January 2016How Exporters Grow
with Doireann Fitzgerald, Stefanie Haller: w21935
We show that after firms enter new export markets, there are striking dynamics of quantities, but no dynamics of prices, controlling for both costs and selection. This points to an important role for demand in the growth of successful exporters, and to a nonprice mechanism through which quantity demanded grows. A model where firms engage in costly investment in customer base through marketing and advertising, and learn about their idiosyncratic demand, can qualitatively match these facts, along with a declining exit hazard. We structurally estimate the model and find that costs of adjusting customer base are key to explaining how exporters grow.
October 2014What Should I Be When I Grow Up? Occupations and Unemployment over the Life Cycle
with Martin Gervais, Nir Jaimovich, Henry E. Siu: w20628
Why is unemployment higher for younger individuals? We address this question in a frictional model of the labor market that features learning about occupational fit. In order to learn the occupation in which they are most productive, workers sample occupations over their careers. Because young workers are more likely to be in matches that represent a poor occupational fit, they spend more time in transition between occupations. Through this mechanism, our model can replicate the observed age differences in unemployment which, as in the data, are due to differences in job separation rates.
December 2013Technological Learning and Labor Market Dynamics
with Martin Gervais, Nir Jaimovich, Henry E. Siu: w19767
The search-and-matching model of the labor market fails to match two important business cycle facts: (i) a high volatility of unemployment relative to labor productivity, and (ii) a mild correlation between these two variables. We address these shortcomings by focusing on technological learning-by-doing: the notion that it takes workers time using a technology before reaching their full productive potential with it. We consider a novel source of business cycles, namely, fluctuations in the speed of technological learning and show that a search-and-matching model featuring such shocks can account for both facts. Moreover, our model provides a new interpretation of recently discussed "news shocks."
