In many situations, some people hold large money balances but have no particular urgency to spend them while others are liquidity constrained. This problem creates a role for financial intermediaries who accept nominal deposits and make nominal loans. We show that financial intermediation...

The impact of fully anticipated inflation is systematically studied in heterogeneous agent economies with an endogenous labor supply and portfolio choices. In stationary equilibrium, inflation nonlinearly alters the endogenous distributions of income, wealth, and consumption. Small departures...

The directed search model (Peters, 1984) is static; its dynamic extensions typically restrict strategies, often assuming price or match commitments. We lift such restrictions to study equilibrium when search can be directed over time, without constraints and at no cost. In equilibrium trade...

We present a model that generates empirically plausible price distributions in directed search equilibrium. There are many identical buyers and many identical capacity-constrained sellers who post prices. These prices can be renegotiated to some degree and the outcome depends on the number of...

We study equilibrium prices and trade volume with n identical buyers and a seller who initially commits to some capacity. Sales are sequential and each price is determined by strategic bargaining. A unique sub-game perfect equilibrium exists. It is characterized by absence of costly bargaining...

The authors study how two fiat monies, one safe and one risky, compete in a decentralized trading environment. The equilibrium value of the two currencies, their transaction velocities and agents' spending patterns are endogenously determined. The authors derive conditions under which agents...

The illicit nonmedical use of prescription drugs is studied in a model where individuals with imperfectly observable health conditions seek prescription drugs for either medical or nonmedical reasons. The equilibrium number of medical and nonmedical users is endogenous and depends on economic...
