Data on U.S. mergers and aquisitions from 1987 to 2006 indicate that firms with high market-to-book values (i.e., Tobin's Q) tend to merge with firms that have lower Q's, but that target Q's are on average higher than those of firms not involved in mergers at all. We capture this fact with a...

We show that Arrow-Debreu equilibria with countably additive prices in infinite-time economy under uncertainty can be implemented by trading infinitely-lived securities in complete sequential markets under two different portfolio feasibility constraints: wealth constraint, and essentially...

Staggered price and staggered wage contracts are commonly viewed as similar mechanisms in generating persistent real effects of monetary shocks. In this paper, we distinguish the two mechanisms in a dynamic stochastic general equilibrium framework. We show that, although the dynamic price...

We develop a theory of valuation of payoff streams in infinite-horizon sequential markets and discuss implications of this theory for equilibrium under various portfolio constraints. We study the nature of asset price bubbles in light of this theory. We show that there cannot be equilibrium...

We prove there exists and analyze a strategy that minimizes the cost of hedging a liability stream in infinite-horizon incomplete security markets with a type of constraints that feasible portfolio strategies form a convex cone. We provide a theorem that extends Stiemke Lemma to over cone...

A central challenge to monetary business cycle theory is to find a solution to the problem of persistence in the real effect of monetary shocks. Previous research has identified separately specific factors and intermediate inputs as two promising mechanisms for generating the persistence in a...

This paper analyzes a two-country general equilibrium model with multiple stages of production and sticky prices. Working through the cross-country input-output relations and endogenous price stickiness, the model generates the observed patterns in international aggregate comovements following...

Recent empirical studies reveal that monetary shocks cause persistent fluctuations in inflation and aggregate output. In the literature, few mechanisms have been identified to generate such persistence. In this paper, we propose a new mechanism that does so. Our model features an input-output...
