Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A sticky-price model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

Several recent studies imply that the response of national saving to fiscal policy is non-monotonic. In this paper, we use two data sets to search for the circumstances in which such non-monotonic responses arise: one refers to a sample of OECD countries, as in previous studies, and one to a...

New Keynesian models of the business cycle have become the new paradigm of monetary economics, often used for policy analysis. This paper shows that this class of models fail in one crucial respect: they imply a strong negative contemporaneous correlation between inflation and output....

The paper considers the problem of autonomous recessions in the Russian economy, which are explained as a drop of the output caused by endogenous shocks of the supply and/or demand. In order to determine possible factors of the autonomous recession we consider the stylized facts and other...

This 2003 Institute for Fiscal Studies Lecture addresses two sets of issues relevant to current and prospective future E(M)U members: the consequences of the Stability and Growth Pact for fiscal-financial sustainability and macroeconomic stability, and some risks associated with operational...

While most economists accept the desirability of expansion of deficits over the short term there are a number of theoretical arguments that lead to the conclusion that higher government debt ratios might depress growth or lead to national insolvency. These have been further ?strengthened?...

Using an optimisation-based model with endogenous labour supply and a proportional tax rate, we compare the stabilising properties of different fiscal policy rules. The economy is affected by shocks from both government spending and technology. The fiscal policy rule can be based on government...

This paper considers a time varying parameter extension of the Ruge-Murcia (2003, 2004) model to explore whether some of the variation in parameter estimates seen in the literature could arise from this source. A time varying value for the unemployment volatility parameter can be motivated...
