In this paper, I compare a two-agent asset pricing model with the corresponding model with a continuum of agents. In a two-agent economy, interest rates respond to because each agent represents half of the population. These interest rate effects facilitate consumption smoothing. An agent in a...

This paper develops a theoretical framework for analyzing contracting imperfections in long-term employment relationships. We focus chiefly on limited enforceability and limited worker liquidity. Inefficient severance of employment relationships, payment of efficiency wages, the relative...

This paper develops a model with multiple steady states (low tax and low unemployment versus high tax and high unemployment) in which equilibrium selection is not conditioned on a sunspot variable. Instead, large temporary shocks initiate unavoidable transitions from one steady state to another....

This paper evaluates a class of endogenous job destruction models based on how well they explain the observed experiences of displaced workers. We show that pure reallocation models in which relationship-specific productivity drifts downward over time are difficult to reconcile with the evidence...

This paper analyzes the performance of heteroskedasticity-and-autocorrelation-consistent (HAC) covariance matrix estimators in which the residuals are prewhitened using a vector autoregressive (VAR) filter. We highlight the pitfalls of using an arbitrarily fixed lag order for the VAR filter, and...

In this paper, I present two different methods that can be used to obtain a concise set of descriptive results about the comovement of variables. The statistics are easy to interpret and capture important information about the dynamics in the system that would be lost if one focused only on the...

We develop and quantitatively implement a dynamic general equilibrium model with labor" market matching and endogenous job destruction. The model produces a close match with data on" job creation and destruction. Cyclical fluctuations in the job destruction rate serve to magnify the" effects of...

This paper explains the divergent behavior of European and US unemployment rates using a job market matching model of the labor market with an interaction between shocks and institutions. It shows that a reduction in TFP growth rates, an increase in real interest rates, and an increase in tax...

This paper considers the efficiency of financial intermediation and the propagation of business cycle shocks in a model of long-term relationships between entrepreneurs and lenders lenders may be constrained in their short-run access to liquidity. When liquidity is low, relationships are subject...

This paper develops asymptotic distribution theory for generalized method of moments (GMM) estimators and test statistics when some of the parameters are well identified, but others are poorly identified because of weak instruments. The asymptotic theory entails applying empirical process theory...
