate.
Several features make global collective action problems particularly severe. Costs and benefits are distributed unevenly — wealthy industrialized countries have emitted far more carbon dioxide historically than developing countries, but all countries bear costs from climate change. The time horizons of global problems often extend far beyond electoral cycles — the benefits of climate action accrue over decades while costs are borne now. And many global problems involve scientific complexity and uncertainty that makes building political consensus difficult even when the underlying analysis is robust.
One specific form of collective action problem that recurs across global issues is the race to the bottom. If countries compete to attract investment or export industries, and if one form of competition involves lowering environmental standards, labor protections, or tax rates, competitive pressure can drive all countries to reduce standards even when all would prefer a world in which high standards were maintained everywhere. International agreements that set minimum floors on standards attempt to prevent race-to-the-bottom dynamics by removing the competitive advantage of lowering standards. These agreements are themselves politically contested because they constrain national policy choices and raise questions about the proper scope of international authority.
International institutions, agreements, and norms are the primary tools available for addressing global collective action problems. These tools include binding treaties that create legal obligations, monitoring and verification mechanisms that make compliance observable, enforcement mechanisms that impose costs on defectors, financial transfers that compensate countries for bearing greater burdens, and norm-building processes that shift what states consider acceptable behavior. No single approach works for all global problems. Binding treaties with strong enforcement mechanisms work best when the problem is well-defined, the parties are few, compliance can be monitored, and the costs and benefits of cooperation are roughly symmetrical. The Montreal Protocol on ozone-depleting substances — which successfully phased out chlorofluorocarbons — is often cited as a model. Many of the problems discussed in this chapter are harder: more parties, more complex causal pathways, larger economic stakes, and more contested distributions of costs and benefits.
The free rider problem describes a situation in which individuals or states benefit from a collective good without contributing to its provision, leaving others to bear disproportionate costs. In international politics, free riding is a persistent challenge because global public goods — a stable climate, a disease-free world, safe seas — are available to all countries regardless of whether they contribute to producing them. A country that refuses to reduce its greenhouse gas emissions still benefits if other countries successfully stabilize the climate. The free rider problem is one of the central reasons why international cooperation on global problems is difficult even when all parties agree, in principle, on the value of the cooperative outcome. Solving it typically requires monitoring, enforcement, and mechanisms that make defection costly.
International trade has grown dramatically over the postwar period, driven by declining transport costs, liberalization of trade rules, improvements in communication technology, and deliberate policy choices by governments. The value of global merchandise exports grew from roughly fifty billion dollars in 1948 to more than twenty-five trillion dollars in the early 2020s. Supply chains — the networks of suppliers, manufacturers, and distributors that produce finished goods — have become genuinely global, with components crossing multiple borders before assembly and sale.
This integration has created profound economic interdependence. The United States imports large shares of its consumer electronics, clothing, and pharmaceuticals. China imports iron ore, petroleum, and agricultural commodities. Germany exports machinery and automobiles bought throughout the world. Virtually every advanced economy is deeply integrated into global supply chains for goods considered essential — including, as the COVID-19 pandemic demonstrated, medical supplies and pharmaceuticals.
Economic interdependence creates mutual benefits and mutual vulnerabilities simultaneously. The mutual benefits are well established: trade allows countries to specialize in goods and services they produce relatively efficiently, expands consumer choice, reduces prices, and creates competitive pressures that can drive innovation. The mutual vulnerabilities became visible in crises. When global shipping networks were disrupted in 2021, shortages of consumer goods and industrial components rippled through economies worldwide. When semiconductor shortages emerged, automobile manufacturers, electronics companies, and defense contractors discovered how deeply dependent they had become on a small number of fabrication facilities concentrated in a few East Asian locations.
As Chapter 44 explained, the World Trade Organization provides the primary framework of multilateral rules for international trade, based on principles of non-discrimination, tariff binding, and dispute settlement. But alongside the multilateral WTO framework, a dense network of bilateral and regional free trade agreements has developed — more than three hundred as of the early 2020s. This proliferation has created overlapping and sometimes inconsistent rules that create compliance burdens for businesses and undermine the coherence of the multilateral system.
The relationship between trade and development is actively debated. The dominant view among economists held that trade liberalization was broadly beneficial for development. Some countries — particularly in East Asia — achieved rapid development while maintaining significant protection for certain domestic industries during critical periods of industrialization, suggesting the relationship is more complex. A further complication involves agricultural trade: many wealthy countries maintain substantial subsidies for their farmers, depressing global agricultural prices and making it harder for developing-country farmers to compete. This pattern has been a persistent source of tension in WTO negotiations.
