I consider a model of directed search in which strategic sellers advertise general trading mechanisms. A mechanism determines the number of buyers that will get served and the side payments as a function of ex post realized demand. After observing these advertisements buyers simultaneously visit...

We study asset pricing within a general equilibrium model where unsecured credit is ruled out, and a real asset helps agents carry out mutually beneficial transactions by serving as collateral. A unique feature of our model is that the agent who provides the loan might have a low valu- ation for...

The FOREX market is an over-the-counter market (in fact, the largest in the world) characterized by bilateral trade, intermediation, and significant bid-ask spreads. The existing international macroeconomics literature has failed to account for these stylized facts largely due to the fact that...

I study a directed search model of oligopolistic competition, extended to incorporate general capacity constraints, congestion effects, and pricing based on ex-post realized demand. I show that as long as any one of these ingredients is present, the Bertrand paradox will fail to hold. Hence, I...

In many search models of the labor market, unemployment insurance (UI) is conveniently interpreted as the value of leisure or home production and is, therefore, treated as a parameter. However, in reality, UI has to be funded through taxation that might be distortionary. In this paper, I analyze...

We revisit a traditional topic in monetary economics: the relationship between asset prices and monetary policy. We study a model in which money helps facilitate trade in decentralized markets, as in Lagos andWright (2005), and real assets are traded in an over-the-counter (OTC) market, as in...

A consistent empirical feature of bond yields is that term premia are, on average, positive. That is, investors in long term bonds receive higher returns than investors in similar (i.e.\ same default risk) shorter maturity bonds over the same holding period. The majority of theoretical...
