Market innovations following the financial reforms of the early 1980s relaxed collateral constraints on household borrowing. The present paper examines the contribution of this development to the macroeconomic stabilization that occurred shortly thereafter. The model combines collateral...

This paper examines the effects of expected inflation on the responsiveness of output to nominal disturbances in the framework of a localized markets model. The mechanism described in the theoretical part of the paper is that expected inflation has a positive effect on the transaction frequency,...

An important "empirical regularity" is the strong positive effect of money shocks on output and employment. One strand of business cycle theory relates this finding to temporary confusions between absolute and relative price changes. These models predict positive output effects of unperceived...

This paper characterizes the labor supply and borrowing of a household facing collateral requirements that limit its debt and compel it to accumulate equity in its durable goods stock. The household's discount rate exceeds the market rate of interest, so it would otherwise finance increased...

This paper reports an empirical test of a price dispersion equation, using data on the U.S. after World War II. The equation, derived elsewhere from aversion of the partial information-localized market models, relates price dispersion to the magnitude of changes in the aggregate disturbances. In...

A price dispersion equation is tested with data from the German hyper-inflation. The equation is derived from a version of Lucas' (1973) and Barro's (1976) partial information-localized market models. In this extension, different excess demand elasticities across commodities imply a testable...

This paper employs the benchmark heterogeneous-agent model used in macroeconomics to examine drivers of the rise in wealth inequality in the U.S. over the last thirty years. Several plausible candidates are formulated, calibrated to data, and examined through the lens of the model. There is one...

We use a new micro data set that covers all oil fields in the world to estimate a stochastic industry-equilibrium model of the oil industry with two alternative market structures. In the first, all firms are competitive. In the second, OPEC firms act as a cartel. This effort is a first step...

This paper builds a theory of the distribution of TFP across countries. The theory is based on the hypothesis that TFP improvements in a given country follow a Nelson-Phelps specification: they derive from past investments in the country itself and, through a spillover term, from past...

We analyze a dynamic stochastic general-equilibrium (DSGE) model with an externality through climate change from using fossil energy. A central result of our paper is an analytical derivation of a simple formula for the marginal externality damage of emissions. This formula, which holds under...
