Using a segmented market model that includes state-dependent asset market decisions along with access to credit, we analyze the impact that transactions credit has on interest rates and prices. We find that the availability of credit substantially changes the dynamics in the model, allowing...

In a simple search model of money, we study a special kind of memory which gives rise to an arrangement resembling a payment network. Specifically, we assume that agents can choose to have access to a central data base which keeps track of payments made and received. We show that multiple...

A segmented markets model is constructed in which transactions are conducted using credit and currency. Goods market segmentation plays an important role, in addition to the role played by conventional segmentation of asset markets. An important novelty of the paper is to show how the diffusion...

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...

This paper analyzes monetary exchange in a search model allowing for multilateral matches to be formed, according to a standard urn-ball process. We consider three physical environments: indivisible goods and money, divisible goods and indivisible money, and divisible goods and money. We compare...

Many individuals simultaneously have significant credit card debt and money in the bank. The so-called credit card debt puzzle is, given high interest rates on credit cards and low interest rates on bank accounts, why not pay down this debt? Economists have gone to some lengths to explain this....

A model is developed that employs recent developments in the literature on search models of money to capture the distributional effects of monetary policy in a tractable way. Deterministic and stochastic versions of the model are studied. Money is not neutral, and these non-neutralities persist,...

We use a modified version of the Lagos-Wright model to introduce an essential role for banks. Due to preference shocks, agents have excess demand for or supply of money balances. Banks arise to reallocate excess cash by taking deposits from sellers and making loans to buyers. We consider two...

In this preliminary version we consider different types of ex-ante heterogeneity (production cost, preferences, market access, etc.) in a Lagos-Wright (2003) framework. Such heterogeneity generates equilibrium inequality in nominal wealth, or money holdings. We have two basic objectives. First,...