The COVID-19 pandemic prompted intense debate about the vulnerabilities of global supply chains. Shortages of personal protective equipment, pharmaceutical ingredients, and semiconductors revealed how deeply dependent wealthy countries had become on a small number of foreign suppliers. Governments in the United States, the European Union, Japan, and elsewhere enacted policies to subsidize domestic semiconductor production, pharmaceutical manufacturing, and other strategic industries — policies in tension with WTO free trade principles. Whether these policies represent genuine national security needs, justified responses to market failures, or disguised protectionism that benefits domestic producers at consumers' expense is contested.
International trade generates domestic political tensions because it produces winners and losers within countries even when it increases overall national income. A worker who loses their job because their employer moved production abroad does not benefit directly from the lower consumer prices that trade creates. Studies of labor markets found that workers and communities exposed to intense import competition suffered significant and persistent earnings losses. The political effects were substantial: communities that experienced the largest negative effects of trade showed larger swings toward anti-establishment political candidates. This political dynamic illustrates a fundamental challenge in global governance: even when international cooperation produces aggregate gains, its distributional consequences can generate political opposition that undermines the cooperative arrangements themselves.
When one WTO member believes another has violated trade rules, it can bring a complaint through the following stages:
The system's effectiveness depends on parties' willingness to comply with rulings. The blockage of the Appellate Body by the United States beginning in 2017 — which by 2019 left it unable to function for lack of a quorum — created significant uncertainty about the dispute settlement mechanism. Despite this limitation, the WTO dispute settlement system remains the most developed of its kind in international trade governance, and its procedural record over three decades illustrates both the promise and the limits of rules-based international cooperation.
By the early 2020s, approximately 280 million people — more than three percent of the world's population — lived outside their country of birth. This includes economic migrants seeking better employment and living standards, refugees fleeing persecution and conflict, asylum seekers awaiting status determination, and millions of irregular migrants who cross borders without legal authorization. International movement at this scale is not a new phenomenon, but its political salience has intensified in democratic societies across the wealthy world.
The causes of international migration are complex and interconnected. Economic disparities between countries create powerful incentives to move from lower-income to higher-income areas. Conflict and political repression displace people from their homes. Environmental degradation and increasingly severe climate-related disasters make some areas progressively less habitable. Family reunification motivates millions of legal immigrants. Demographic differences — aging populations in wealthy countries needing workers, young populations in developing countries — create structural pressures for migration that persist regardless of policy choices in destination countries.
A refugee is a person who has fled their country of origin and cannot return because of a well-founded fear of persecution based on race, religion, nationality, political opinion, or membership in a particular social group. This definition comes from the 1951 Refugee Convention, the foundational document of international refugee law, supplemented by the 1967 Protocol that removed the Convention's original geographic and temporal limitations. The UNHCR registers refugees, provides assistance, advocates for durable solutions — voluntary repatriation, local integration, or resettlement — and monitors states' compliance with their obligations.
The Refugee Convention establishes the principle of non-refoulement — the obligation of states not to return refugees to territories where they face persecution. This is the cornerstone of international refugee law: whatever a state's immigration preferences, it cannot forcibly return someone to a place where they face a serious risk of persecution or torture. Non-refoulement is recognized in customary international law and is binding on all states, even those that have not formally ratified the Refugee Convention. As of the early 2020s, the world's forcibly displaced population exceeded 100 million people — including recognized refugees, internally displaced persons, and millions of asylum seekers. The countries hosting the largest numbers are typically developing countries neighboring conflict zones, not the wealthy countries that are most prominent in political debates about migration.
An asylum seeker is someone who has applied for refugee status but whose claim has not yet been determined. Asylum seekers are entitled to have their claims assessed fairly, but do not have a right to a positive determination. The processing of asylum claims has become highly politicized in many wealthy countries, with large backlogs, measures to deter arrivals, and intense debate about the balance between legal protection obligations and border management preferences.
Economic migrants — people who move primarily for better employment or living standards — are not covered by the refugee regime and their migration is governed by destination countries' domestic immigration laws, which vary enormously. The mismatch between economic demand for migrant labor and restrictive legal immigration pathways creates conditions for large-scale irregular migration, with dangerous journeys undertaken by people who cannot access legal routes. The governance of international migration is fragmented. Unlike trade, there is no multilateral framework of binding rules governing migration. The 2018 Global Compact for Safe, Orderly and Regular Migration established principles and objectives but was explicitly non-binding.
Remittances — money sent home by migrants — are a major income source for many developing countries, in some cases exceeding foreign aid flows. But migration creates a brain drain problem when the most educated and skilled people leave developing countries. Countries that train doctors, engineers, and teachers at public expense may see them emigrate to wealthy countries where their skills are better rewarded — a particularly acute problem in health care, where some developing countries face critical shortages while significant numbers of their medical graduates practice abroad. Managing this tension between the rights and opportunities of individual migrants and the needs of their origin communities is a genuine governance challenge with no easy resolution.
