This paper extends the recent recursive contract literature on optimal unemployment insurance and optimal welfare-to-work programs in order to study the constrained-efficient dynamic contract between government and unemployed worker when a costly "training technology" is available. We first...

In this paper, we study the impact on the aggregate economy of changes in individual risk and insurance. To this end, we use the analytical framework developed in Heathcote, Storesletten and Violante (2008). Our main finding is that insurable risk increases TFP by improving the allocation of...

in both a simple analytic model, where news shocks overcome the ``dynamic inconsistencies" documented in Estrella and Fuhrer (2002), and in a model that incorporates many of the real rigidities common to DSGE models. The paper calls for more thoughtful modeling of how information about...

Using a dynamic factor model, we uncover four main empirical regularities on international comovements in a long-run panel of real and nominal variables. First, the contribution of world comovements to domestic output growth has decreased over the post-WWII period. The contribution of regional...

of reputation building converges to a level strictly between 0 and 1. However, the two limiting cases differ in the number of third party signals invoked.

linear hidden action preferences exhibiting a preference for late resolution of uncertainty. The costly contemplation model (Ergin and Sarver (2008a)), as well as a generalization of the Kreps and Porteus (1978) model that allows for preference for flexibility in the sense of DLR (2001) are also...

and search for a difference in the pattern of environmental quality when technological progress is taken to be endogenous by extending Brock and Taylor (2003). Brock and Taylor define pollution production and abatement explicitly by considering pollution as an output of both production and...

Capacity addition and withdrawal decisions are among the most important strategic decisions made by firms in oligopolistic industries. In this paper, we develop and analyze a fully dynamic model of an oligopolistic industry with lumpy capacity and lumpy investment/disinvestment. We use our model...
