Price-setting models with monopolistic competition and costs of changing prices exhibit coordination failure: in response to a monetary policy shock, individual agents lack incentives to change prices even when it would be Pareto-improving if all agents did so. The potential welfare gains are in...

To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data...

This paper presents and estimates a sticky-price model with heterogenous households and financial frictions. Financial frictions lead to imperfect risk-sharing among households with idiosyncratic labor incomes. I study implications of imperfect risk-sharing for optimal monetary policy by...

We implement a new approach for the identification of news shocks about future technology. In a VAR featuring a measure of aggregate technology and several forward-looking variables, we identify the news shock as the shock orthogonal to technology innovations that best explains future variation...

Abstract In this paper I develop a multi-sector model with price frictions, production networks, trend inflation and different types of shocks to study how these conditions affect the properties of inflation and their implications for monetary policy. Calibrating the model to the U.S. economy my...

The paper investigates asymmetry in the allocation of aggregate demand shocks between real output growth and price inflation over the business cycle in a sample of fifteen Caribbean countries. In most countries, the evidence indicates the existence of structural constraints, implying that...

This paper proposes a structural explanation for a news shock. My hypothesis is that a surprise, research and development sector-specific productivity shock may be identified and labeled as news by prominent empirical research in the literature. To examine this hypothesis, I construct a simple...

This article examines the optimality of the Freidman rule in an overlapping generations model with spatial separation, wherein asymmetric liquidity shocks are observed. Suboptimality of the Freidman rule is shown. Furthermore, when the number of locations is sufficiently large, there is no room...