The European Union has developed a regional framework — the Common European Asylum System (CEAS) — that attempts to harmonize asylum procedures and reception conditions across member states. The Dublin Regulation generally assigns responsibility for examining a claim to the EU state through which an asylum seeker first entered. This creates severe burdens for frontline states — Greece, Italy, Spain — while reducing pressure on interior states. The CEAS has been under significant stress during periods of large-scale arrivals, revealing deep disagreements among EU member states about burden-sharing, reception standards, and the pace of procedures. Reform of Dublin rules has been among the most contested issues in EU politics for a decade, illustrating how deeply migration can divide regional integration projects.
North American approaches are primarily bilateral and national rather than regional. The United States and Canada have a Safe Third Country Agreement under which asylum seekers must generally apply in the first country they arrive in. The United States maintains a separate refugee resettlement program through which it selects refugees from overseas, distinct from the domestic asylum process — with the number of resettlement slots varying dramatically across administrations, reflecting deep partisan disagreement.
Both systems illustrate the tension between protection obligations under international law and domestic political pressures to limit arrivals. Neither has found a stable resolution to the tension between the legal duty of non-refoulement, practical limits of state capacity to process and integrate large numbers, and the political contestation surrounding migration policy in democratic societies. What they share is the challenge of governing migration in ways that are simultaneously legally compliant, practically manageable, and politically sustainable.
Climate change refers to long-term shifts in global temperatures and weather patterns driven primarily by the accumulation of greenhouse gases — principally carbon dioxide and methane — in Earth's atmosphere. The scientific evidence for human-caused climate change is overwhelming: global average temperatures have risen approximately 1.1 to 1.2 degrees Celsius above pre-industrial levels since the late nineteenth century, producing rising sea levels, increased frequency and intensity of extreme weather events, shifts in precipitation patterns, melting glaciers, ocean acidification, and changes in ecosystems that affect food security, water availability, and human health.
Climate change represents one of the most severe collective action problems in international relations. The causes are effectively universal — greenhouse gas emissions occur in every country with significant economic activity — but deeply unequal. Wealthy industrialized countries have contributed the majority of cumulative historical emissions. The impacts fall disproportionately on countries and populations that have contributed least — low-lying island states facing inundation, Saharan countries facing intensified drought, coastal communities in South Asia vulnerable to storms and sea-level rise. This asymmetry between responsibility and vulnerability is the central political challenge of international climate negotiations.
International climate governance has developed through a series of agreements under the United Nations Framework Convention on Climate Change (UNFCCC), adopted at the Rio Earth Summit in 1992. The UNFCCC established the principle of "common but differentiated responsibilities and respective capabilities" (CBDR-RC) — the idea that all countries share responsibility for addressing climate change but that their specific obligations should reflect their historical contributions and capacity to act. The Kyoto Protocol (1997) was the first binding international climate agreement, establishing quantified emissions reduction targets for developed countries. The United States signed but never ratified; Canada later withdrew; major developing economies including China and India were excluded from binding targets. Its practical impact was limited.
The Paris Agreement (2015) adopted a fundamentally different architecture. Rather than imposing binding emissions targets, it required each country to submit its own Nationally Determined Contribution (NDC) — a climate plan describing what the country would do. NDCs are not legally binding in their substance; countries set their own ambition levels. What is binding is the requirement to submit NDCs, have them reviewed, and update them with progressively greater ambition over time. The Paris Agreement established shared temperature goals — well below 2°C of warming, with an aspiration to limit warming to 1.5°C — and included provisions on adaptation, finance, and technology. Its near-universal participation (195 parties) came at the cost of binding ambition: analysis consistently finds that even full implementation of current NDCs would result in warming of 2.5 to 3 degrees or more.
Climate finance refers to financial flows directed toward low-carbon investments and climate adaptation in developing countries. At the Copenhagen conference in 2009, wealthy countries pledged to mobilize 100 billion dollars per year by 2020 for developing countries — a pledge not fully met on schedule, and contested in its accounting. The debate over climate finance involves not just amounts but form: grants versus loans, public versus private, new money versus redirected existing aid. The most contentious emerging issue is loss and damage — compensation for climate-related harms that developing countries have already suffered as a result of historical emissions from wealthy countries. The 2022 COP27 agreed to establish a loss and damage fund, but the details of funding and governance remained contested. Technology transfer — sharing low-carbon technologies with developing countries on favorable terms — is another contested dimension, pitting intellectual property protections against the imperative of rapid global decarbonization.
Addressing climate change requires massive investment in low-carbon energy systems, adaptation, and compensation for losses. The costs are real and large. Who should bear them — and on what basis?
