The Consumption - Based Capital Asset Pricing Model
Arrow-Debreu Existence Result Let K be a normed vector lattice with positive cone K+ (see Schaefer (1974)). We consider an Arrow-Debreu (pure exchange) economy 9'= (?, e') in K, with m agents described by preference relations > i on K+ and initial endowments e' E K+. Throughout, we make the usual assumptions on preferences: each >i is reflexive, transitive, complete, convex, continuous, and str...
متن کاملThe game-theoretic capital asset pricing model
Using Shafer and Vovk’s game-theoretic framework for probability, we derive a capital asset pricing model from an efficient market hypothesis, with no assumptions about the beliefs or preferences of investors. Our efficient market hypothesis says that a speculator with limited means cannot beat a particular index by a substantial factor. The model we derive says that the difference between the ...

متن کاملA Two State Capital Asset Pricing Model
A famous model in nancial theory is the Capital Asset Pricing Model (CAPM). In this paper we propose a two state CAPM in which we assume that excess returns for the market and for a particular security are bivariate normally distributed. The parameters of the distribution are determined by the state of an unobserved stationary Markov chain. Two states represent two business regimes that are cha...
