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...

In designing a production model for firms that generate multiple outputs, we take as a starting point that such multi-output production refers to economies of scope, which in turn originate from joint input use and input externalities. We provide a nonparametric characterization of cost...

We extend the Svensson (1997a) inflation forecast targeting framework with a convex Phillips curve. We derive an asymmetric target rule, that implies a higher level of nominal interest rates than the Svensson (1997a) forward looking version of the reaction function popularised by Taylor (1993)....

We assess the procyclical effects of bank capital regulation in a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period. Banks anticipate that shocks to their earnings as well as the cyclical position of the economy can impair their...

Newly established firms often try to secure their market position by building up a base of loyal customers. While recessions may not destroy technological leadership, they may be harmful for such firm-customer relationships. Without such customer bases, these firms find themselves more...

This paper analyzes the controversy between Keynes and Tinbergen on econometric testing of business cycle theories. In his writings, Keynes repeatedly emphasizes a logical objection to Tinbergen s work. It is clarified what exactly this logical objection is, and why it matters for a statistical...