Wealthy industrialized countries have emitted the vast majority of the greenhouse gases causing current warming, so they bear primary moral responsibility. Developing countries that contributed little to the problem should not bear the costs of solving it. Wealthy countries should not only reduce their own emissions most aggressively but also provide generous financial and technological support so developing countries can achieve clean energy transitions without sacrificing economic development. Justice requires that those who caused the problem pay to fix it.
Effective climate action requires significant participation from all major current emitters, including China, India, and other large developing economies that now account for the majority of global annual emissions. Holding wealthy countries exclusively responsible is neither scientifically viable nor politically sustainable. Climate finance should be targeted to produce the greatest emissions reductions and adaptation benefits, not simply redistributed on historical grounds. The most important goal is achieving rapid global decarbonization as quickly as possible.
Some argue that the burden-sharing debate has distracted from the practical task of deploying clean energy at scale. Climate justice advocates argue that the most vulnerable people within both wealthy and developing countries should be centered in policy design, and that the interests of future generations must be weighed against those of the present.
Emphasizing historical responsibility strengthens moral claims but may deter current major emitters from accepting ambitious commitments. Emphasizing current capacity can motivate broader action but may be perceived as disregarding justice claims. Financial transfers can compensate for distributional inequities but may be insufficient in scale. The disagreement is partly about values and partly about what kinds of agreements are achievable.
A developing country argues that it has the right to pursue economic development using fossil fuels because wealthy countries did so during their industrialization. Evaluate this argument. What are its strongest points? What challenges does it face given the current state of scientific knowledge and the global atmosphere? What policy response, if any, does your analysis suggest?
A pathogen that emerges in one location can reach every major city on Earth within days through commercial aviation. The SARS outbreak of 2002–2003 spread from China to thirty-seven countries within months. The H1N1 influenza pandemic of 2009 circled the globe in weeks. The COVID-19 pandemic became a global crisis of unprecedented scope — infecting hundreds of millions, killing millions, collapsing health systems, devastating economies, and revealing profound weaknesses in both national health systems and international public health cooperation.
Pandemics represent a pure collective action problem. No country can fully protect itself without international cooperation, because disease does not respect borders. A country that invests heavily in pandemic preparedness cannot protect itself if neighboring countries have weak surveillance systems that allow diseases to circulate undetected. The benefits of preparedness are genuinely global, but the costs fall on individual national health budgets. Political systems with short electoral horizons tend to underinvest in risks that appear distant until they arrive suddenly and at overwhelming scale.
The primary framework for international public health governance is the International Health Regulations (IHR), a legally binding agreement significantly strengthened in 2005 following SARS. The IHR requires countries to develop core public health capacities, report potential public health emergencies promptly, and accept international assistance in responding to outbreaks. The World Health Organization is the UN specialized agency responsible for international public health. The WHO can declare a Public Health Emergency of International Concern (PHEIC) — the highest alert level — triggering specific obligations for information sharing and coordinated international response.
The WHO's authority is fundamentally limited by its dependence on member states for both funding and cooperation. Voluntary contributions from wealthy member states and private donors have grown to represent the majority of WHO funding, giving major donors disproportionate influence over priorities. If a country underreports an outbreak or delays notification, the WHO can express concern and apply diplomatic pressure — but it cannot independently verify the situation without the country's cooperation. This structural limitation became acutely visible during the COVID-19 pandemic's early months.
The COVID-19 pandemic provided the most demanding stress test of international public health cooperation in a generation. Areas of relative success included the rapid development of effective vaccines — accomplished in under a year through unprecedented public and private investment and international scientific collaboration — and the rapid sharing of the virus's genetic sequence by Chinese scientists, enabling global vaccine development to begin immediately. More significant failures were also evident. Many wealthy countries turned to nationalism in their pandemic responses — restricting exports of personal protective equipment, competing for vaccine doses, and prioritizing their own populations before sharing internationally. The COVAX mechanism — designed to ensure equitable vaccine access — was underfunded and outcompeted by wealthy countries that signed bilateral deals with manufacturers before COVAX could establish its supply. By mid-2021, wealthy countries were vaccinating rapidly while most low-income countries had received almost no doses.
This disparity was not merely unjust but epidemiologically counterproductive: as long as the virus circulated freely in unvaccinated populations, it continued to evolve and produce variants that could evade immunity in vaccinated populations elsewhere. The pandemic demonstrated, in real time, that the distinction between helping others and protecting oneself can break down in the face of an interconnected global pathogen. The pandemic prompted extensive debate about reforms: a new pandemic preparedness treaty with stronger obligations; increased and restructured WHO funding; stronger international surveillance mechanisms; and reformed intellectual property rules to enable faster scale-up of vaccine production in developing countries.
