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...

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...
