For most of human history there was little to no economic growth. Until the nineteenth century, the average person everywhere in the world lived at a subsistence level. For example, although the Roman Empire controlled most of Southern and Western Europe, the Near East, and North Africa for more than 400 years, the living standard of the average citizen of the Empire was no higher at the end of the Empire than it had been at the beginning.

Economists typically measure economic growth by the rate of increase in real GDP per capita. The following figure, updated from Chapter 11 of Macroeconomics (Chapter 21 of Economics), shows the slow pace of growth in real GDP per capita in the world economy from the year 1 to the year 1820 and the much faster rates of growth over the following periods. As discussed in Chapter 11, the figure relies on data compiled by Angus Maddison of University of Groningen in the Netherlands and—for recent years—data from the World Bank.

This year’s three Nobelists have contributed to understanding why economic growth accelerated sharply in the nineteenth century and why England was the first country to experienced sustained increases in real GDP per capita—an event labeled the Industrial Revolution. Joel Mokyr of Northwestern University has conducted decades of research into which innovations were crucial to economic growth and the institutional and economic advantages that allowed entrepreneurs in England to use those innovations to expand production much more rapidly than had happened before. Philippe Aghion of Collège de France and INSEAD and Peter Howitt of Brown University have focused on formally modeling the process of creative destruction that underlies sustained economic growth. The classic discussion of creative destruction appears in Joseph Schumpeter’s book Capitalism, Socialism, and Democracy, published in 1942.

In Macroeconomics Chapter 21, we discuss the process of creative destruction in the context of economic growth. Creative destruction occurs as technological change results in new products that drive firms producing older products out of business. Examples are automobiles driving out of business producers of horse-drawn carriages in the early twentieth century. Or Netflix and other movie streaming sites driving video rental stores out of business in more recent years.

The Nobel Committee’s announcement of the prize can be found here. A longer discussion of the Nobelists’ work can be found here. The scope of their research can be seen by reviewing their curricula vitae, which can be found here, here, and here. The amount of the prize this years is 11 million Swedish kronor (about $1.2 million). Mokyr receives half and Aghion and Howitt receive the other half.

Acemoglu, Johnson, and Robinson Win the 2024 Nobel Prize in Economics

Many economic studies have a relatively limited objective. For instance, estimating the price elasticity of demand for soda in order to determine the incidence of a soda tax. Or estimating a Keynesian fiscal policy multiplier in order to determine the effects of a change in federal spending or taxes. (We consider the first topic in Microeconomics, Chapter 6, and the second topic in Macroeconomics, Chapter 16.)

Other economic studies consider much broader questions, such as why are some countries rich and other countries poor? As the late Nobel laureate Robert Lucas once wrote: “The consequences for human welfare involved in questions like these are simply staggering: Once one starts to think about them, it is hard to think about anything else.”

Today, the Royal Swedish Academy of Sciences awarded the 2024 Nobel Prize in Economic Sciences to Daron Acemoglu and Simon Johnson of MIT, and to James Robinson of the University of Chicago for “for studies of how institutions are formed and affect prosperity.” Acemoglu, Johnson, and Robinson (AJR) have published work highlighting the key importance of a country’s institutions in explaining whether the country has experienced sustained economic growth. Their work builds on earlier studies by the late Douglas North of Washington University in St. Louis, who received the Nobel Prize in 1993.

The institutional approach to economic growth differs from other approaches that focus on variables such as temperature, prevalence of disease, ethnic fragmentation, resource endowments, or governments adopting flawed development strategies in explaining differences in growth rates in per capita income across countries.

Two of AJR’s most discussed papers are “The Colonial Origins of Comparative Development: An Empirical Investigation,” which was published in the American Economic Review in 2001 (free download here), “Reversal of Fortune: Geography and Institutions in the Making of the Modern World Income Distribution,” which was published in the Quarterly Journal of Economics in 2002 (available here). In these papers, the authors argue that the institutions European countries established in their colonies helped determine economic growth in those countries even decades after colonization.

As with any analysis that covers many countries over long periods of time, AJR’s analysis of the effect of colonialism on economic growth has attracted critiques focused on whether the authors have gathered data properly and whether their data may be better explained with a different approach.

The authors, writing both separately and jointly, have explored many issues beyond the effects of colonialism on economic growth. The wide scope of their research can be seen by reviewing their curricula vitae, which can be found here, here, and here. The announcement by the Nobel committee can be found here.

Claudia Goldin Wins the Nobel Prize in Economics

Claudia Goldin, the Henry Lee Professor of Economics at Harvard, has been awarded the 2023 Nobel Prize in Economic Sciences. Goldin’s research is wide-ranging, with a focus on the economic history of women and on gender disparities in wages and employment. She received her PhD from the University of Chicago in 1972 for a thesis that was published in 1976 as Urban Slavery in the American South, 1820 to 1860: A Quantitative History. Her thesis adviser, Robert Fogel, was awarded the Nobel Prize in 1993 for his work in economic history. He shared the prize that year with Douglas North of Washington University in St. Louis. Goldin’s work on economic history contributed to the cliometric revolution, which involves the application of theoretical models and econometric methods to the study of historical issues.  At the time of the award to Fogel and North, Goldin discussed their research and the cliometric revolution here.

Goldin’s pioneering and influential research on the economic history of women was the basis for her 1990 book Understanding the Gender Gap: An Economic History of American Women. The themes of that book were expanded on in 2021 in Career & Family: Women’s Century-Long Journey toward Equity, and in her forthcoming An Evolving Force: A History of Women in the Economy.

In research with Lawrence Katz, also a professor of economics at Harvard, Goldin has explored how technological change and educational attainment have affected income inequality, particularly the wage premium skilled workers receive. Goldin and Katz summarized their findings in 2008 in the influential book, The Race between Education and Technology.

The wide scope of Goldin’s research can be seen by reviewing her curriculum vitae, which can be found here. The announcement by the Nobel committee can be found here.
