We characterize the optimal sequential choice of monetary policy in economies with either nominal or indexed debt. In a model where nominal debt is the only source of time inconsistency, the Markov-perfect equilibrium policy implies the progressive depletion of the outstanding stock of debt,...

This paper examines the stochastic relationship between money and capital in an economy with spatially separated markets. The new ingredient of the model is that trades between markets may be desirable but are eliminated by market separation. When this cross-market friction is operative,...

We introduce household production and the production of houses (construction) into a monetary model. Theory predicts inflation, as a tax on market activity, encourages substitution into household production and hence investment in housing. In the model, the stock and appropriately-deflated price...

This paper studies the relationship between the availability of unsecured credit to households and unemployment. We extend the Mortensen-Pissarides model to include a goods market with search and financial frictions. Households, who have limited commitment, face endogenous borrowing constraints...

Freeman (1996a) is the first to formulate a model in which (i) debts are repaid with money and (ii) there can arise liquidity problems which give rise to a role for a central bank discount window. I ask whether this payment system is truly essential in his model. It is not because there is...

A random-matching model (of money) is formulated in which there is complete public knowledge of the trading histories of a subset of the population, called the banking sector, and no public knowledge of the trading histories of the complement of that subset, called the non bank sector. Each...

We consider a record keeping cost to distinguish checking deposits from currency in a model where means-of-payment decisions and liquidity of assets are modelled explicitly. An equilibrium exists where checks are used only in big transactions while cash is used in all transactions. Higher...

In contrast to previous literature, we show that it is possible to use interest rate rules in standard monetary models to implement equilibria that are globally unique. This is a contribution to a literature that either concentrates on conditions for local determinacy, or criticizes that...

This paper addresses the classic question: what are the welfare costs of inflation. We employ a model in which the ratios of currency to deposits and currency to reserves are endogenously determined. The model distinguishes quantitatively between three sources of welfare cost of inflation, and...

This paper identifies two channels through which the economy can generate endogenous inflation and output volatility, an empirical regularity, by introducing model uncertainty into a Lucas-type monetary model. The equilibrium path of inflation depends on agents' expectations and a vector of...
