Dynamics of labor demand : evidence from plant-level observations and aggregate implications
This paper studies the dynamics of labor demand at the micro and aggregate level. The correlation of hours and employment growth is negative at the plant level and positive in aggregate time series. Further, hours and employment growth are about equally volatile at the plant level while hours growth is much less volatile than employment growth in the aggregate data. Given these differences, we specify and estimate the parameters of a plant-level dynamic optimization problem using simulated method of moments to match plant-level observations. Our findings indicate that non-convex adjustment ...

Designing stabilization policy in a monetary union
The European Monetary Union (EMU) has become a reality, but economists nonetheless continue to debate the desirability and the optimal design of a monetary union. Since a union's essential element is delegation of monetary power to a single centralized entity, one of the key issues in this debate is whether a monetary union will limit the effectiveness of stabilization policy. If so, it will not necessarily be welfare-improving. Having studied a two-country world economy and considered various designs of monetary union, the authors argue that the success of monetary union depends on 1) the ...

Hours and employment implications of search frictions: matching aggregate and establishment-level observations
This paper studies worker and job flows at the establishment and aggregate levels. The paper is built around a set of facts concerning the variability of unemployment and vacancies in the aggregate, the distribution of net employment growth and the comovement of hours and employment growth at the establishment level. A search model with frictions in hiring and firing is used as a framework to understand these observations. Notable features of this search model include non-convex costs of posting vacancies, establishment level profitability shocks and a contracting framework that determines ...

The cost of labor adjustment : inferences from the gap
We study labor adjustment costs. We specify a dynamic optimization problem at the plant-level, allowing for both convex and non-convex adjustment costs. We estimate the parameters of the adjustment process using an indirect inference procedure in which simulated moments are matched with data moments. For this study we use estimates of reduced form adjustment functions obtained by the "gap methodology" reported in Caballero and Engel (1993). Contrary to evidence at the micro level in support of non-convex adjustment costs, our preliminary findings indicate that piecewise quadratic adjustment ...

The economics of labor adjustment : mind the gap
We study the inferences about labor adjustment costs obtained by the "gap methodology" of Caballero and Engel [1993] and Caballero, Engel and Haltiwanger [1997]. In that approach, the policy function of a manufacturing plant is assumed to depend on the gap between a target and the current level of employment. Using time series observations, these studies reject the quadratic cost of adjustment model and find that aggregate employment dynamics depend on the cross sectional distribution of employment gaps. We argue that these conclusions may not be justified. Instead these findings may ...

Insulation impossible: fiscal spillovers in a monetary union
This paper studies the effects of monetary policy rules in a monetary union. The focus of the analysis is on the interaction between the fiscal policy of member countries (regions) and the central monetary authority. When capital markets are integrated, the fiscal policy of one country will influence equilibrium wages and interest rates. Thus there are fiscal spillovers within a federation. The magnitude and direction of these spillovers, in particular the presence of a crowding out effect, can be influenced by the choice of monetary policy rules. We find that there does not exist a monetary ...

Declining Responsiveness at the Establishment Level: Sources and Productivity Implications
This paper studies competing sources of declining dynamism. Evidence shows that an important component of this decline is accounted for by the reduction in the response of employment to shocks in US establishments. Using a plant-level dynamic optimization problem as a framework for analysis, four potential reasons for this decline are studied: (i) a change in exogenous processes for profits, (ii) an increase in impatience, (iii) increased market power, and (iv) increasing adjustment costs. We identify and quantity the contribution of each of these factors building on a simulated method of ...
