We present a model of aggregate fluctuations in which monopolistic firms face sunk costs to enter the production process and labor markets are characterized by search and matching frictions. Entrants post vacancies and are matched to idle workers. Our specification of sunk costs gives rise to a...

The purpose of this paper is to explore the microfoundations of the observed asymmetric movement in aggregate unemployment rates. Using U.S. data, we find that individual labor force participation responds asymmetrically to changes in local labor market conditions, consistent with the pattern of...

Higher oil-price shocks benefit unskilled workers relative to skilled workers: At the business-cycle frequency, energy prices and the skill premia display a strong, negative correlation. We assess the robustness of this negative correlation using several methods and data sources, including...

This paper is concerned with the business cycle dynamics in search-and-matching models of the labor market when agents are ex post heterogeneous. We focus on wealth heterogeneity that comes as a result of imperfect opportunities to insure against idiosyncratic risk. We show that this...

We explore the role of real wage dynamics in a New Keynesian business cycle model with search and matching frictions in the labor market. Both job creation and destruction are endogenous. We show that the model generates counterfactual inflation and labor market dynamics. In particular, it fails...

We develop a dynamic general equilibrium model where workers can engage in search while on the job. We show that on-the-job search is a key component in explaining labor market dynamics in models of equilibrium unemployment. The model predicts fluctuations of unemployment, vacancies, and labor...

While the volatility of job creations has been studied extensively, the survival chances of new jobs are less researched. The question when and how to expand a firm is of importance, both from the firm’s and from a macro perspective. Adjustment cost theories and arguments about option values...

We suggest a new method to analyze the success of firm creation by looking at the persistence of new jobs created in old and in new firms. Compared to survival rates of new versus old firms, this measure has the advantage that the sustainability of job creation in different circumstances is...

We incorporate remittances and microentrepreneurship (self-employment) into a small openeconomy business cycle model with capital and labor market frictions. Countercyclical remittances moderate the decline of households' consumption during recessions. These remittances also are used to finance...

This paper evaluates the ability of autoregressive models, professional forecasters, and models that incorporate unemployment flows to forecast the unemployment rate. We pay particular attention to flows-based approaches - the more reduced-form approach of Barnichon and Nekarda (2012) and the...
