When it is costly for agents to find a match, integrating small markets into a larger one increases the matching difficulty. We examine such dependence of the number of matches on the market size by explicitely modelling firms' attempt to attract workers by posting wages. It is shown that...

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,...

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...
