This paper considers the pricing of corporate securities of a given firm, in particular equity, when investors do not have full information on the firm’s asset value. We show that under noisy asset information, the pricing of corporate securities leads to a nonlinear filtering problem. This problem is solved by a Markov chain approximation, leading to an efficient finite-dimensional approximati...

We study a simple model based upon the Lucas framework where heterogeneous agents behave rationally in a fully intertemporal setting but do not know other investors’ personal preferences, wealth or investment portfolios. As a consequence, agents initially do not know the equilibrium asset pricing function and must make guesses which they update via adaptive learning with constant gain. We demon...

Securitization with payments linked to explicit mortality events provides a new investment opportunity to investors and financial institutions. Moreover, mortalitylinked securities provide an alternative risk management tool for insurers. As a step toward understanding these securities, we develop an asset pricing model for mortality-based securities in an incomplete market framework with jump ...

Most asset returns are uncertain, not merely risky: investors do not know the probabilities of different future returns. A large body of evidence suggests that investors are averse to uncertainty, as well as to risk. This paper uses the model-based multiple-priors framework developed in Knox (2003) to analyze the dynamic portfolio and consumption choices of an uncertainty-averse (as well as ris...

Finance theory can be used to form informative prior beliefs in financial decision making. This paper approaches portfolio selection in a Bayesian framework that incorporates a prior degree of belief in an asset pricing model. Sample evidence on home bias and value and size effects is evaluated from an asset-allocation perspective. U.S. investors' belief in the domestic CAPM must be very strong...

We apply the Consumption-based Asset Pricing Model (CCAPM) of the finance literature to study the risk and return of household business assets in developing economies. Using monthly panel data from a household survey in rural Thailand, we find that higher exposure to aggregate, non-diversifiable risk, as measured by household beta or the co-movement of the return of the individual household ent...
