# Robert Lucas Jr.

> He rewired how economists think about expectations — the idea that people aren't blindly backward-looking but adjust their behavior based on what policy will likely do next. That shift, called rational expectations, made him the most influential macroeconomist of the late 20th century.

## Bio

Robert Emerson Lucas Jr. was born September 15, 1937, and spent his career at the University of Chicago. He became the central figure in new classical macroeconomics by developing and applying the hypothesis of rational expectations — the notion that individuals form predictions using all available information, including the effects of policy itself. That work transformed how the field approached economic policy and earned him the Nobel Memorial Prize in Economic Sciences in 1995. N. Gregory Mankiw later called him "the most influential macroeconomist of the last quarter of the 20th century." By 2020 he ranked as the 10th most cited economist in the world. He died May 15, 2023.
