This paper examines the conditions required to guarantee positive prices in the CAPM. Positive prices imply an upper bound on the equity premium. This upper bound depends on the degree of diversity of firms’ fundamentals, and it is independent of investors’ preferences. In economies with realistically diverse assets the only positive-price CAPM equilibrium theoretically possible is a degenerate...

The intertemporal CAPM predicts that an asset's price is equal to the expectation of the product of the asset's payoff and a representative consumer's intertemporal marginal rate of substitution. This paper develops an alternative approach to asset pricing based on industrial and financial corporations' desire to hoard liquidity to fulfill future cash needs. Our corporate finance approach to ma...

The non-tradability of human capital is often cited for the failure of traditional asset pricing theory to explain agents’ portfolio holdings. In this paper we argue that the opposite might be true — traditional models might not be able to explain agent portfolio holdings because they do not explicitly account for the fact that human capital does trade (in the form of labor contracts). We deriv...

This paper introduces a new methodology to estimate time-varying alphas and betas in conditional factor models, which allows substantial flexibility framework. To circumvent problems associated with the previous approaches, we introduce Bayesian parameter model where innovations of state equation have spike-and-slab mixture distribution. The distribution specifies two states specific probabilit...

Several real problems in telecommunication, transportation, and distribution industries can be well analyzed by network flow models. In revenue management, pricing plays a primary role which increases the profit generated from a limited supply of assets. Pricing decision directly affects the amount of service or product demand. Hence, in traditional maximum flow problem, we assume that the dema...

Valuing natural capital is fundamental to measuring sustainability. The United Nations Environment Programme, World Bank, and other agencies have called for inclusion of the value of natural capital in sustainability metrics, such as inclusive wealth. Much has been written about the importance of natural capital, but consistent, rigorous valuation approaches compatible with the pricing of tradi...

This paper offers an alternative method for estimating expected returns. The proposed reward beta approach performs well empirically and is based on asset pricing theory. The empirical section compares this approach with the CAPM and the Fama-French three-factor model. In out-of-sample testing, both the CAPM and the three-factor model are rejected. In contrast, the reward beta approach easily p...
