Research agenda

I am an applied macroeconomist and, though I have worked on a wide range of topics, my research agenda has one overarching theme:

Bring more detailed data to bear to help us understand the patterns in the aggregate measures, like GDP per capita, inflation, and the unemployment rate, that are the focus of most macroeconomic models.

The rest of this page describes how most of my research applies this theme in the context of three broad topics. The final part describes some other projects that can not be categorized under these three headers.

Labor market frictions and unemployment dynamics

With respect to the labor market, I have focused on three types of data to better understand the dynamics of the U.S. labor market and those in other countries.


In a set of research papers with Michael Elsby and Ayșegül Șahin I have investigated the dynamics of the flows that drive the evolution of the stocks of unemployed, employed, and non-participants that are the most commonly analyzed labor market aggregates. We have looked at this in great detail for the United States, and have also done country comparisons. The main things I took away from this part of my research agenda are the following:

Job openings and the Beveridge curve

Wage dynamics

Economic growth and technology diffusion

Growth and technology adoption

Differences in per capita GDP levels across countries are extremely large and understanding the reasons for these big disparities in standards of living across the World is of first order importance for economists. There are many studies that analyze the cross-country differences in the levels and dynamics of per capita GDP.


Price setting and measurement of price indices and inflation

Price stickiness, price setting, and monetary policy

Measuring inflation in markets with product turnover
