中村惠美对实证宏观经济学的贡献——2019年度约翰·贝茨·克拉克奖得主学术贡献评介

2019’s Clark Medalist Emi Nakamura’s Contributions to Empirical Macroeconomics

中村惠美因其在实证宏观经济学领域的突出贡献而荣获2019年度美国经济学联合会颁发的约翰·贝茨·克拉克奖。她因创造性地使用新数据来研究微观价格调整的特征、货币政策的非中性程度、通货膨胀的福利成本、货币政策和财政政策的效果等宏观经济学中长期存在争议的重大理论问题而闻名。相对于实证宏观经济学中常用的季度加总时间序列数据,中村使用的数据集具有加总更少、频率更高、时间跨度更长等特点。而且,她提出了更加有效的识别方法,从而能够对上述问题进行更加深入的研究并得到更加可靠的结论。

Emi Nakamura won the 2019 John Bates Clark Medal for her outstanding contributions to empirical macroeconomics. Nakamura's distinctive approach is notable for its creativity in suggesting new sources of data to study many long-standing questions in macroeconomics, including price-setting, the non-neutrality of monetary policy, the welfare costs of inflation and the effects of monetary and fiscal policies. The datasets she uses are more disaggregated, or higher-frequency, or extending over a longer historical period, than the postwar, quarterly, aggregate time series that have been the basis for most prior work on these topics in empirical macroeconomics. She also provides more effective identification methods, which enables her to study those questions more deeply and reaches more reliable conclusions.
