We analyze the dynamics of inflation in an economy characterized by a forward-looking, staggered, price and wage determination process, and by monetary accommodation. In our model, inflation reconciles the conflicting claims of workers and firms. The model is capable of generating a positive...

This paper presents a new set of empirical regularities on the link between interest rates, money supply announcements and monetary base announcements. Among the main findings reported are: (i) unexpected increases in the announced monetary base have a significantly positive effect on interest...

This paper characterizes empirically how government budget variables, such as spending, taxes, and deficits, affected private-sector consumption in the high-budget-deficit economy of Israel during the first half of the 1980s. The paper develops and estimates an intertemporal optimizing model of...

The purpose of this paper is to provide empirical answers to questions related to the propagation of shocks in a high-inflation economy. Do one-time inflationary shocks give rise to long-term persistence, or inertia? Do balance of payments' shocks trigger a process that, through indexation and...

The purpose of this paper is to develop and estimate a stochastic-intertemporal model of consumption behavior and to use it for testing a version of the Ricardian-equivalence proposition with time series data. Two channels that may give rise to deviations from this proposition are specified:...

This paper develops and estimates a dynamic optimizing model of the current account. The model focuses, on real factors that determine the evolution of saving and investment, and hence the external balance. Three types of shocks are at the center of the analysis: productivity shocks, shocks to...

We develop a neoclassical trade model with heterogeneous factors of production. We consider a world with two factors, labor and "managers", each with a distribution of ability levels. Production combines a manager of some type with a group of workers. The output of a unit depends on the types of...

This Economica Coase Lecture reviews research that has revolutionized the field of international trade and foreign direct investment. It explains the motivation behind the development of new analytical frameworks, the nature of these frameworks, and the empirical studies that sprouted from them.

We introduce firm and worker heterogeneity into a model of innovation-driven endogenous growth. Individuals who differ in ability sort into either a research sector or a manufacturing sector that produces differentiated goods. Each research project generates a new variety of the differentiated...

While neoclassical theory emphasizes the impact of trade on wage inequality between occupations and sectors, more recent theories of firm heterogeneity point to the impact of trade on wage dispersion within occupations and sectors. Using linked employer-employee data for Brazil, we show that...
