This work studies asset pricing in which the model combines dynamic learning and heterogeneous habit formations with agents' heterogeneous beliefs and preferences in a continuous-time, general-equilibrium, and international endowment economy. The intertemporal and frictionless equilibrium model...

What return should you expect when you take on a given amount of risk? How should that return depend upon other people's behavior? What principles can you use to answer these questions? In this paper, we approach these topics by exploring the consequences of two simple hypotheses about risk.The...

This paper studies asset pricing wherein the model combines dynamic learning and habit formation with agents' heterogeneous beliefs and preferences in a dynamic, stochastic, general-equilibrium, pure-exchange, international Lucas orchard. The intertemporal equilibrium model considers two groups...

This paper studies the implications of absence of arbitrage in economies where: (i) trade takes place in transaction time, (ii) there is a single state variable whose transaction-time price path is binomial, (iii) there are riskfree bonds with calendar-time maturities, and (iv) the relation...

We study an equilibrium asset pricing model with several Lucas (1978) trees subject toevent risk, that is, the possibility that trees experience unexpected disasters. We exploit themarket clearing mechanism, in the presence of multiple positive net supply assets, to showthat the implications of...

We revisit a standard model of security prices as Ito processes, and provide some new economic insights about the role of arbitrage and credit limits within such a model. We show that the standard assumptions of a positive state prices and existence of an equivalent martingale measure exclude...

We show that an unbounded number of consumption dates is necessary to support an asset pricing bubble. We work in a continuous-time model where the number of trade dates is infinite but the number of consumption dates is flexible and can be chosen to be uniformly bounded, finite almost surely,...

I extend the classical general equilibrium treatment of uncertainty about exogenous states of nature to uncertainty about prices. Traders do not know the prices at which markets will clear but have expectations over possible prices. They trade price-contingent securities (derivatives) to insure...

We study an equilibrium asset pricing model with several Lucas (1978) trees subject to persistent distress events, where the agent has incomplete information about the state of an underlying common factor and learns from the events occurring to each tree. Contrary to similar asset pricing models...
