The output gap is a key variable of business cycle analysis and policy. Obtaining reliable estimates for it, is very difficult, though. Most real-time estimates are frequently revised over time. The idea of this paper is to use various indicators, for example from business surveys, that (i) were...

This paper develops a sufficient-statistic formula for the unemployment gap-the difference between the actual unemployment rate and the efficient unemployment rate. While lowering unemployment puts more people into work, it forces firms to post more vacancies and to devote more resources to...

Based on a panel data model this paper investigates whether the effects of fiscal policy on national saving in Europe have changed after the Maastricht Treaty came into force. Recently Giavazzi, Jappelli and Pagano (2000) found evidence that national saving responds nonlinearly to fiscal policy...

The paper examines the sustainability of U.S. fiscal policy, finding substantial evidence in favor. I summarize the U.S. fiscal record from 1792-2003, critically review sustainability conditions and their testable implications, and apply them to U.S. data. I particularly emphasize the...

We investigate the empirical impact of violence as compared to other trade impediments on trade flows. Our analysis is based on a panel data set with annual observations on 177 countries from 1968 to 1999, which brings together information from the Rose [2004] dataset, the ITERATE dataset for...

In this paper we study the link between elections, fiscal policy and aggregate fluctuations. The set-up is a stylized dynamic stochastic general equilibrium model incorporating both technology and political re-election shocks. The later are incorporated via a two-party model with elections. The...
