Discussion Paper
Plant level irreversible investment and equilibrium business cycles

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 the analysis of the general equilibrium dynamics arising from aggregate productivity shocks. This is a difficult task given the high dimensionality of the state vector, which includes the distribution of establishments across capital levels and idiosyncratic shocks. The paper overcomes this difficulty ...

Labor market policies in an equilibrium search model

We explore to what extent differences in employment and unemployment across economies can be generated by differences in labor market policies. We use a version of the Lucas-Prescott equilibrium search model with undirected search and endogenous labor-force participation. Minimum wages, degree of unionization, firing taxes, and unemployment benefits are introduced and their effects analyzed. When the model is calibrated to US observations it reproduces several of the elasticities of employment and unemployment with respect to changes in policies reported in the empirical literature. We find ...

Establishments dynamics and matching frictions in classical competitive equilibrium

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. The optimal policy, which involves a tax on the creation of help-wanted ads and an unemployment subsidy, is highly contractionary. However, it leads to large welfare gains. The policy also plays an important role in dampening the response of the economy to aggregate productivity shocks.

Establishments dynamics, vacancies and unemployment: a neoclassical synthesis

This paper develops a Walrasian equilibrium theory of establishment dynamics and matching frictions and uses it to analyze business cycle fluctuations. Two scenarios are considered: one in which the matching process is subject to congestion externalities and another in which it is not. The paper finds that the scenario with congestion externalities replicates U.S. business cycle dynamics much better than the scenario with efficient matching. Reallocation shocks improve the empirical behavior of the model in terms of microeconomic adjustments but have little consequences for aggregate dynamics.

Fixed term employment contracts in an equilibrium search model

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 Prescott island model, adapted to have undirected search and variable labor force participation. We model a contract of length J as a tax on separations of workers with tenure higher than J. We show a version of the welfare theorems, and characterize the efficient allocations. This requires solving a ...

Working Paper
Search, self-insurance and job-security provisions

We construct a general equilibrium model to evaluate the quantitative effects of severance payments in the presence of contracting and reallocational frictions. Key elements of the model are: 1) establishment level dynamics, 2) imperfect insurance markets, and 3) variable search decisions. Contrary to previous studies that analyzed severance payments in frictionless environments, we find that severance payments reduce unemployment, produce negative insurance effects and improve levels.

Working Paper
Plant level irreversible investment and equilibrium business cycles

This paper evaluates the importance of microeconomic irreversibilities for aggregate dynamics using a general equilibrium approach. To this end a real business cycle model of establishment level dynamics is formulated and analyzed. Investments decisions are subject to irreversibility constraints and consequently, are of the (S,s) variety. This complicates the analysis since the state of the economy is described by an endogenous distribution of agents. The paper develops a computational strategy that makes this class of (S,s) economies fully tractable. Contrary to what the previous literature ...

Employment flows, capital mobility, and policy analysis

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 determining the short run consequences of eliminating this type of policy.

Gross Migration, Housing and Urban Population Dynamics

Cities experience significant, near random walk productivity shocks, yet population is slow to adjust. In practise local population changes are dominated by variation in net migration, and we argue that understanding gross migration is essential to quantify how net migration may slow population adjustments. Housing is also a natural candidate for slowing population adjustments because it is difficult to move, costly to build quickly, and a large durable stock makes a city attractive to potential migrants. We quantify the influence of migration and housing on urban population dynamics using a ...

Working Paper
Adverse Selection, Risk Sharing and Business Cycles

I consider a real business cycle model in which agents have private information about an idiosyncratic shock to their value of leisure. I consider the mechanism design problem for this economy and describe a computational method to solve it. This is an important contribution of the paper since the method could be used to solve a wide class of models with heterogeneous agents and aggregate uncertainty. Calibrating the model to U.S. data I find a striking result: That the information frictions that plague the economy have no effects on business cycle fluctuations.
