Network Access Charges, Vertical Integration, and Property Rights Structure

Abstract
After the deregulation of the German electricity markets in 1998, the German government opted for a regulatory regime called negotiated third party access, which would be subject to ex post control by the federal cartel office. Network access charges for new competitors are based on contractual arrangements between energy producers and industrial consumers. As the electricity networks are incontestable natural monopolies, the local and regional network operators are able to set (monopolistic) charges at their own discretion, limited only by their concerns over possible interference by the federal cartel office (Bundeskartellamt). In this paper we analyse if there is evidence for varying charging behaviour depending on a supplier`s economic independence (structure of property rights) or its level of vertical integration. For this purpose we hypothesise that incorporated and vertically integrated suppliers set different charges than independent utility companies. Multivariate estimations show a relation between network access charges and the network operator’s economic independence as well as level of vertical integration. On the low voltage level, for an estimated annual consumption of 1700 kW/h, vertically integrated firms set – as predicted by our hypothesis - significantly lower access charges than vertically separated suppliers, whereas incorporated network operators charge significantly higher charges compared to independent suppliers. There is insufficient evidence available to confirm these results for other consumptions or voltage levels.

Possible effects of demographic change - An overview

No. 15,
2002
Abstract
One of the more important influences shaping the future economic conditions of the highly industrialized countries is the decline and aging of their population. The article is a comprehensive survey of the impact of this development on key economic variables and the institutions of the welfare state. While the overall consequence of the aging process on productivity growth is more likely to be negative, there are also some offsetting forces like the increase in the capital intensity. The institutions of the welfare state, which are based on intergenerational transfers, will have to be reformed, in order to bring them in line with the demographic process. The prediction of a decrease in the rate of unemployment as a consequence of a declining labor force is according to our analysis not justified.

Are the Central and Eastern European Transition Countries still vullnerable to an Financial Crisis? Results from the Signals Approach
Axel Brüggemann, Thomas Linne

No. 157,

Abstract
The aim of the paper is to analyse the vulnerability of the Central and Eastern European accession countries to the EU as well as that of Turkey and Russia to a financial crisis. Our methodology is an extension of the signals approach. We develop a composite indicator to measure the evolution of the risk potential in each country. Our findings show that crises in Central and Eastern Europe are caused by much the usual suspects as in others emerging markets. In particular an overvalued exchange rate, weak exports and dwindling currency reserves have good predictive power for assessing crisis vulnerabilities.

Effects of the new vote weighting system at EU Council of Ministers on structural fond resources for new members

2001
Abstract
At the recent Nice summit, the EU council of ministers decided on institutional adjustments for the European Union. Such reforms are of particular importance for an enlarged European Union in which up to 27 new members could participate. Amongst the reforms, two decisive changes concern the distribution of votes in an enlarged council and additional conditions which will be attached to majority decisions.
This redistribution of power within the council will effect in particular economic issues, as e.g. the size and distribution of structural funds budgets to be expected upon admittance as EU-member states. Such effects can be estimated by use of models of probability of coalition-building. The model used here predicts that the budget for structural funds for the ten accession countries will be lower than would have been under the old voting power regime. This highlights that the accession group in Central East Europe lost relative voting power via coalitions in comparison to the voting regime prior to Nice. Solely Poland enjoyed an increase in voting power which also suggests an increase in budgets Poland can now expect to receive in the framework of EU structural funds policy.

Incentive effects of unemployment benefits on job searches
Hilmar Schneider, Olaf Fuchs

Abstract
Economic theory predicts that an anticipated cut of the replacement ratio in the future affects the search intensity at all dates previous to the cut. This effect is illustrated by simulating the dynamics of the reservation wage for different time profiles of the replacement ratio with a simple calibrated search model.
