We study the existence of equilibria with endogenously complete markets in a continuous-time, heterogenous agents economy driven by a multidimensional diffusion process. Our main results show that if prices are real analytic as functions of time and the state variables of the model then a suffi-...

Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in a continuous time model. Two ordinally equivalent versions are considered. The state price is not Markov in any of the versions,...

We derive the equilibrium interest rate and risk premiums using recursive utility for jump-diffusions. Compared to to the continuous version, including jumps allows for a separate risk aversion related to jump size risk in addition to risk aversion related to the continuous part. The jump part...

Motivated by the problems of the conventional model in rationalizing market data, we derive the equilibrium interest rate and risk premiums using recursive utility in continuous time. In a representative-agent framework our model allows for the separation of risk aversion from the time...

This paper provides an extended framework to study general equilibrium theory with commodity spaces possibly of infinite dimensions. Our approach overcomes some difficulties found in the literature since it allows the study of the equilibrium when consumption sets may have an empty interior. It...

This article shows that, as long as agents are required to maintain positive wealth, the presence of portfolio constraints may give rise to asset pricing bubbles in equilibrium even if there are unconstrained agents in the economy who can benefit from the induced arbitrage opportunity....

While most may believe that we have a good understanding of the linear sharing mechanism, we show that we may not. In a standard exchange economy with heterogeneous beliefs, we derive necessary and sufficient conditions for Pareto efficient linear sharing rules and present the unknown and...

In classical models of markets, the state of nature is revealed regardless of the actions agents take. If instead agents can uncover information they will determine which states can be distinguished and thus which goods are traded. Competitive equilibria can then be inefficient. One source of...
