We construct a dynamic stochastic general equilibrium model to study optimal monetary stabilization policy. Prices are fully ‡exible and money is essential for trade. Our main result is that if the central bank pursues a price-level target, it can control in‡ation expectations and improve welfare by stabilizing short-run shocks to the economy. The optimal policy involves smoothing nominal inter...

We consider a multiagent network model consisting of nodes and edges as cities and their links to neighbors, respectively. Each network node has an agent and priced goods and the agent can buy or sell goods in the neighborhood. Though every node may not have an equal price, we show the prices will reach an equilibrium by iterating buy and sell operations. First, we present a protocol model in w...

This article studies optimal monetary policy when decision-makers in firms choose how much attention they devote to aggregate conditions. When the amount of attention that decision-makers in firms devote to aggregate conditions is exogenous, complete price stabilization is optimal only in response to shocks that cause efficient fluctuations under perfect information. When decision-makers in fir...

Two separate bodies of literature on stabilization give radically different results, yet these contradictions do not appear to have attracted any attention until now. The first arises from the neoclassical theory of stabilization and predicts that beneficial stabilization will always attract positive supply response. The second arises from the work of Newbery and Stiglitz and predicts 'perverse...

This paper studies the role of stabilization policy in a model where …rm entry responds to shocks and uncertainty. We evaluate stabilization policy in the context of a simple analytically solvable sticky price model, where …rms have to prepay a …xed cost of entry. The presence of endogenous entry can alter the dynamic response to shocks, leading to greater persistence in the e¤ects of monetary ...
