In this paper the authors study the inefficiencies of the monetary equilibrium and optimal monetary policies in a search economy. They show that the same frictions that give fiat money a positive value generate an inefficient quantity of goods in each trade and an inefficient number of trades...

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...

We revisit classic questions concerning the effects of money on investment in a new framework: a two-sector model where some trade occurs in centralized and some in decentralized markets, as in recent monetary theory, but extended to include capital. This allows us to incorporate novel elements...

A construction of a nonsymmetric, pure-strategy equilibrium payoff-equivalent to the symmetric, mixed-strategy equilibrium.

Search-theoretic models of monetary exchange are based on explicit descriptions of the frictions that make money essential. However, tractable versions usually have strong assumptions that make them ill suited for discussing some policy questions, especially those concerning changes in the money...

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 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...

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...
