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...

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. The authors develop a general equilibrium framework of a channel system and study the optimal policy. A...

Can there be too much trading in financial markets? To address this question, we construct a dynamic general equilibrium model, where agents face idiosyncratic preference and technology shocks. A financial market allows agents to adjust their portfolio of liquid and illiquid assets in response...

An increasing number of central banks implement monetary policy via a channel system or a floor system. We construct a general equilibrium model to study the properties of these systems. We find that a floor system is weakly optimal if and only if the target rate satisfies the Friedman rule....

While both public and private financial agencies supply asset markets with large quantities of information, they do not necessarily disclose all asset-related information to the general public. This observation leads us to ask what principles might govern the optimal disclosure policy for an...

The authors construct a dynamic stochastic general equilibrium model to study optimal monetary stabilization policy. Prices are fully flexible and money is essential for trade. The authors’ main result is that if the central bank pursues a price-level target, it can control inflation...
