We study the interplay between competition and trust as efficiencyenhancing mechanims in the private provision of money. With commitment, trust is automatically achieved and competition ensures efficiency. Without commitment, competition plays no role. Trust does play a role but requires a bound on efficiency. Stationary inflation must be non-negative and, therefore, the Friedman rule cannot be...

I apply mechanism design to quantify the cost of in‡ation that can be attributed to monetary frictions alone. In an environment with pairwise meetings, the money demand that is consistent with an optimal, incentive feasible allocation takes the form of a continuous correspondence that can …t the data over the period 1900-2006. For such parameterizations, the cost of moderate in‡ation is zero. T...

Existence of a monetary steady state is established for a random matching model with divisible goods, indivisible money, an arbitrary bound on individual money holdings, and take-it-or-leave-it offers by consumers. The background environment is that in papers by Shi and by Trejos and Wright. The monetary steady state shown to exist has nice properties: the value function, defined on money holdi...

Sharp exchange rate depreciations in the East Asian crisis countries (Indonesia, Korea, and Thailand) raised doubts about the efficacy of increasing interest rates to defend the currency. Using a standard monetary model of exchange rate determination, this paper shows that tighter monetary policy was in fact associated with an appreciation of the exchange rate in these countries and during the ...

Channel systems for conducting monetary policy are becoming increasingly popular. Despite its popularity, the consequences of implementing policy with a channel system are not well understood. We develop a general equilibrium framework of a channel system and study the optimal policy. A novel aspect of the channel system is that a central bank can “tighten” or “loosen” its policy without changi...

I explore alternative central bank policies for liquidity provision in a model of payments. I use a mechanism design approach so that agents’ incentives to default are explicit and contingent on the credit policy designed. In the first policy, the central bank invests in costly enforcement and charges an interest rate to recover costs. I show that the second-best solution is not distortionary. ...

We study the trade of indivisible goods using credit, divisible money and divisible assets in a frictional market. We show how indivisibility matters for equilibria. Bargaining generates a price that is not linked to nominal interest rates, dividend value of the asset, or the number of active buyers. To reestablish this connection, we consider price posting with competitive search. We provide c...

Several non-cash record-keeping systems are formulated in a randommatching model. The crucial informational friction is that a seller’s endowment, which may be a random variable, and the transfer of goods to a buyer can only be observed by the traders in a pairwise meeting. With this friction monitoring of the payment is distinguished from monitoring of the complete transaction. For each implem...
