Bank loans are more available and cheaper for new and small businesses in the U.S. in concentrated banking areas than in competitive banking areas. We explain this anomaly by analyzing banks' decisions to screen projects and their competition in loan provisions. It is shown that, by exacerbating...

The log-normal Garman and Kohlhagen (1983) currency option model usually creates pricing biases when matched with the market prices. The observed price bias pattern is generally consistent with the mixed jump-diffusion distribution for exchange rates. Various studies have provided evidence of...

This paper uses an extension of the equilibrium model of Lucas (1978) to study the valuation of options on the market portfolio with return predictability, endogenous stochastic volatility and interest rates. Equilibrium conditions imply that the mean-reverting of the rate of dividend growth...

This paper integrates labor market search into an intertemporal equilibrium model to analyze the dynamic macroeconomic effects of a tariff. The model captures the intuitive argument in the earlier literature that a permanent increase in the tariff improves the country's terms of trade, which...

This paper introduces search unemployment into an intertemporal maximization model with capital accumulation. It characterizes the decentralized search equilibrium, examines the dynamic effects of factor income taxation and calculates the welfare cost of the taxation. Four tax policies are...

This paper looks at the joint determination of international indebtedness and capital accumulation in a two-country model. National rates of time preference are endogenous, and adjust along an optimal path to come into equality with one another in the steady state. A country's level of...

In this paper we construct a two-country search monetary model to determine the nominal exchange rate between two fiat monies. Our model imposes natural restrictions on agents' opportunities for arbitrage. These restrictions bind when the gross growth rates of the two currency stocks exceed the...

This paper constructs a model to show that plants differing in size pay different wages to homogeneous workers. A large plant can use its large capacity to satisify buyers in the product market more readily and so can charge a higher price than a small plant can. As a result, a large plant has a...

This paper examines efficient and equilibrium allocations in an economy where agents with diverse characteristics are matched through a time-consuming process to produce output. This is cast in a labour market where workers of different skills match with machines of different qualities. The...