When a potentially significant disease event is identified, the WHO's Health Emergencies Programme activates assessment and response protocols. The organization's Event Management System tracks health events globally in real time. If a country reports a potential Public Health Emergency of International Concern, the WHO Director-General convenes an Emergency Committee of independent experts to assess whether the event meets PHEIC criteria. A PHEIC declaration signals that a serious public health risk requiring coordinated international response has been identified and triggers specific recommendations to member states.
During an outbreak, the WHO coordinates technical guidance, provides technical assistance to affected countries, manages pre-positioned supplies of medical countermeasures, coordinates international laboratory networks, and communicates risk information to the public and to member governments. What the WHO cannot do is equally important to understand: it cannot compel countries to share information, accept WHO technical missions, follow WHO guidance, or take specific public health measures. The WHO's authority is persuasive and coordinative, not coercive.
This structural limitation reflects a fundamental feature of international governance: member states created the WHO and fund it, but they retain sovereignty over their own health systems and their own compliance decisions. The result is an institution that is highly effective at convening expertise, setting standards, and coordinating voluntary action — and significantly limited in its ability to compel action when powerful member states prefer to act unilaterally or to obstruct international response. Understanding this gap between what the WHO is designed to do and what it can actually compel is essential for evaluating proposals to strengthen global pandemic governance.
Global economic inequality is profound. The wealthiest fifth of the world's population earns roughly sixty times as much as the poorest fifth. Life expectancy at birth ranges from over eighty years in high-income countries to under sixty years in some low-income countries. Child mortality rates in the poorest countries are more than twenty times higher than in the wealthiest. Access to education, financial services, clean energy, and digital technology is massively skewed toward wealthier populations. These are not merely statistical disparities; they represent dramatically different conditions of human life and human possibility.
This inequality has deep historical roots. The economic divergence between wealthy and poor countries accelerated during the colonial period, when European powers extracted resources, established exploitative trade relationships, and underinvested in the human and physical capital of colonized territories. Post-independence development paths varied enormously: some formerly colonized countries achieved remarkable economic progress, while others remained trapped in cycles of poverty, poor governance, conflict, and resource dependence. Global inequality has both moral dimensions — what obligations wealthy individuals and countries have toward the global poor — and political dimensions — whether and how reducing global inequality is achievable through international governance.
The primary mechanism through which wealthy countries transfer resources to developing countries is Official Development Assistance (ODA) — grants and concessional loans from wealthy governments and multilateral institutions. A long-standing international target calls on wealthy countries to devote 0.7 percent of their gross national income to ODA — first endorsed by the UN General Assembly in 1970. As of the early 2020s, only a handful of countries, primarily Scandinavian, consistently meet the target. ODA has been praised for specific achievements — the eradication of smallpox, dramatic reductions in child mortality from preventable diseases, increased school enrollment, infrastructure investment — and criticized for being poorly targeted, conditioned on recipients following donor-country policy preferences, and an inadequate substitute for more fundamental reforms in trade rules and global economic governance.
In 2015, the UN General Assembly adopted the Sustainable Development Goals (SDGs) — seventeen goals and 169 targets to be achieved by 2030, addressing poverty, hunger, health, education, gender equality, clean water, affordable energy, decent work, inequality, sustainable cities, climate, and other dimensions of human wellbeing. The SDGs are aspirational, not legally binding. Progress was mixed before the COVID-19 pandemic reversed progress on many dimensions, and projections suggest most SDG targets will not be met globally by 2030. The SDG framework has been valuable in creating shared metrics and political accountability for development outcomes, but it has not generated the resource flows or policy changes needed to achieve its goals.
External debt has been a persistent challenge for developing-country governments. Borrowing to finance development can be productive if borrowed resources support growth, but when growth fails to materialize or debt is denominated in foreign currencies that strengthen, countries can find themselves unable to service existing obligations without cutting public investment in health, education, and infrastructure. Debt relief initiatives — including the Heavily Indebted Poor Countries (HIPC) Initiative — provided significant reduction to dozens of countries and freed resources for public investment. The rise of China as a major development finance provider added complexity, funding significant infrastructure across Africa, Asia, and Latin America while also generating controversy about terms, transparency, and debt sustainability.
The governance challenges posed by digital technology differ from those in other areas examined in this chapter in several important respects. They are newer — governance frameworks are in their early stages. They move faster — the pace of technological change exceeds the pace at which governance institutions can adapt. They are more pervasive — digital technologies affect virtually every sector of the economy and touch the daily lives of billions. And they involve technical complexity that makes democratic deliberation challenging: it is difficult for elected officials, let alone ordinary citizens, to evaluate regulatory tradeoffs for technologies whose full implications are not yet understood even by experts.
