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 characterize equilibria with endogenous debt constraints for a general equilibrium economy with limited commitment in which the only consequence of default is losing the ability to borrow in future periods. First, we show that equilibrium debt limits must satisfy a simple condition that...

Market liquidity is typically characterized by a number of ad hoc metrics, such as depth (or market impact), volume, intermediation costs (such as breadth) etc. No general coherent denition seems to exist, and few attempts have been made to justify the existing metrics on welfare grounds. In...

Financial market liquidity has become increasingly fragmented across multiple trading platforms. We propose an intuitive welfare-based market quality metric that can properly aggregate local market conditions across both securities and trading venues. Our analysis rests on a general equilibrium...

We consider a model with real assets and restricted participation described by household specific price dependent short selling constraints. We show existence of equilibria for all elements in an explicitly characterized large subset of the set of economies.

The purpose of this paper is to present an application of a cach flow-based Contingent Claims Analysis (CCA) to equity valuation. The cach flow-based Contingent Claims Analysis is used to extend a traditional CCA toproblems with incomplete capital markets, overreacted markets of situations where...
