This paper econometrically estimates residential water consumption in Germany between 2007 and 2013 based on a panel of almost 3000 supply areas. In particular, the analysis distinguishes periods of rising and falling water and sewage water prices. The short-run (long-run) price elasticity is estimated at around 4.2% (13%), but water demand appears to respond asymmetrically to rising and falling prices. When prices are rising, the short-run (long-run) price elasticity is around 6.5% (17%). When prices are falling, the short-run price elasticity is not statistically different from zero, and the long-run price elasticity is estimated at around 12%. Additional results illustrate that employing average prices instead of marginal prices results in substantially overestimating the price elasticity. These findings are particularly relevant for utilities and regulators planning to alter the tariff structure towards a higher fixed fee and a lower volumetric fee. 相似文献

This article presents the outcomes of an evaluation of the impact of the series of mergers of the local exchange companies that have taken place between 1988 and 2001 on an important measure of performance of the firms undergoing the mergers. The analysis reveals that after firms have undertaken one merger they experience little or no growth after such mergers, but the impact of second mergers on firm growth have been negative. If an important motive in undertaking mergers has been to enhance firm growth, then the merger waves that have been approved and consummated have led to performance declines. The impacts of the merger wave on the growth of the telecommunications sector firms have been negative. 相似文献

In order to assess the growth implications of policy complementarities, this paper applies second‐best results to reform indicators. During the transition from central planning to EU integration, which corresponds to a policy cycle, a complementarity index based on structural indicators compiled by the European Bank for Reconstruction and Development (EBRD) decreases and then increases while the level of reforms tends to rise throughout. Corrected for initial conditions, the extent of macroeconomic stabilization and endogeneity, the level of reforms and changes in their complementarity are found to be positively related to output growth. The study uses panel data for 27 countries between 1989 and 2004. 相似文献
