Growth Effects of Fiscal Policy and Debt Sustainability in the EU

In this paper we study the relationship of fiscal policy and economicperformance of some core countries in the EU. Our aim is to find outwhether public deficit and public debt have consequences for real variables in the economies we consider. The background of our empirical study is a growth model that provides us with some predictions on the relationship between fiscal policy and economic growth. In a first step we then use Granger causality tests to analyze empirically whether some of the implications of our model arecompatible with the data. In a second step, we investigate whether the fiscalpolicies of the member states have been sustainable. Given this information,we then pursue the question of whether differences in the fiscal positions ofcountries have consequences as concerns the outcome of our empirical testsof step one. Finally, we study whether the impact of the public deficit ratiodepends on the magnitude of the debt ratio.     

Creditworthiness and thresholds in a credit market model with multiple equilibria

Summary. The paper studies creditworthiness in a model with endogenous credit cost and debt constraints. Such a model can give rise to multiple candidates for steady state equilibria. We use new analytical techniques such as dynamic programming (DP) with flexible grid size to find solutions and to locate thresholds that separate different domains of attraction. More specifically, we (1) compute present value borrowing constraints and thus creditworthiness, (2) locate thresholds where the dynamics separate to different domains of attraction, (3) show jumps in the decision variable, (4) distinguish between optimal and non-optimal steady states, (5) demonstrate how creditworthiness and thresholds change with change of the credit cost function of the debtor and (6) explore the impact of debt ceilings and consumption paths on creditworthiness.JEL Classification Numbers: C61, C63, D91, D92, E51, G12, G32.An earlier version of this paper has been prepared for the 1998 North American Winter Meeting of the Econometric Society, January 1998, Chicago.
