Nakamura's research focuses on empirical issues in
macroeconomics, including
price stickiness, the impact of
fiscal shocks, and measurement errors in official statistics. Her citation for the John Bates Clark Medal from the American Economic Association states that Nakamura has "greatly increased our understanding of price-setting by firms and the effects of monetary and fiscal policies", and cited her "creativity in suggesting new sources of data to address long-standing questions". Nakamura is a prominent figure in the field of
new Keynesian economics, which incorporates microeconomic theories and ideas and places them into macroeconomic theories. Nakamura demonstrates this in her work, “Five facts about prices”, by including microdata from the Bureau of Labor Statistics to prove macroeconomic ideas. In another highly cited work, "Fiscal stimulus in a monetary union", she and Jón Steinsson use variation in United States government military spending across states to estimate the open-economy government spending multiplier, finding values substantially higher than one. This confirms the prediction of Keynesian macroeconomic models that fiscal stimulus can have substantial effects on output, particularly at the zero lower bound. This study continues to be referenced in policy discussions. ==Recognition==
