About Me

I am an associate professor of economics at Washington University in St. Louis. I teach macroeconomics, finance, and econometrics to undergraduate and graduate students. My research involves using statistical analysis to gain insights into a number of empirical issues in economics, including the following:

1. •   Are business cycle fluctuations symmetric? What are their sources and economic implications?
   

2. •   What is the nature of structural change in macroeconomic relationships? Is it gradual or abrupt?
   

3. •   Why has aggregate production become less volatile in recent years?
   

4. •   Why are aggregate household expenditures much less volatile than overall aggregate production?
   

5. •   What are the sources of persistent changes in the unemployment rate?
   

6. •   How does stock market volatility affect expected returns in the stock market?
   

7. •   Why are deviations from “the law of one price” so volatile and persistent across countries?
