This paper develops an equilibrium factor pricing theory when investors have heterogeneous beliefs about asset payoffs generated by the Ross linear factor model. Investors receive private information about the unknown parameters of the payoff process. They use this private information and equilibrium prices to predict asset payoffs. The paper develops a closed form price function for a noisy rational expectations equilibrium and relates it to the general solution. Even though we allow for a large number of investors, diversity of beliefs and parameter uncertainty both persist in equilibrium. We show that investors' beliefs about expected payoffs are approximately linear in the asset's betas, thus establishing the APT. As investors prefer to hold high information assets in equilibrium, the relative weight of these assets in the APT pricing bound is higher. The reverse is true for low information assets.

The paper provides sufficient conditions under which a nonrandom economic variable specific to some asset (the dependent variable) can be represented as a linear combination of the betas of some random characteristics of the asset (the independent variables) with some economy-wide factors. This generalizes Ross' APT that proves the above in the case where the dependent variables are expected returns and the independent variables are returns. This generalization will provide a theoretical basis for many existing multibeta relationships beyond the setting of asset pricing models and, thus, motivate their wider use in empirical and theoretical research.

This paper corrects the bond option formula presented by R. Rabinovitch ((1989), Equation (10)). With just one state variable driving the economy, the formula should be the same as the ones presented by Jamshidian (1989) and Chaplin (1987).

We examine the price behavior of the firm's common stock associated with cancelled straight debt offerings. Excluding utilities, we find negative excess returns associated with offering and cancellation announcements. Further, the stronger withdrawal reactions we find, when the funds were to be used for capital expenditures, may signal a decline in profitable investment opportunities. These results are consistent with Miller and Rock's (1985) hypothesis.

This paper derives a new and intuitive estimation procedure for the term structure under potential tax arbitrage. No a priori assumptions regarding the equality of the prices and present values of bonds are made. The data are employed to determine whether this equality holds, and an appropriate estimator is thereby endogenously derived. The suggested estimator is based on the optimizing behavior of an investor in a market with frictions, and emerges directly from the solution of the dual of the no-arbitrage optimization problem. In addition, the proposed estimator benefits from being both theoretically sound and straightforward to apply.

This paper develops a valuation formula for multi-period stochastic cash flows consistent with rational risk-averse investor behavior and equilibrium in securities markets. It shows that the CAPM does not have to be sequentially applied in discounting of the cash flows of multi-period projects, and a single beta can be used to measure the riskiness of an uncertain income stream. Hence, a multi-period project is priced as if it offers a single payment. The formula uses a set of assumptions that is slightly more restrictive than the minimum set Constantinides (1980) uses to produce the multi-period version of the CAPM. This paper also demonstrates that, under certain assumptions, covariances of stochastic cash flows with changes in the term structure may be sufficient measures of the cash flows' riskiness.
