[1] Originally specializing in mathematical economics and general equilibrium theory, since the late 1990s Bewley has gained renown for his work on sticky wages.
[2] In Bewley's 1999 book Why Wages Don't Fall During a Recession,[3] hundreds of interviews with executives, labor leaders, and other professionals establish morale as an important factor in why businesses are reluctant to decrease employee compensation at times of low demand.
In general equilibrium theory, Bewley (1972) established key existence results for models with infinitely many goods.
[6][7] Aiyagari (1994),[8] Huggett (1993),[9] and Krusell and Smith (1998)[10] are examples of Bewley models, each with many hundreds of citations according to Google Scholar.
Bewley was elected a fellow of the American Academy of Arts and Sciences in 2005.
