We study a dynamic stochastic general equilibrium model in which agents are concerned about model uncertainty regarding climate change. An externality from greenhouse gas emissions damages the economy's capital stock. We assume that the mapping from climate change to damages is subject to...

We apply a mechanism design approach to a trading post environment where the household type space (tastes over variety) is continuous and it is costly to set up shops that trade differentiated goods. In this framework, we address Hotelling's <cite>Hot</cite> venerable question about where shops will...

Payments are increasingly being made with payment cards rather than currency-this despite the fact that the operational cost of clearing a card payment usually exceeds the cost of transferring cash. In this paper, the authors examine this puzzle through the lens of monetary theory. They consider...

A controversial aspect of payment cards has been the “no-surcharge rule.” This rule, which is part of the contract between the card provider and a merchant, states that the merchant cannot charge a customer who pays by card more than a customer who pays by cash. In this paper we consider the...

We describe a dynamic model of financial intermediation in which fundamental characteristics of the economy imply a unique equilibrium path of bank and financial market lending. Yet we also show that economies whose fundamental characteristics have converged may continue to have very different...

We investigate the role of settlement in a dynamic model of a payment system where the ability of participants to perform certain welfare-improving transactions is subject to random and unobservable shocks. In the absence of settlement, the full information first-best allocation cannot be...

The role of money in society has been a controversial topic in economic theory over many years. Particular attention has been devoted to the analysis whether there should be competition in the supply of money, or whether this is best left to a governmental agency. This paper reviews the...

We study economies where improving the quality of institutions – modeled as improving contract enforcement – requires resources, but enables trade that raises output by reducing the dispersion of marginal products of capital. We find that in this type of environment it is optimal to combine...

The behavior of interest rates under the U.S. National Banking System is puzzling because of the apparent presence of persistent and large unexploited arbitrage opportunities for note issuing banks. Previous attempts to explain interest rate behavior have relied on the cost or the inelasticity...

This paper proposes a theory of when labor contract should be nominal or, instead, indexed. We find that, contracts should be indexed if prices are difficult to forecast and nominal otherwise. We use a principal-agent model developed by Jovanovic and Ueda (1997), with moral hazard,...
