This paper evaluates the importance of microeconomic irreversibilities for aggregate dynamics using a real-business-cycle (RBC) model characterized by investment irreversibilities at the establishment level. The main finding is that investment irreversibilities do not play a significant role in...

This paper studies a version of the neoclassical growth model where heterogeneous establishments are subject to partial irreversibilities in investment. Under such investment technology, the optimal decision rules of establishments are of the (S,s) variety. A novel contribution of the paper is...

This paper evaluates the short-run effects of introducing labor market flexibility to an economy characterized by large firing taxes. Different reforms are considered: 1) eliminating all firing taxes, 2) introducing flexible new contracts while retaining the firing taxes on workers employed...

In this paper I evaluate to what extent a real business cycle (RBC) model that incorporates search and leisure decisions can simultaneously account for the observed behavior of employment, unemployment and out-of-the-labor-force. This contrasts with the previous RBC literature, which analyzed...

This paper extends Hopenhayn and Rogerson's analysis of firing taxes by introducing a flexible form of capital and considering transitionary dynamics. The paper finds that capital is not important for understanding the long run and welfare effects of firing taxes. However, capital is crucial for...

This paper develops a Walrasian equilibrium theory of establishment level dynamics and matching frictions and uses it to evaluate the effects of congestion externalities in the matching process and determine the government interventions that are needed to implement a Pareto optimal allocation....

Fixed term employment contracts have been introduced in number of European countries as a way to provide flexibility to economies with high employment protection levels. We introduce these contracts into the equilibrium search model in Alvarez and Veracierto (1999), a version of the Lucas and...

Several countries are seriously considering the abandonment of their currency and its formal replacement with the U.S. dollar. Since 1991, Argentina has backed its currency with 100 percent reserves and successfully pegged it to the dollar. In doing so, it has already grappled with many issues...

This article analyzes the effects of advance notice requirements on aggregate output, wages, employment, and welfare levels. The author finds that, contrary to firing taxes, advance notice requirements do not lead to reduction in employment. However, they can reduce welfare levels considerably...
