I use a new technique to derive a closed-form solution for the price of a European call option on an asset with stochastic volatility. The model allows arbitrary correlation between volatility and spot-asset returns. I introduce stochastic interest rates and show how to apply the model to bond options and foreign currency options. Simulations show that correlation between volatility and the spot asset's price is important for explaining return skewness and strike-price biases in the Black-Scholes (1973) model. The solution technique is based on characteristic functions and can be applied to other problems.

The author investigates, in a two-country general equilibrium model, whether a bias in consumption towards domestic goods will necessarily lead to a preference for domestic securities. We develop a model where investors are constrained to consume only from their domestic capital stock and where it is costly to transfer capital across countries. In this model, investors less risk averse than an investor with log utility bias their portfolios towards domestic assets. Investors more risk averse than log, however, prefer foreign assets. Thus, this model suggests that it is unlikely that the portfolios observed empirically can be explained by the high proportion of domestic goods in total consumption.

This experiment factorially combined the major independent variables from previous demand-game experiments (discount factors, outside options, termination probability, and first mover). Game-theoretic predictions were largely refuted by the data and outcomes were often inefficient. Players without an outside option demanded more than predicted and those with an option appeared to anticipate this behavior. Nonetheless, there was a positive relationship between differences in equilibrium predictions and differences in behavior. Bargainers appeared to focus on a minimally acceptable offer in making their demands and in considering the likelihood that the other party would accept their offer.

This paper uses a nonlinear arbitrage-pricing model, a conditional linear model, and an unconditional linear model to price international equities, bonds, and forward currency contracts. Unlike linear models, the nonlinear arbitrage-pricing model requires no restrictions on the payoff space, allowing it to price payoffs of options, forward contracts, and other derivative securities. Only the nonlinear arbitrage-pricing model does an adequate job of explaining the time-series behavior of a cross section of international returns.

An example of a continuous time economy is given whose general equilibrium term structure of interest rates obeys the Expectations Hypothesis for continuously compounded interest rates and returns, contradicting the 1981 claim by Cox, Ingersoll, and Ross that such an economy is mathematically impossible. This example does not generate exploitable arbitrage opportunities of the type Cox, Ingersoll, and Ross claim must arise. The 'Logarithmic Expectations Hypothesis,' as we call it, is therefore an acceptable benchmark from which to measure term premia in continuous time term structure modeling.

The essential function of money is its role as a medium of exchange. The authors formalize this idea using a search-theoretic equilibrium model of the exchange process that captures the "double coincidence of wants problem" with pure barter. One advantage of the framework described here is that it is very tractable. The authors also show that the model can be used to addre ss some substantive issues in monetary economics, including the potenti al welfare-enhancing role of money, the interaction between specializat ion and monetary exchange, and the possibility of equilibria with multip le fiat currencies.

This paper develops a semiautoregression approach to estimate factors of the arbitrage pricing theory that has the advantage of providing a simple asymptotic variance-covariance matrix for the factor estimates, which makes it easy to adjust for measurement errors. Using the extracted factors, the author confirms the finding that the arbitrage pricing theory describes asset returns slightly better than the capital asset pricing model, although there is still some mispricing in the arbitrage pricing theory model. The author finds that not only are the factors priced by the market, but the factor premiums move over time in relation to business cycle variables.
