The Arbitrage Pricing Theory is extended to a setting where investors possess information about future asset returns. A no-arbitrage pricing restriction is obtained with arbitrage conditioned on an investor's information. The pricing restriction contains unconditional factor loadings and either conditional or unconditional expected returns. Thus, tests of the theory can be based solely on time-series estimates of unconditional moments. Additional tests based on conditional expected returns are also appropriate. 相似文献

Little research has been done on the economics of oilseeds and oilseed products, in proportion to their dietary importance in the world. The author discusses the political and economic aspects of the world oilseed market, as well as the main technical characteristics of the product. He argues that soybean is the key to stability in oilseed markets, and discusses possible policy options in the light of projected increases in both production and processing of oilseeds by developing countries. 相似文献

Summary This paper propounds a determinate and operational framework for the analysis of the oligopolistic firm's and industry's price-output equilibrium. It emphasizes the implicit collusion and restrained rivalry in the realistic market structure revealed by empirical investigators, and thereby takes a different route from the traditional Cournot-Stackelberg and game-theoretic approaches. It incorporates the multiobjective nature of the firm's decisionmaking, and draws upon nonlinear programming and parametric programming theory to offer a flexible framework to accommodate a wide variety of behavior patterns in such industries. Several simple examples employing fictional data are used to illustrate the models. 相似文献

Resource Scarcity and Agency Theory Predictions Concerning the Continued Use of Franchising in Multi-outlet Networks 总被引:3,自引:0,他引:3
Gary J. Castrogiovanni James G. Combs Robert T. Justis 《Journal of Small Business Management》2006,44(1):27-44
A study of 439 franchisors was conducted to identify factors influencing changes in their propensity to franchise. Consistent with agency theory, franchisors with wide multinational scope were increasing their proportion of franchised outlets whereas franchisors with large outlets were emphasizing firm ownership. As predicted by resource scarcity theory, franchisors were decreasing their proportion franchised as they grew in size, although most of the decrease occurred while firms were relatively small. In contrast to resource scarcity theory, franchisors increased their proportion franchised over time. Key implications are that both agency and resource scarcity theories are needed to explain franchising, but perhaps future research should look beyond resource scarcities toward resource-based capabilities to better explain franchising decisions. 相似文献
