This paper analyses the efficiency of the equilibrium allocation in a matching model with two types of workers and jobs. The basic assumption is that high-skill workers can perform both skilled and unskilled jobs, while low-skill workers can only perform unskilled jobs. Our first result shows...

Starting from the assumption that firms are more likely to adjust their prices when doing so is more valuable, this paper analyzes monetary policy shocks in a DSGE model with firm-level heterogeneity. The model is calibrated to retail price microdata, and inflation responses are decomposed into...

Recently, it has been claimed that full-information multiple equilibria in games with strategic complementarities are not robust, because generalizing to allow slightly heterogeneous information implies uniqueness. This paper argues that this "global games" uniqueness result is itself not...

This paper assesses the relative merits of panel time series models in forecasting sovereign default. It explores the contentious issue of whether controlling for time-series and country heterogeneity is important in forecasting emerging market default. For this purpose, it uses conventional...

This paper investigates the performance of efficient portfolios in a financial market with heterogeneous investors including rational traders, noise traders, and chartists. A generalization of the security market line result states that, regardless of the diversity of beliefs, the portfolios of...

We quantitatively assess the role of on-the-job search for labor market dynamics in a fully specified, real DSGE model with endogenous job creation and destruction. The model features heterogeneity of the productivity of firms, across which workers search, as well as heterogeneity of jobs within...

Recent developments in the aggregation of large cross section of linear time series processes provide a complete characterization of the link between the dynamic properties of the aggregate series and the shape and degree of heterogeneity of the coefficients of the micro time series (see Lippi...
