Liquidity, Default And Crashes: Endogenous Contracts In General Equilibrium, John Geanakoplos Aug 2001

Liquidity, Default And Crashes: Endogenous Contracts In General Equilibrium, John Geanakoplos

Cowles Foundation Discussion Papers

The possibility of default limits available liquidity. If the potential default draws nearer, a liquidity crisis may ensue, causing a crash in asset prices, even if the probability of default barely changes, and even if no defaults subsequently materialize. Introducing default and limited collateral into general equilibrium theory (GE) allows for a theory of endogenous contracts, including endogenous margin requirements on loans. This in turn allows GE to explain liquidity and liquidity crises in equilibrium. A formal definition of liquidity is presented. When new information raises the probability and shortens the horizon over which a fixed income asset may default, …

This in turn allows GE to explain liquidity and liquidity crises in equilibrium. A formal definition of liquidity is presented. When new information raises the probability a fixed income asset may default, its drop in price may be much greater than its objective drop in value because the drop in value reduces the relative wealth of its natural buyers, who disproportiantely own the asset through leveraged purchases. When the information also shortens the horizon over which the …

If You're So Smart, Why Aren't You Rich?Belief Selection In Complete And Incomplete Markets, Larry Blume, David Easley Aug 2001

If You're So Smart, Why Aren't You Rich?Belief Selection In Complete And Incomplete Markets, Larry Blume, David Easley

Cowles Foundation Discussion Papers

This paper provides an analysis of the asymptotic properties of consumption allocations in a stochastic general equilibrium model with heterogeneous consumers. In particular we investigate the market selection hypothesis, that markets favor traders with more accurate beliefs. We show that in any Pareto optimal allocation whether each consumer vanishes or survives is determined entirely by discount factors and beliefs. Since equilibrium allocations in economies with complete markets are Pareto optimal, our results characterize the limit behavior of these economies. We show that, all else equal, the market selects for consumers who use Bayesian learning with the truth in the support …
