10 Years of natural gas sector regulation in Germany — With special focus on self regulation through association agreements („Verbändevereinbarungen“)

This paper gives a survey of natural gas sector regulation in Germany over the past decade. We trace the origins of the debate at the time of the Germany Energy Law of 1998, up to January 2009 when incentive regulation will begin. The focus of the paper is a strategic analysis of the Association Agreements (“Verbändevereinbarungen”), a peculiar German Sonderweg of corporate self-regulation, leading to welfare losses. We argue that self-regulation was the wrong way to approach sectoral reform, and that (incentive) regulation is the adequate framework for natural gas transmission.     

Determinanten der Strom-und Gaspreisentwicklung in Deutschland — Eine empirische Bestandsaufnahme für die Jahre 1998 bis 2007

The price worthy supply of energy is an indispensable requirement for growth and employment in highly industrialized countries as Germany. For energy intensive production processes — with limited opportunities to accomplish efficiency gains or substitute fuel — energy prices and costs are important determinants for competitiveness. But the other manufacturing sectors and households too, are affected by these high energy costs respectively expenditures, which result in real production losses or correspondingly in cutting back expenditures for non-energetic consumer goods. In view of the strongly increased level of energy prices — the price for crude oil hit the historic peak of $121 per barrel in May 2008 — especially grid bound energy sources as electricity and gas are in focus of the public. A recent study of the EEFA research institute illustrates the determinants of the development of electricity and gas prices in Germany from 1998 to 2007.

What really matters: Discounting, technological change and sustainable climate

This paper discusses the interplay between the choice of the discount rate, greenhouse gas mitigation and endogenous technological change. Neglecting the issue of uncertainty it is shown that the Green Golden Rule stock of atmospheric carbon is uniquely determined, but is not affected by technological change. More generally it is shown analytically within the framework of a reduced model of integrated assessment that the optimal stationary stocks of atmospheric carbon depend on the choice of the discount rate, but are independent of the stock of technological knowledge. These results are then reinforced numerically in a fully specified integrated assessment analysis.     

Struktureller Wandel und Krisenbewältigung der deutschen Volkswirtschaft

Die Wirtschafts- und Finanzkrise wirkt wie ein externer Schock auf die deutsche Konjunktur. Mit zwei makro?konomischen Simulationsmodellen weisen die Autoren nach, dass die Krise in Deutschland allein auf diesen Schock zurückzuführen ist. Die Exportabh?ngigkeit der Wirtschaft führt dazu, dass die Produktion zunehmend volatiler wird. Demgegenüber hat sich die Besch?ftigungsentwicklung stabilisiert und von der Konjunktur abgekoppelt — vor allem dank der staatlichen Hilfen.     

Temporary layoff unemployment in Austria: empirical evidence from administrative data

Temporary layoffs (rehires, recalls) have been widely recognized as an important feature of North America's labour markets. For Europe, however, several observers have suggested that tighter regulatory impediments to the recruitment and dismissal of employees are responsible for temporary layoff unemployment being virtually non-existent. Against this background this paper uses administrative data to evaluate the quantitative importance of temporary separations among the unemployed in Austria and to track its composition by industries. The main finding of our empirical analysis is that about one-third of all unemployment spells in Austria in 1985 ended with the individual returning to the former employer. Since temporary layoff unemployment was found to be on average of shoter duration, it comprised a somewhat lower fraction of total weeks of unemployment. However, temporary layoff unemployment thus accounts for the same proportion of unemployment in Austria as in the US or Canada.
