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...

The new member states should not expect EU money to lead to miracles. The most important ingredients of catch-up growth are a stable macroeconomic framework; supply-side policies that help markets to adjust quickly; and a well-trained, flexible workforce. EU aid will only make a positive...

This study has evaluated the General and Sector Budget Support operations undertaken in Tanzania from 2005/06 to 2011/12. These operations amount to a resource transfer of almost US$5,000 million - an annual average disbursement of US$ 694 million, some $16 per annum per head of the Tanzanian...

The objective of this evaluation is to assess the extent to which budget support has contributed to achieving its expected results by helping the Government of Ghana (GoG) to strengthen the implementation of its national and sectoral strategies. The study covers all operations with disbursements...

This paper investigates a dynamic general equilibrium model with search. In particular, search externalities are reßected by an increasing returns to scale matching function, which may imply an indeterminate equilibrium. Hence, the model is capable to generate business ßuctuations, driven by...

For the new member states of the EU, the question of choosing the optimal macroeconomic policy mix is rather complicated as these countries are all in the dynamic movement towards joining the European Economic and Monetary Union (EMU). This implies a considerable change in macroeconomic policy...

Turkey is at a crossroads. After hitting the most severe crisis of its recent history in 2000-2001, the economy bounced back and is now among the fastest growing economies in the OECD. A new institutional framework for monetary and fiscal policies as well as for product, labour and financial...
