Exploring the Roots of Economic Inequality: Nobel Laureates’ Groundbreaking Research

On 14 October 2024, the Nobel Prize in Economics was awarded to three American professors—Simon Johnson, Daron Acemoglu, and James A. Robinson—for their comprehensive research into how institutional structures shape the prosperity or decline of nations. The laureates provided a crucial link between economic growth and the rule of law, arguing that societies lacking strong legal frameworks and inclusive institutions struggle to foster development and meaningful change.

The Central Argument: Institutions Matter

The trio’s research, grounded in historical analysis, focuses on the divergent paths taken by different nations following European colonialism from the 16th century onwards. Their findings underscore the importance of institutional quality in determining the economic fate of countries. The study reveals that societies with exploitative institutions are less likely to experience long-term economic growth, while nations with inclusive political and economic systems are more likely to thrive.

Their research draws on the history of colonisation, demonstrating how the institutions established during colonial rule have had a lasting impact on the economic development of various regions. According to their findings, societies where colonisers created inclusive institutions to benefit settlers tended to flourish. In contrast, regions where colonisers established extractive institutions—designed to exploit local populations and resources—have remained economically disadvantaged.

The Importance of the Rule of Law

The laureates’ work highlights the crucial role that the rule of law plays in fostering economic growth. In societies where the rule of law is weak, corrupt institutions often exploit the population, leading to stagnation and economic decline. By contrast, societies with strong legal systems and institutions that prioritise the welfare of the broader population tend to experience sustained economic growth.

This framework explains why some nations are rich while others remain poor, despite having similar geographic or resource-based advantages. The researchers argue that the differences in wealth and development can often be traced back to the types of institutions established during colonisation.

The Impact of European Colonisation

Johnson, Acemoglu, and Robinson’s research draws a direct line between the mortality rates of European settlers and the types of institutions they established in various colonies. In regions where settler mortality was high, such as parts of Africa and India, European colonisers tended to create extractive institutions that exploited local labour and resources. These institutions, which were designed to benefit a small elite rather than the broader population, have persisted in many cases, leading to economic underdevelopment and inequality.

By contrast, in regions where settler mortality was lower, such as Australia and New Zealand, European colonisers were more likely to establish inclusive institutions that encouraged investment and long-term growth. These regions, now among the wealthiest in the world, continue to benefit from the inclusive systems created by European settlers.

The Persistence of Economic Inequality

One of the key insights from the laureates’ research is the persistence of economic inequality between nations. Despite significant economic growth in many developing countries, the income gap between the richest and poorest nations remains vast. According to the researchers, the wealthiest 20% of countries are approximately 30 times richer than the poorest 20%. Moreover, while poorer nations have seen some economic improvement, they are not catching up to the wealthiest nations.

This inequality is not merely a product of geography or resources but is rooted in the institutional frameworks that govern these nations. The researchers point out that the differences in colonial institutions have created a lasting legacy, which continues to shape the economic fortunes of nations today.

The Role of Democracy in Economic Growth

Another significant aspect of the laureates’ research is the role of democracy in promoting economic growth. According to Acemoglu, democratising countries tend to experience faster economic growth than those with authoritarian regimes. On average, countries that transition from authoritarianism to democracy experience approximately eight to nine years of accelerated economic growth.

However, the researchers caution that democracy is not a panacea. While democratisation can help spur economic growth, it is not guaranteed to solve all of a country’s problems. Inclusive political and economic institutions are essential for ensuring that the benefits of democracy are felt by the broader population, rather than being concentrated in the hands of a few.

The Colonial Legacy: Institutions and Economic Divergence

A key contribution of the laureates’ work is their explanation of how different colonial strategies led to divergent economic outcomes. In densely populated regions with significant resistance from local populations, European colonisers were more likely to establish extractive institutions. These institutions, designed to benefit the colonial elite, have had a lasting impact on the economies of these regions, many of which remain among the poorest in the world today.

By contrast, in sparsely populated regions with less resistance, European settlers were more likely to establish inclusive institutions that promoted economic growth. These regions, which include countries like the United States, Canada, Australia, and New Zealand, continue to benefit from the strong institutions established during the colonial period.

Institutions Shape Economic Outcomes

The research of Johnson, Acemoglu, and Robinson provides a powerful explanation for the enduring economic inequality between nations. Their work highlights the importance of strong, inclusive institutions in promoting economic growth and shows the lasting impact of colonialism on the development of modern economies.

By linking economic outcomes to the quality of institutions, the laureates have provided a framework for understanding why some nations succeed while others struggle to overcome poverty and inequality.
