Enlarging the EU: How can the costs be minimised?

Enlargement of the EU will be associated with many costs for all participants— the prospective new members, the old memebers and the EU institutions. A strategy should be pursued that reduces the economic costs as far as possible. This implies a postponement of enlargement until the conditions are more favourable. The author would like to thank Prof. El-Shagi El-Shagi and Dr. Dorothea Witter-Rieder for helful comments on an earlier draft of this paper.

Monetary and fiscal policy interactions in a New Keynesian model with capital accumulation and non-Ricardian consumers

The paper examines simple monetary and fiscal policy rules consistent with determinate equilibrium dynamics in the absence of Ricardian equivalence. Under this assumption, government debt turns into a relevant state variable which needs to be accounted for in the analysis of equilibrium dynamics. The key analytical finding is that without explicit reference to the level of government debt it is not possible to infer how strongly the monetary and fiscal instruments should be used to ensure determinate equilibrium dynamics. Specifically, we identify bifurcations associated with threshold values of steady-state debt, leading to qualitative changes in the local determinacy requirements.
