We study an infinite-horizon economy with two basic frictions that are typical in monetary models. First, agents’ trading paths cross at most once due to pairwise trade and other meeting obstacles. Second, actions must be compatible with individual incentives due to commitment and enforcement...

In monetary models in which agents are subject to trading shocks there is typically an ex-post inefficiency in that some agents are holding idle balances while others are cash constrained. This inefficiency creates a role for financial intermediaries, such as banks, who accept nominal deposits...

We study an economy in which exchange occurs pairwise, there is no commitment, and anonymous agents choose between random monetary trade or deterministic credit trade. To accomplish the latter, agents can exploit a costly technology that allows limited record-keeping and enforcement. An...

I highlight the importance of the distributional aspects of money's divisibility by comparing a search-theoretic model with random transfers of indivisible money balances, to one with deterministic transfers of partially divisible balances. Randomization allows price flexibility, as if money...
