Europäische Klimapolitik: Zwischen Anspruch und Wirklichkeit

In order to restrict the risks of anthropogenic climate change to a ?tolerable“ extent, the fourth assessment report of the United Nations’ International Panel on Climate Change calls for a trend reversal towards globally decreasing greenhouse gas emissions within the next two decades which ultimately must lead to a reduction of carbon dioxide emissions until the mid of the century by 50 percent as compared to 2000 emission levels. The European Union claims a lead of a role in climate policy with the objective to push forward international negotiations on far-reaching emission reduction commitments with other important industrialized and developing regions. The EU’s credibility as a leading force will hinge crucially on how successfully it can fulfill its emission reduction obligations under the Kyoto Protocol by means of market-based environmental policy, in particular the exemplary operation of the EU emission trading system. Against this background, the following article provides a critical assessment of the EU’s climate policy.     

Das leere Versprechen der aktiven Konjunktursteuerung

Since the financial crisis and the ensuing sluggish recovery, a growing number of voices have called for a more active role for fiscal policy to stimulate the economy. We reject this call and argue that in normal times, monetary policy and automatic stabilisers are sufficient to smooth the business cycle. The effectiveness of active fiscal policy is too uncertain and the requirements for a sensible adjustment are too high. Moreover, determining the state of the business cycle is almost impossible in real time. The benefits of active fiscal policy therefore do not outweigh its costs. Only in exceptional situations should policy makers consider active fiscal policy measures as an option.     

Argumente gegen die Reform des Stabilitätsgesetzes wenig überzeugend — eine Replik

In their reply, Dullien and van Treeck criticise the argument of Michaelis, Elstner and Schmidt that the German Stability and Growth law (StabG) from the 1960s must not be reformed. They claim that Michaelis et al. neglect that the concept of sustainability has changed over the past 50 years and that nowadays issues such as social and ecological sustainability should be included. Moreover, the claim by Michaelis et al. that the StabG provides important tools for business cycle management is hardly convincing, given that these tools have not been used since the 1970s and stimulus packages have been passed on other legal grounds. / In their response Michaelis et al. stress that economic policy has to consider equally aspects of economic, social and ecological sustainability. The StabG, however, is a completely inappropriate basis for attempts to address aspects of social and ecological sustainability. The main use of the StabG consists in the possibility to quickly implement fiscal measures that could mitigate the consequences of severe economic downturns. Proposals of Dullien and van Treeck that various dimensions of sustainability are controllable by a predetermined set of instruments neglect the complexity of the social market economy.     

Economic crises in the thirties and today

In the context of the ongoing financial and economic crisis reference is frequently made to the Great Depression of the 1930s and fears are voiced that we may have embarked on a similar path. This article looks at the conditions prevailing back then and compares them with the present economic environment. From this some conclusions are drawn as to the likelihood of a recurrence of the disaster.     

Welfare effects of the euro cash changeover

Using merged data from the British Household Panel Survey (BHPS) and the German Socio-Economic Panel (SOEP), this paper applies a parametric difference-in-differences approach to assess the real effects of the introduction of the euro on subjective well-being. A complementary nonparametric approach is also used to analyze the impact of difficulties with the new currency on well-being. The results indicate a loss in well-being associated with the introduction of the new currency, with the predicted probability that a person is contented with his/her household income diminishing by 9.7 percentage points. We calculate a compensating income variation of approximately one-third. That is, an increase in post-government household income of more than 30% is needed to compensate for the clear decline in well-being. The reasons for the negative impact are threefold. First, perceived inflation overestimates the real increase in prices resulting in suboptimal consumption decisions. Second, money illusion causes a false assessment of the budget constraint. Third, individuals have to bear the costs from the conversion and the adjustment to the new currency. Moreover, it is thought that losses are higher for persons who have difficulties with the new currency. However, the impact of difficulties in using and converting the new currency is rather small, and the initial problems were overcome within one year of the introduction of euro cash.     

Energiesparen: Warum wird Beratung gefördert?

Home renovation is generally asserted to be a highly effective means to increase residential energy efficiency and thereby contribute to climate protection from reduced energy consumption. As part of a larger package of measures in the residential sector, the German government is consequently providing financial support for home audits from recognized energy experts who provide advice on retrofitting options. To date, the question concerning the effectiveness these home audits has largely escaped empirical scrutiny. The present paper fills this void by providing evidence for considerable free-rider effects within the home audit program, yielding serious reservations with respect to both the effectiveness of the program and its fiscal costs. Moreover, given the substantial differences between the gross- and net effects of home audits that are revealed by this analysis, the program’s contribution to climate protection and thereby the central justification for the associated government outlays is called into question. The social benefit of the program emerges only from those retrofits that would not have been undertaken in the absence of the home audit.     

Disentangling Alliance Management Processes: Decision Making, Politicality, and Alliance Performance

abstract    Using a sample of 106 organizations engaged in strategic alliances, we develop and test a framework of alliance-related organizational decision-making processes and their impact on alliance performance. With regard to direct effects, our results show a negative impact of decision-making recursiveness and no significant relationship for openness and procedural rationality. Acknowledging the importance of the organization's micropolitical context in which these decision processes are embedded, we also test the moderating influence of politicality. Our findings provide support for our hypotheses that in a context of low politicality, the decision-making characteristics of openness and procedural rationality have a positive influence, whereas recursiveness negatively affects alliance performance. In a context of high politicality, however, openness and procedural rationality exert a negative influence, and the negative impact of recursiveness is aggravated. We suggest that alliance-related decision making cannot be adequately understood without explicitly considering the micropolitical context in organizations.
