We consider an economy in which firms need to invest in capital before they can advertise a job, while applicants may have to compete for jobs. Our aim is to investigate how this competition affects the investment decisions of firms. Our first result shows that the economy always generates the...

It is often argued that a mandatory minimum wage is binding only if the wage density displays a spike at it. In this paper we analyze a model with search frictions and heterogeneous production technologies, in which imposition of a minimum wage affects wages even though, after imposition, the...

A major criticism against staggered nominal contracts is that they give rise to the so called persistency puzzle - although they generate price inertia, they cannot account for the stylised fact of inflation persistence. It is thus commonly asserted that, in the context of the new Phillips curve...

This paper considers the problem of aggregation in the case of large linear dynamic panels, where each micro unit is potentially related to all other micro units, and where micro innovations are allowed to be cross sectionally dependent. Following Pesaran (2003), an optimal aggregate function is...

We analyse optimal discretionary games between a benevolent central bank and a myopic government in a New Keynesian model. First, when lump-sum taxes are available and public debt is absent, we show that a Nash game results in too much government spending and excessively high interest rates,...

Building upon a continuous-time model of search with Nash bargaining in a stationary environment, we analyze the effect of changes in minimum wages on labor market outcomes and welfare. While minimum wage increases invariably lead to employment losses in our model, they may be welfare-improving...

It is frequently argued that pure government-mandated severance transfers by the employer to the worker have neither employment nor welfare effect because they can be offset by private transfers from the worker to the employer. In this paper, using a dynamic search and matching model a la...

Is it desirable that central banks be more transparent in the communication of sensible information when agents have diverse private information? In practice, there exists some consensus about the benefits of acting in this way. However, other studies warn that increasing the precision of public...

This paper investigates theoretically and empirically the heterogeneous response of exporters to real exchange rate fluctuations due to product quality. Our model shows that the elasticity of demand perceived by exporters decreases with a real depreciation and with quality, leading to more...
