Reducing fixed cost duplication - a common justification for concentrated market structure - motivated the US government to relax the number of radio stations a firm could operate in any local market.  After deregulation the number of firms per market decreased.  The implied cost saving...

In this paper we use a dynamic structural life-cycle model to analyze the employment,fiscal and welfare effects induced by unemployment insurance. The model features a detailedspecification of the tax and transfer system, including unemployment insurance benefitswhich depend on an individual's...

We present a gravity model that accounts for multilateral resistance, firm heterogeneity and country-selectioninto trade, while accommodating asymmetries in trade flows. A new equation for the proportion of exporting…firms takes a gravity form: the extensive margin is also accected by...

Do better trade logistics reduce trade costs, raising a country´s exports? Yes, but the magnitude of the effectdepends on country size. Applying a new gravity model to a comprehensive logistics index, we …nd that anaverage-sized country would raise exports by about 46% after a one-standard...

In this paper we develop a dynamic structural life-cycle model of labor supplybehavior which fully accounts for the eects of income tax and transfers on la-bor supply incentives. Additionally, the model recognizes the demand side drivenrationing risk that might prevent individuals from realizing...

This paper considers the problem of determining the extent of any state dependen-cies in women's labor supply behavior. Employment outcomes are modeled using adynamic multinomial choice framework including persistent unobserved heterogeneitywith a relatively general distribution. In order to...
