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...

We explain why underpricing in IPOs can be large in magnitude and clustered, using a signalling model where firms have private information about their qualities (high or low). A novel feature is that a firm, if perceived by the market as high quality, benefits from the industry's publicity which...

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 contributes to the search theory of unemployment by endogenously deriving matching functions and surplus sharing rule for skilled and unskilled workers from a wage-posting game. In contrast to previous wage posting models, here both sides of the market are heterogeneous and the...

This paper extends the Kiyotaki-Wright search model of fiat money to allow for divisible money and goods. The extension allows me to examine the standard issues in monetary economics, such as the neutrality and super-neutrality of money, by severing the artificial link in the Kiyotaki-Wright...

This paper makes commodities divisible and incorporates bargaining into the search-theoretic model of money to determine the purchasing power of money (or price). It is shown that two monetary equilibria always coexist where flat money is universally accepted. The two equilibria differ in price,...

Dispersion of money balances among individuals is the basis for a range of policies but it has been abstracted from in monetary theory for tractability reasons. In this paper, we fill in this gap by constructing a tractable search model of money with a non-degenerate distribution of money...

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...