The core technologies at issue include the internet and its fundamental infrastructure; platforms for social communication and commerce; algorithms that filter information and target content; artificial intelligence systems that can generate text, images, and code; vast stores of data these systems generate and depend upon; and critical infrastructure — power grids, financial systems, transportation, healthcare — that increasingly depends on digital control systems vulnerable to disruption.
The internet's fundamental infrastructure has historically been governed through a distinctive multi-stakeholder model including governments, private companies, technical bodies, civil society, and academic institutions. Bodies like ICANN, the Internet Engineering Task Force, and the World Wide Web Consortium set standards and manage core resources through processes involving technical experts rather than governments alone. This model has been contested from the beginning by governments — particularly authoritarian ones — that prefer intergovernmental control. The divergence between the open internet model and what some analysts call the "splinternet" — a fragmented network of nationally controlled internet environments — represents one of the most significant structural tensions in digital governance. China has constructed a heavily filtered, censored, and monitored national internet environment. Russia has enacted legislation enabling isolation of Russian internet infrastructure. The question of who governs the internet is increasingly consequential as governments assert greater national control.
Different countries have adopted radically different approaches to governing personal data. The European Union's General Data Protection Regulation (GDPR), enacted in 2018, establishes comprehensive rights for EU citizens over their personal data — access, correction, deletion, objection to automated decision-making — and imposes significant obligations on companies that collect and process data. The GDPR has become a de facto global standard for many companies operating internationally. The United States has taken a more sector-specific approach without a comprehensive federal data protection law. China has enacted data protection legislation but embeds it within a framework that also mandates data access by government and security agencies. Data sovereignty — where data must be stored, whether it can cross borders, what governments have authority over data about their citizens — is a rapidly developing and contested governance area.
Artificial intelligence has advanced rapidly, becoming one of the most consequential and contested technological developments of the early twenty-first century. AI systems are already making consequential decisions in credit scoring, hiring, medical diagnosis, criminal justice risk assessment, content moderation, and military targeting. Governing AI poses challenges that cut across every issue in this chapter: AI can generate disinformation at scale; military AI raises profound questions under international humanitarian law; AI systems trained on biased data can perpetuate discrimination; and AI capabilities could dramatically accelerate both beneficial and harmful technological capabilities. International governance of AI is in early stages. The OECD adopted AI Principles in 2019. The EU enacted its AI Act in 2024. Several bilateral and multilateral discussions about AI safety have been initiated. Comprehensive international governance frameworks do not yet exist, and developing them faces fundamental challenges of pace, diversity of national interests, and deep disagreements about appropriate regulation.
Cybersecurity has become a major national security concern and international governance challenge. Critical infrastructure — power grids, water systems, financial markets, transportation, healthcare — increasingly depends on digital systems that can be disrupted by cyberattacks. International norms for responsible state behavior in cyberspace are developing but contested. Major states conduct significant cyber operations against each other while publicly endorsing norms against such behavior. Attribution of cyberattacks is technically difficult, and enforcement is limited. The gap between the norms that states publicly support and their actual behavior in cyberspace is one of the more visible examples of how international governance can lag behind the actual practices of powerful actors.
Data sovereignty refers to the idea that data generated within a country's borders, or about a country's citizens, should be subject to that country's laws and governance. The concept has gained salience as governments recognize that data is a strategic economic and security resource, and that existing international arrangements allow large flows of data to be processed and stored outside national jurisdictions. Data sovereignty claims can protect privacy and national security, but they can also restrict the free flow of information, enable surveillance by authoritarian governments, and fragment international digital commerce. The appropriate balance between data sovereignty and open global data flows is a central contested question in technology governance — one that reflects deeper disagreements about the proper scope of state authority over digital life.
A consistent theme across the preceding sections of this chapter is the gap between the scale of global problems and the adequacy of existing governance arrangements. This gap is not accidental. It reflects structural features of the international system that make governing a deeply interdependent world through sovereign states fundamentally difficult.
The problem of variable geometry affects every global issue. Global problems involve different sets of countries in different ways — climate change is primarily a problem of major emitters and major victims; pandemic disease travels through highly connected countries; migration crises concentrate in particular origin and destination regions. Institutions designed for universal membership — the UNFCCC, the WTO, the IHR — often struggle to achieve the specific, coordinated commitments that effective action requires from key actors. Smaller clubs of key countries can sometimes act more quickly, but at the cost of legitimacy and universality.
The sovereignty paradox recurs across all areas of global governance. States need international cooperation to address global problems that domestic action cannot solve, but they resist the degree of sovereignty constraint that effective international governance requires. The result is often arrangements that are politically achievable — voluntary commitments, non-binding targets, frameworks that leave enforcement to states themselves — but insufficient to address the underlying problems. This paradox is not simply a failure of will; it reflects the genuine structural tension between the logic of national self-governance and the logic of global interdependence.
