I am an applied economist interested in understanding the determination of aggregate labor market outcomes, and how labor markets generate different outcomes for individuals with different characteristics (e.g. race, skill, etc.).  

My research approach can be described by two main features. First, it is grounded on theories of the labor market that emphasize that employers and workers are heterogeneous and take time and resources to match with each other (the search and matching approach). Second, it employs different quantitative methods and sources of microdata to either establish new facts on the operation of labor markets, measure new data moments, or estimate parameters of theoretical models that can be used to develop, quantitatively assess, or calibrate aggregate models of the labor market. 

I have worked on the cyclical behavior of part-time employment. Using data from the United States and the United Kingdom, my co-author and I have shown that the share of workers on part-time employment increases systematically and substantially during economic downturns. Moreover, we showed that recessionary increases in part-time employment are largely involuntary from the workers’ point of view, and that they are overwhelmingly accounted for by a reduction in employees’ working hours at their current employer.  

In ongoing research, I develop a new method to measure worker mobility rates across employers for several European countries over a long period. I uncover large differences in employer-to-employer mobility across European countries and the United States, as well as large and systematic variation over the business cycle in most countries. These facts are important to assess cross-country differences in aggregate wage mobility, as well as the evolution of wage inflation.
