We show how to use a simple perturbation method to solve non-linear rational expectation models. Drawing from the applied mathematics literature we propose a method consisting of series expansions of the non-linear system around a known solution. The variables are represented in terms of their...

We characterize the Laffer curves for labor taxation and capital income taxation quantitatively for the US, the EU-14 and individual European countries by comparing the balanced growth paths of a neoclassical growth model featuring ”constant Frisch elasticity” (CFE) preferences. We derive...

We compute average mark-ups as a measure of market power throughout time and study their interaction with fiscal policy and macroeconomic variables in a VAR framework. From impulse-response functions the results, with annual data for a set of 14 OECD countries covering the period 1970-2007, show...

Phenomena such as the Great Moderation have increased the attention of macro-economists towards models where shock processes are not (log-)normal. This paper studies a class of discrete-time rational expectations models where the variance of exogenous innovations is subject to stochastic regime...

Inflation expectations constitute a subject of particular contemporary interest to central banks, especially those pursuing a monetary policy based on a strategy of direct inflation targeting. Macroeconomic theory indicates that the transmission of monetary policy impulses and their impact on...

This paper provides a simple weekly model of the regular supply of liquidity in the euro area, with a view to understanding the functioning of the euro area money market. The main result of the analysis is that liquidity has normally been provided by the ECB in a neutral and smooth manner, but...

This Country Focus discusses the relation between public investment and economic growth in Poland. Theoretical and empirical work has shown that improvements in the quantity and quality of public infrastructure have a positive impact on growth in the medium and, possibly, in the long run. The...

Following several years of low growth Germany is presently enjoying a relatively strong recovery. With unemployment falling at record speed and fiscal consolidation progressing, the upswing is set to continue in spite of uncertainties surrounding the VAT increase of January 2007. This Country...

The Czech financial sector has changed dramatically since transition. In fifteen years, it has developed from a state-owned mono-bank into a privatised bank-based financial system with developing capital and private equity markets. This country focus analyses the development of the financial...
