This paper integrates search-based models of marriage and money. We think about households as organizations, the way Coase thinks about firms, as alternatives to markets that become more attractive when transactions costs increase. In the model, individuals consume market- and home-produced...

Inflation and unemployment are central issues in macroeconomics. While much progress has been made on these issues by incorporating frictions using search theory, existing models analyze either unemployment or inflation. We develop a framework to analyze unemployment and inflation together. This...

We develop a model of commodity money and use it to analyze the following two questions motivated by issues in monetary history: What are the conditions under which Gresham's Law holds? And, what are the mechanics of a debasement (lowering the metallic content of coins)? The model contains light...

We study a market where innovators, who are good at coming up with ideas, can sell them to entrepreneurs, who might be better at implementing them. The market is decentralized, with random matching and bargaining. Ideas are characterized by five salient features: they are indivisible; partially...

Models of the exchange process based on search theory can be used to analyze the features of objects that make them more or less likely to emerge as ``money'' in equilibrium. These models illustrate the trade--off between endogenous acceptability (an equilibrium property) and intrinsic...

Multiperson households are less reliant on cash than single people because they are more likely than singles to rely on home-based production to meet their daily needs. This conclusion, supported by recent empirical research, suggests that fiscal and monetary policies that make market-based...

We study models of credit with limited commitment, which implies endogenous borrowing constraints. We show that there are multiple stationary equilibria, as well as nonstationary equilibria, including some that display deterministic cyclic and chaotic dynamics. There are also stochastic...
