Robert Lucas Jr.: the story on HearLore

Robert Emerson Lucas Jr. was born on the 15th of September 1937 in Yakima, Washington. His parents ran an ice creamery there before it failed during the Great Depression. The family moved to Seattle after the business collapsed. His mother worked as a fashion designer while his father took jobs at a shipbuilding yard and later as a welder with a refrigeration company. He received his Bachelor of Arts degree in history from the University of Chicago in 1959. This background seemed unrelated to economics until he changed course. He attended the University of California, Berkeley as a first-year graduate student but left due to financial reasons. He returned to Chicago in 1960 to earn a PhD in economics by 1964. His dissertation focused on substitution between labor and capital in U.S. manufacturing from 1929 to 1958. He studied economics for his doctorate on quasi-Marxist grounds because he believed economics drove history.

John Muth published Rational Expectations and the Theory of Price Movements in Econometrica volume 29 pages 315 to 335 in 1961. Lucas incorporated this idea into dynamic macroeconomic models in 1972. Agents in his model are rational based on available information. They form expectations about future prices and quantities using that data. These agents act to maximize their expected lifetime utility according to the theory. Federal Reserve Bank of Minneapolis noted in 2022 that work launching the revolution still resonates today. He provided sound theoretical foundations for Milton Friedman and Edmund Phelps regarding long-run neutrality of money. The correlation between output and inflation appeared in the Phillips curve during that era. This empirical relationship did not yield a possibility of policy trade-offs despite appearances. The hypothesis transformed how economists analyze macroeconomic systems globally.

Lucas challenged the foundations of macroeconomic theory in 1976 when Keynesian approaches dominated the field. He argued that macroeconomic models should be built as aggregated versions of microeconomic models. Aggregation in the theoretical sense may not be possible within a given model according to his analysis. Relationships appearing in the economy could change in response to changes in economic policy. This formulation became known as the Lucas critique of economic policymaking. It influenced the development of new classical macroeconomics significantly. The drive toward microeconomic foundations for macroeconomic theory gained momentum from this argument. Inflation and unemployment relationships shifted when policies changed. The reformulation reshaped how policymakers understood economic interactions across decades.

Hirofumi Uzawa collaborated with Lucas on the Uzawa, Lucas model of human capital accumulation. They developed a theory suggesting people can be tricked by unsystematic monetary policy. The Lucas paradox considers why more capital does not flow from developed countries to developing countries. Lucas published a seminal contribution in economic development and growth literature in 1988. Paul Romer worked alongside Lucas to herald the birth of endogenous growth theory. Research on economic growth resurged during the late 1980s and the 1990s thanks to their work. Lucas contributed foundational ideas to behavioral economics regarding investor irrationality. Deviations from the law of one price found intellectual foundation in these contributions. He stated in 2003 that depression prevention had been solved for all practical purposes five years before the Great Recession. The Lucas Wedge shows how much higher GDP would be with proper policy implementation.

The Nobel Memorial Prize in Economic Sciences was awarded to Lucas in 1995. The citation noted he developed and applied the hypothesis of rational expectations. This achievement transformed macroeconomic analysis and deepened understanding of economic policy. N. Gregory Mankiw characterized him as the most influential macroeconomist of the last quarter of the 20th century. In 2020, he ranked as the 10th most cited economist in the world. He was elected to the American Academy of Arts and Sciences in 1980. A Guggenheim Fellowship followed in 1981 along with election to the National Academy of Sciences. The American Philosophical Society elected him in 1997. A collection of his papers is housed at the Rubenstein Library at Duke University. His prize lecture on Monetary Neutrality occurred on the 7th of December 1995.

Lucas married an undergraduate classmate from the University of Chicago named Rita Cohen. The couple had two sons including Stephen born in 1960 and Joseph born in 1966. They divorced during the 1980s after raising their children together. The divorce stipulation included a clause entitling Cohen to half of his Nobel prize winnings if awarded before the 31st of October 1995. This deadline ended up being met when the prize arrived that year. After divorcing Cohen, Lucas married Nancy Stokey who collaborated on growth theory papers. Their joint work covered public finance and monetary theory topics extensively. Lucas died in Chicago on the 15th of May 2023 at age 85. He left behind a legacy spanning decades of economic research and teaching.
