I am a macroeconomist interested in Market Power, Aggregate Productivity, and Public Finance. My work seeks to advance three research agendas:

• The first quantifies different sources of market power—monopoly and monopsony—and their impact on the macroeconomy.

• The second addresses the question, Why are some countries more productive than others?

• The third is concerned with policy and works toward detecting market failures in different aspects of economic life to propose optimal interventions.
