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...

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...

Economic models are meant to provide a framework to describe real-world economic activities. In principle, how well a model performs this task can be evaluated by how close the model’s simulated activities track the observed ones. A necessary .rst step in simulating a model is to choose values...

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...

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...

This paper contributes to the literature comparing the relative performance of financial intermediaries and markets by studying an environment in which a trade-off between risk sharing and growth arises endogenously. Financial intermediaries provide insurance to households against a liquidity...

We build a model in which financial intermediaries provide insurance to households against a liquidity shock. Households can also invest directly on a financial market if they pay a cost. In equilibrium, the ability of intermediaries to share risk is constrained by the market. This can be...

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...

In many models of financial intermediation, markets reduce welfare because they limit the amount of risk-sharing intermediaries can offer. In this paper we study a model in which markets also promote investment in a productive technology. A trade-off between risk sharing and growth arises...

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...