The representation and legitimacy challenge undermines political sustainability. The veto structure of the UN Security Council, the weighted voting of the IMF and World Bank, and the technical complexity of WTO dispute settlement all give disproportionate influence to wealthy and powerful states. Developing countries — often most vulnerable to global problems — frequently have the least influence over international arrangements that shape their situation. This representation deficit generates political opposition that can undermine international cooperation by reducing the domestic legitimacy of international commitments in the societies most affected.
Non-state actors play increasingly important roles in global governance. Multinational corporations — with revenues exceeding those of many nation-states — make decisions about investment, employment, and technology that profoundly affect people worldwide. Non-governmental organizations provide essential services in humanitarian crises, advocate for human rights and environmental protection, and mobilize global civil society. Philanthropic foundations provide significant funding for global health and development. The governance of non-state actors — their accountability, transparency, and the conditions under which they should influence international rules — is itself an unresolved governance challenge.
Perhaps the deepest question posed by global interdependence is a moral one: what obligations do people living in one country have toward people living in others? Do citizens of wealthy countries have obligations to open borders to migrants from poorer countries? Do industrialized countries have obligations to pay for climate adaptation in developing countries that contributed little to warming? Do wealthy countries have obligations to cancel debts, transfer technology, or open markets? These questions do not have universally agreed answers. Different traditions in political philosophy — cosmopolitanism, nationalism, contractarianism — give different answers about the scope and basis of obligations to distant others. Democratic political systems, which give power to citizens within national borders, tend to weight the interests of co-citizens more heavily than the interests of foreigners. Yet the fact that global interdependence means that choices made in one country affect people in other countries creates a structural argument for international accountability that goes beyond bare treaty obligations.
The challenges examined in this chapter are serious and existing governance arrangements are insufficient — but the history of international cooperation includes examples of governance arrangements that seemed impossible becoming standard over time. The Montreal Protocol, the World Trade Organization, the International Criminal Court, and the Global Fund to fight AIDS, tuberculosis, and malaria all represent institutional achievements that seemed unlikely before they were accomplished. Whether current and future generations can build similarly effective institutions for climate, pandemics, migration, and technology governance depends on political will, institutional innovation, and the democratic accountability of governments to citizens who understand what is at stake.
The United Nations Framework Convention on Climate Change (UNFCCC) was adopted at the Rio Earth Summit in June 1992 and entered into force in March 1994. It established the foundational framework for international climate cooperation and the Conference of the Parties (COP) process that has continued for more than three decades. It was adopted at a time of growing scientific consensus on climate change but before the full dimensions of the problem were understood, and established principles that continue to shape climate negotiations today.
The preamble acknowledges climate change and its adverse effects as "a common concern of humankind," noting that the largest share of historical and current global greenhouse gas emissions has originated in developed countries. Article 3 establishes five foundational principles: the parties should protect the climate system for present and future generations on the basis of equity and common but differentiated responsibilities; precaution should govern responses where scientific uncertainty exists; and sustainable development is affirmed as a right of all countries.
The UNFCCC's "common but differentiated responsibilities and respective capabilities" (CBDR-RC) principle captures a genuine moral and political tension at the center of international climate governance. It acknowledges that all countries share responsibility for addressing climate change while insisting that specific obligations must reflect historical contributions and capacity to act. This principle has been central to virtually every subsequent climate negotiation. It explains why developing countries have resisted binding emission reduction targets, and why wealthy countries have committed — imperfectly — to climate finance. The document also reveals how international agreements must simultaneously address the distribution of responsibility and the need for universal participation — a tension that no subsequent agreement has fully resolved.
A new international commission has been established to design a permanent global pandemic preparedness and response system following the COVID-19 pandemic. You are a member of the commission. Your mandate is to propose an institutional design that would provide more effective and equitable global pandemic governance than existing arrangements.
Citizens and governments of all countries; WHO and UN system; vaccine manufacturers, pharmaceutical companies, and biotechnology firms; health worker organizations; civil society and patient advocacy groups; international financial institutions; national public health agencies; low-income countries with weak health systems; high-income countries with advanced health infrastructure; future generations who will live with long-term consequences of today's governance choices.
Epidemiological analysis of transmission dynamics; assessments of preparedness capacity needs and costs; legal analysis of what new obligations states would accept; political analysis of major power interests; financial analysis of pandemic costs compared to preparedness investment; public health expert assessment of which governance architectures most effectively reduce future pandemic risk.
Design your proposed pandemic preparedness system. Which option or combination do you recommend? What would it cost, who would govern it, and what obligations would it impose? How would you ensure financial sustainability and political durability between crises? What tradeoffs are you accepting, and why do you believe your design is superior to alternatives?
