Emi Nakamura: Interview

Columbia University economist Emi Nakamura has spent much of her research career measuring price stickiness. She, along with frequent co-author and spouse Jón Steinsson, was one of the first researchers to analyze the micro data underlying the U.S. consumer price index (CPI), a dataset that provides the most broad-based measures of price rigidity for the U.S economy. They showed that previous measures from these data, which suggested a great deal of price flexibility, did not account for important nuances of retail prices, such as temporary sales.
