We study optimal liquidity management, innovation, and production decisions for a continuum of firms facing financing frictions and the threat of creative destruction. We show that financing constraints lead firms to decrease production but may spur investment in innovation (R&D). We...

This paper presents an equilibrium model in a pure exchange economywhen investors have three possible sources of heterogeneity. Investorsmay differ in their beliefs, in their level of risk aversion andin their time preference rate. We study the impact of investors heterogeneityon equilibrium...

We provide a representation for the nonmyopic optimal portfolio of an agentconsuming only at the terminal horizon when the single state variable follows ageneral diusion process and the market consists of one risky asset and a risk-freeasset. The key term of our representation is a new object...

We calculate equilibria of dynamic double-auction markets in which agents aredistinguished by their preferences and information. Over time, agents are privatelyinformed by bids and offers. Investors are segmented into groups that differ withrespect to characteristics determining information...

We study the existence of dynamic equilibria with endogenously complete markets incontinuous-time, heterogenous agents economies driven by diusion processes. Ourmain results show that under appropriate conditions on the transition density ofthe state variables, market completeness can be deduced...
