Abstract

In a dynamic model with credit under limited commitment money can be essential when limited memory weakens the effects of punishment for default. There exist equilibria where both money and credit are used as media of exchange, and default occurs. In this equilibria the Friedman rule is not optimal. Inflation acts to discourage default by raising the cost of holding money, which is primarily held by defaulters. This results in relaxing the limited commitment constraint and raising welfare for all agents, including defaulting ones. The equilibrium is unique if and only if monetary policy and agents' money holdings are chosen sequentially.
