This paper tests the zero-beta CAPM with Australian equity returns, using the multivariate approach developed by Gibbons (1982). For the period 1958 to 1987, based on its asymptotic distribution, the likelihood ratio test (LRT) statistic indicates a strong rejection of the model when an equally weighted market index is used. However, small sample adjustments to the test suggested by Jobson and Korkie (1982) and by Shanken (1985) place the validity of this conclusion in some doubt. When a value weighted market index is used for the period 1974 to 1987, the tests reveal at least moderate support for the zero-beta CAPM. 相似文献

Several textbooks, journal articles, and advertising practitioners indicate that the advertising for many products should be directed toward the heavy users of the product category. Other works suggest that advertising should be directed at current users of a brand to retain them or to users of competitive brands in an effort to attract them. The purpose of this article is to compare these directions for how advertising should be placed with data showing how advertising is being placed. The comparison is made using supermarket scanner panel data and household advertising exposure data. Examples are also provided to indicate the extent to which advertising could be targeted to heavy users of the product category and users of a brand, given the actual viewing and consumption patterns. Several implications for the placement of advertising are discussed. 相似文献

We test whether default risk is related to equity returns using the Fama and MacBeth [Fama, E.F., MacBeth, J., 1973. Risk, return, and equilibrium: empirical tests. Journal of Political Economy 81, 607–636.] regression framework. The proxy we use for default risk is the default probability obtained from option-based models. Our findings show that default probability is negatively related to returns. While we find that size and book-to-market are related to default risk, the ability of these variables to explain cross-sectional variation in returns is not because they are proxying default risk. Further, our evidence suggests that the negative relationship between default probability and returns is not due to a leverage, volatility or momentum effect. 相似文献

Measuring Investment Distortions when Risk-Averse Managers Decide Whether to Undertake Risky Projects 总被引:2,自引:0,他引:2
We create a dynamic model in which a self-interested, risk-averse manager makes corporate investment decisions at a levered firm with characteristics typical of public US firms. We examine the magnitude of distortions in those decisions when a new project changes firm risk and find expected changes in the values of future tax shields and bankruptcy costs to be important factors. We evaluate the extent to which these distortions vary with firm leverage, debt duration, project size, managerial risk aversion, managerial non-firm wealth, and the structure of management compensation packages 相似文献

It is shown how, even when the market is incomplete, certain contingent claims are attainable: that is, they can be represented as stochastic integrals with respect to the process which describes the evolution of the asset prices. 相似文献
