We study economies with an essential role for liquid assets in transactions. The model can generate multiple stationary equilibria, across which asset prices, market participation, capitalization, output and welfare are positively related. It can also generate a variety of nonstationary...

Recent work has reduced the gap between search-based monetary theory and mainstream macroeconomics by incorporating into the search model some centralized markets as well as some decentralized markets where money is essential. This paper takes a further step towards this integration by...

This paper extends the literature on search-theoretic models of money in several ways. It provides results for general bargaining parameters, whereas previous papers consider only special cases. It also presents one version of the model in which agents holding money cannot produce and another in...

We study general equilibrium with nonconvexities. In these economies there exist sunspot equilibria without the usual assumptions needed in convex economies, and they have good welfare properties. Moreover, in these equilibria, agents act as if they have quasi-linear utility. Hence wealth...

We study models that combine search, monetary exchange, price posting by sellers, and buyers with preferences that differ across random meetings - say, because sellers in different meetings produce different varieties of the same good. We show how these features interact to influence the price...

This paper pursues a line of Cass and Shell, who advocate monetary models that are "genuinely dynamic and fundamentally disaggregative" and that incorporate "diversity among households and variety among commodities." Recent search-theoretic models fit this description. The authors show that,...

Many individuals simultaneously have significant credit card debt and money in the bank. The credit card debt puzzle is: given high interest rates on credit cards and low rates on bank accounts, why not pay down debt? While some economists go to elaborate lengths to explain this, we argue it is...

We compare three market structures for monetary economies: bargaining (search equilibrium); price taking (competitive equilibrium); and price posting (competitive search equilibrium). We also extend work on the microfoundations of money by allowing a general matching technology and entry. We...

Simple search models have equilibria where some agents accept money and others do not. We argue such equilibria should not be taken seriously - which is unfortunate if one wants a model with partial acceptability. We introduce heterogeneous agents and show partial acceptability arises naturally....

The paper documents how cyclical fluctuations in market work vary over the life cycle and then assesses the predictions of a life-cycle version of the growth model for those observations. The analysis yields a simple but striking finding. The main discrepancy between the model and that data lies...
