The authors develop a variant of Townsend's turnpike model where the trading friction is related to a commitment problem rather than spatial separation alone. Specifically, expenditure on financial services is necessary to ensure commitment. When commitment is costless, the equilibrium...

We study how credit scoring impacts the ability of individuals to consumption smooth. Our environment has ex-ante heterogeneity of household types. Credit scoring is interpreted as an intermediary's posterior of a household's type conditional on its bankruptcy and borrowing decisions. The...

The authors study the monetary theory implications of fixed costs associated with trade in private assets. The authors show that with heterogeneous endowment profiles it is possible for an endogenous subset of agents to hold currency even when it is dominated in return by a competing asset. With...

We study, theoretically and quantitatively, the equilibrium of an unsecured consumer credit industry where credit-suppliers take deposits at a given interest rate and offer loans to households via a menu of credit levels and associated interest rates. The loan industry is competitive, with free...

We study, theoretically and quantitatively, the general equilibrium of an economy in which households smooth consumption by means of both a riskless asset and unsecured loans with the option to default. The default option resembles a bankruptcy filing under Chapter 7 of the U.S. Bankruptcy Code....

We present a theory of unsecured consumer debt that does not rely on utility costs of default or on enforcement mechanisms that arise in repeated-interaction settings. The theory is based on private information about a person's type and on a person's incentive to signal his type to entities...
