Remarks at the Quarterly Regional Economic Press Briefing, New York City.

We show that the inability of a standardly-calibrated stochastic labor search-and-matching model to account for the observed volatility of unemployment and vacancies extends beyond U.S. data to a set of OECD countries. We also argue that using cross-country data is helpful in evaluating the...

Remarks at the Quarterly Regional Economic Press Briefing, New York City.

U.S. CPS gross flows data indicate that in recessions firms actually increase their hiring rates from the pools of the unemployed and out of the labor force. Why so? The paper provides an explanation by studying the optimal recruiting behavior of the representative firm. This behavior is a...

I explore the implications of the lumpy labor adjustment as a propagation mechanism for aggregate dynamics. The model I use nests the basic RBC model with a staggered-job-turnover in the spirit of Taylor (1980) and Calvo (1983). It extends this approach by introducing a Weibull-distributed labor...

I explore the aggregate effects of micro lumpy labor adjustment in a prototypical RBC model, which embeds a stochastic labor duration mechanism in the spirit of Calvo(1983), and it extends this approach by introducing a Weibull-distributed labor adjustment process to capture the increasing...

In this article, I evaluate the hypothesis that firms respond to negative demand shocks by assigning workers to tasks that require less skill than the tasks they normally carry out. Using changes in employment in state-industry cells as a measure of demand conditions facing individual firms, I...

This thesis presents an examination of the importance of Small and MediumEnterprises (SMEs) for economic growth and examines how sensitive employment inSMEs is to business cycle fluctuations in Brazil.The thesis uses different empirical techniques to investigate the role of SMEsin the Brazilian...