International treaty — foundational document of international refugee law.
The 1951 Refugee Convention was adopted in the wake of World War II and the Holocaust, responding to the failure of states to protect those fleeing persecution in the 1930s. It was initially limited to European refugees displaced before January 1951. The 1967 Protocol removed these geographic and temporal limitations, making the Convention universal in scope. The Convention was the product of negotiation among states with different interests — some seeking protection obligations, others seeking limits on their commitments.
Article 1(A) defines a refugee as any person who, owing to a well-founded fear of persecution for reasons of race, religion, nationality, membership of a particular social group, or political opinion, is outside the country of their nationality and is unable or unwilling to avail themselves of the protection of that country. Article 33 provides that no contracting state shall expel or return a refugee in any manner whatsoever to the frontiers of territories where their life or freedom would be threatened on account of one of the Convention grounds.
Select one global problem: climate change and the Paris Agreement; the international refugee crisis and UNHCR; international trade governance and the WTO; global pandemic preparedness and the WHO; global inequality and the SDGs; or the governance of digital technology and AI.
Step 1 — Current scope: Establish the current scale and trajectory of the problem using the best available data — satellite measurements, UNHCR statistics, WTO dispute records, WHO surveillance data, or comparable sources.
Step 2 — Governance architecture: Map the international institutions, agreements, and key actors with authority over your chosen problem. What can each do? What can they not do?
Step 3 — Recent developments: Identify major recent events, negotiations, agreements, or crises (past three to five years) and analyze how they affected the governance landscape.
Step 4 — Strengths and limitations: Assess where existing governance is working and where it is failing, with structural explanations for both.
Step 5 — Reform assessment: Identify active reform proposals, their advocates, and the obstacles they face. Evaluate which reform you would prioritize and why.
Recommended sources: UN agency and treaty body websites, OECD and World Bank data, reporting from major international affairs outlets, academic journals and databases, and relevant think tank publications on international governance.
Chapter 45 concludes Part VIII, which has examined how states interact beyond their borders through diplomacy, international law, war and peace, international organizations, and the global problems that require collective action. Part IX turns to comparative government — the systematic study of how political systems differ across countries and what those differences mean for citizens, rights, representation, and policy. Chapter 46 introduces comparative government as a method: how to compare systems fairly using institutions, regime types, political culture, and policy outcomes. The analytical tools developed throughout this textbook — authority, legitimacy, representation, rights, institutions, and governance — come together in Part IX as you learn to apply them to the full diversity of political systems that exist in today's world.
The global problems examined in this chapter resist easy answers and quick solutions. They are hard because they involve genuine conflicts of interest among countries and populations that see the world from different vantage points, bear different responsibilities for global challenges, and face different vulnerabilities to their consequences. They are hard because they operate on timescales that do not align neatly with electoral cycles and political incentives. They are hard because the international system was designed for a world of sovereign states and has only partially adapted to a world of profound interdependence. And they are hard because addressing them requires asking difficult questions about obligation, fairness, and the proper scope of international authority — questions to which different political traditions and different empirical assessments give different answers.
Understanding these problems does not require treating all countries as equally responsible for global challenges to which they have contributed very differently. It does require taking seriously the fact that choices made in one country affect the lives of people in others — that emissions decisions affect distant coastal communities, that vaccine procurement decisions affect vaccination rates on other continents, that interest rate decisions affect developing-country debt levels. In an interdependent world, the ability to insulate oneself from these consequences is limited. A warming climate does not protect those who chose cleaner energy from the consequences of others' emissions. A virus that spreads in unvaccinated populations does not respect the borders of the vaccinated world.
The institutions examined across Chapters 41 through 45 — international organizations, regional bodies, trade frameworks, human rights systems, development institutions, and emerging governance arrangements for climate, pandemics, migration, and technology — are imperfect instruments. They reflect the political compromises of their founding moments, the power imbalances of the international system, and the limitations of institutions that must serve many masters simultaneously. They are not adequate to the scale of the problems they face. But they represent the accumulated effort of generations of diplomats, civil servants, lawyers, scientists, and citizens to build something more than a world of unconstrained power competition — to create, however imperfectly, a degree of order, predictability, and shared responsibility in international life.
The choices ahead about how to govern global problems are not technical choices for experts alone. They are political choices that involve fundamental questions about fairness, sovereignty, obligation, and the kind of world that current and future generations will inhabit. These choices will be made through the political processes of democratic societies — through elections, debates, legislation, and the exercise of citizenship. The students who engage seriously with the material in this chapter are preparing to participate in those choices more thoughtfully: understanding the stakes, recognizing the tradeoffs, evaluating competing arguments, and contributing to the democratic deliberation that shapes how governments and citizens respond to the challenges of an interconnected world.
