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 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...

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 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...

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...

Empirical studies have found that enhanced foreign competition can encourage or discourage innovation. To address this relationship, I examine a market structure in which a small number of large multi-product oligopolists compete with a large number of small single-product firms in the same...

During the last two decades, new research has greatly advanced our understanding of the structure of world trade. This article reviews the empirical literature that grew out of this effort, emphasizing the ways in which it relied on theoretical developments

Countries differ greatly in R&D spending, and these differences are particularly striking when comparing developed with developing countries. The paper examines the extent to which the benefits of R&D are concentrated in the investing countries. It is argued that significant benefits spill over...

First I describe a number of political economy approaches that have been developed to explain trade policies. All approaches are presented in a unified framework that helps to see the key differences among them. These comparisons revolve around tariff formulas that are predicted by political...
