The paper examines a game-theoretic model of a financial market in which asset prices are determined endogenously in terms of short-run equilibrium. Investors use general, adaptive strategies depending on the exogenous states of the world and the observed history of the game. The main goal is to...

We analyze complex bond portfolios within the framework of a dynamic general equilibrium asset-pricing model. Equilibrium bond portfolios are nonsensical and imply a trading volume that vastly exceeds observed trading volume on financial markets. Instead, portfolios that combine bond ladders...

Trading volume of infinitely lived securities, such as equity, is generically zero in Lucas asset pricing models with heterogeneous agents. More generally, the end-of-period portfolio of all securities is constant over time and states in the generic economy. General equilibrium restrictions rule...

The trading volume of long-lived securities with recursive payoffs, such as equity, is generically zero in infinite-horizon recursive pure exchange Lucas asset models with heterogeneous agents. In equilibrium, there is no portfolio rebalancing of such assets. More generally, the end-of-period...

The two-fund separation theorem from static porfolio analysis generalizes to dynamic Lucas-style asset model only when a consol is presemt. If all bonds have finite maturity and do not span the consol, then equilibrium will devitate, often significantly, from two-fund separation even with the...

Equilibrium allocations in models with incomplete markets are generally not Pareto-efficient, but some argue that the welfare losses from missing assets are small when time-horizons are long, agents are patient, and shocks are transitory. We show that even in the simplest infinite horizon model...

We consider a Lucas asset-pricing model with heterogeneous agents, exogenous labor income, and a finite number of exogenous shocks. Although agents are infinitely lived, endowments and dividends are time-invariant functions of the exogenous shock alone and are thus restricted to lie in a...

Many assets derive their value not only from future cash flows but also from their ability to serve as collateral. In this article, we investigate this collateral premium and its impact on asset returns in an infinite‐horizon general equilibrium model with heterogeneous agents. We document...

In this paper we examine the effect of collateral constraints and margin requirements on the prices of long-lived assets. We consider a Lucas-style infinite-horizon exchange economy with heterogenous agents and collateral constraints. In our calibrated economy collateral constraints lead to a...
