The Nobel Prize in Economics has been awarded to Turkish-American economist Daron Acemoglu and British-American economists Simon Johnson and James Robinson for their groundbreaking research on wealth inequality between nations. Their work provides crucial insights into the relationship between political and economic institutions and how these structures shape the prosperity of countries. This research has deepened our understanding of why some countries succeed economically while others remain trapped in poverty, despite globalization and developmental efforts.

The Central Focus: Institutions and Wealth Inequality

Acemoglu, Johnson, and Robinson’s research primarily examines the political and economic systems introduced by European colonisers and how these systems have long-lasting effects on the development of various nations. The Royal Swedish Academy of Sciences, which awarded the prize, emphasised that their work highlights the vital role of societal institutions in determining economic success.

Their research shows that "inclusive institutions"—political systems that ensure equal rights and provide individuals with the opportunity to influence governance and pursue their economic ambitions—are critical for fostering long-term economic growth. In contrast, "extractive institutions"—where power is concentrated in the hands of a few, and wealth is extracted from the majority—lead to stagnation and inequality.

Nogales: A Case Study of Divided Economies

One of the key examples cited by the Nobel committee is the city of Nogales, which straddles the U.S.-Mexico border. Residents on the northern (U.S.) side enjoy greater economic prosperity and political freedoms, while those on the southern (Mexican) side face economic hardship and fewer opportunities. According to the laureates, this disparity is not due to geographical or cultural differences but rather the contrasting political and economic institutions on either side of the border. The U.S. system provides its residents with better opportunities for education and economic mobility, alongside broader political rights that allow citizens to influence legislation. In contrast, the system in Mexico restricts such rights, leading to slower economic growth and fewer opportunities for advancement.

This example illustrates the profound impact institutions can have on wealth distribution and economic outcomes. The laureates argue that institutions, not geography or culture, are the decisive factors behind why some nations prosper and others do not.

The Democratization Effect

One of the significant contributions of Acemoglu and his colleagues is their focus on how the democratization of political systems can lead to economic growth. According to Acemoglu, countries that transition from non-democratic to democratic regimes tend to experience faster economic growth. This growth is primarily because democracies tend to implement inclusive institutions that provide equal opportunities for citizens, fostering innovation and allowing the economy to expand. In contrast, authoritarian regimes often maintain extractive institutions that limit opportunities and concentrate wealth and power among the elites, preventing equitable growth.

The Broader Impact on Economic Thought

Acemoglu, Johnson, and Robinson’s research goes beyond explaining why countries experience different levels of economic growth. Their work has also helped explain why some nations become trapped in "low-growth" scenarios, where economic progress is stifled by persistent inequality and entrenched political power. In this sense, their findings have practical implications for policymakers worldwide, offering a framework for promoting more equitable growth by fostering inclusive institutions.

The Nobel committee’s recognition of their work underscores the importance of political and economic structures in shaping the fortunes of nations. By focusing on institutional differences, they have provided a new lens through which economists and policymakers can address the vast income disparities between nations.

Legacy of the Laureates

Daron Acemoglu, Simon Johnson, and James Robinson have significantly influenced global discussions on inequality and development. Acemoglu, in particular, has authored several best-selling books, including Why Nations Fail: The Origins of Power, Prosperity, and Poverty, which explores the ideas central to their Nobel-winning research. Their work is also timely, as global inequality continues to be a pressing issue, with many countries struggling to close the economic gap despite overall global wealth growth.
