The apparent inconsistency between the Tobin Separation Theorem and the advice of popular investment advisors pointed out by Canner et al (1997) is shown to be explicable in terms of the hedging demands of optimising long-term investors in an environment in which the investment opportunity set...

This paper uses a noisy rational expectations model to derive predictions about the dynamic behaviour of the proportion of institutional money managers in a given country who are bullish about the equity market in different countries. The predictions are tested using monthly data for four...

The optimal portfolio strategy is developed for an investor who has detected an asset pricing anomaly but is not certain that the anomaly is genuine rather than merely apparent. He analysis takes account of the fact that the parameters of both the underlying asset pricing model and the anomalous...

This paper is concerned with the asset pricing implications of the substantial proportion of equity portfolios that are managed on an agency basis. Portfolio managers who act as agents are assumed to be concerned with the mean and variance of their return measured relative to a benchmark...

We analyze the risk characteristics and the valuation of assets in an economy in which the investment opportunity set is described by the real interest rate and the maximum Sharpe ratio. It is shown that, holding constant the beta of the underlying cash flow, the beta of a security is a function...

This paper presents an empirical test of the Brennan Kraus (1987) hypothesis of convertible bond financing, according to which firms signal their volatility by their choice of terms of the convertible issue. With additional assumptions about the nature of investors’ prior beliefs about...

We develop a simple framework for analyzing a finitehorizon investor’s asset allocation problem under inflation when only nominal assets are available. The investor’s optimal investment strategy and indirect utility are given in simple closed form. Hedge demands depend on the...

The relation between the volatilities of pricing kernels associated with di�erent currencies and the volatility of the exchange rate between the currencies is derived under the assumption of integrated capital markets, and the volatilities of the pricing kernels are related to the foreign...
