In this paper we study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. We show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades (or search...

This paper studies the role of money in environments where in each meeting there is a double coincidence of real wants. Traders who meet at random finance their purchases through current production, the sale of divisible money or both. It is shown that in the absence of valued money if traders...

This paper studies the validity of the Friedman rule in a search model with divisible money and divisible goods where the terms of trades are determined endogenously. We show that ex post bargaining generates a holdup problem similar to the one emphasized in the labour-market literature. Buyers...

This paper investigates the role of fiat money in decentralized markets, where producers have private information about the quality of the goods they supply. Money is divisible, terms of trade are determined endogenously, and agents can finance their consumption with money or with real...

We use alternative assumptions about the divisibility of goods and money and the ability of agents to use lotteries on money to investigate to what extent the indivisibility of money is the cause for the typically inefficient production and consumption decisions in search-theoretic models of...

An increasing number of central banks implement monetary policy via two standing facilities: a lending facility and a deposit facility. In this paper we show that it is socially optimal to implement a non-zero interest rate spread. We prove this result in a dynamic general equilibrium model...

This paper studies the theoretical properties of a channel system of interestrate control in a dynamic general equilibrium model. Agents are subject to liquidity shocks which can be partially insured in a secured money market, or at a standing facility operated by the central bank. We show that...

We study the long-run relation between money, measured by inflation or interest rates, and unemployment. We first document in the data a positive relation between these variables at low frequencies. We then develop a framework where unemployment and money are both modeled using microfoundations...

When agents are liquidity constrained, two options exist — sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government bonds (outside bonds) and in the other they can borrow (issue inside bonds). All transactions are voluntary, implying no...

Many countries simultaneously suffer from high inflation, low growth and poorly developed financial sectors. In this paper, we integrate a microfounded model of money and finance into a model of endogenous growth to examine the effects of inflation on welfare, growth and the size of the...
