Abstract
The present study examines the socio-economic consequences of a climate policy-driven coal phase-out in Germany. A focus lies on the lignite industry – especially in the lignite regions. In a first step, the regions are spatially defined and described. Additional analysis is based on energy economic modelling. The model examines phase-out scenarios, which differ in the chosen criteria for the order of power plant closure (specific emissions or plant age). An input-output-model and a regional macroeconomic model build up on these phase-out pathways and examine the socio economic effects of the phase-out in the lignite regions as well as in the rest of Germany. The combination of both models offers the advantage to consider the phase-out from different perspective and hence derive different and more robust effects. The models show, on the one hand, that in an early phase-out the negative effects of structural change are visible earlier. On the other hand, recuperative effects can counteract the negative consequences according to the regional economic model.
Furthermore, the structural change creates economic opportunities. Those opportunities are primarily diversified economic activities. Case studies show significant employment potentials for the lignite regions. New jobs in renewable energies and energetic optimization of buildings can already counteract the negative employment effects associated with the investigated structural change. The study concludes, describing accompanying political instruments that can support the regions on their way to master the challenges of the up-coming structural change.

Fiscal Equalization, Tax Salience, and Tax Competition
Martin Altemeyer-Bartscher
IWH Discussion Papers,
No. 3,
2014
Abstract
Jurisdictions that engage in inter-regional tax competition usually try to attenuate competitive pressures by substituting salient tax instruments with hidden ones. On this effect, we investigate the efficiency consequences of inter-regional tax competition and fiscal equalization in a federal system when taxpayers fail to optimally react on shrouded attributes of local tax policy. If the statuary tax rate is a relatively salient instrument and taxpayers pay low attention to the quality and the frequency of tax enforcement, the underlying substitution of tax instruments with the aim of reducing the perceived tax price may suppress the under-exploitation of tax bases that is typically triggered by fiscal equalization.

Evaluating the German (New Keynesian) Phillips Curve

IWH Discussion Papers,
No. 10,
2008
Abstract
This paper evaluates the New Keynesian Phillips Curve (NKPC) and its hybrid
variant within a limited information framework for Germany. The main interest rests on the average frequency of price re-optimization of firms. We use the labor income share as the driving variable and consider a source of real rigidity by allowing for a fixed firm-specific capital stock. A GMM estimation strategy is employed as well as an identification robust method that is based upon the Anderson-Rubin statistic. We find out that the German Phillips Curve is purely forward looking. Moreover, our point estimates are consistent with the view that firms re-optimize prices every two to three quarters. While these estimates seem plausible from an economic point of view, the uncertainties around these estimates are very large and also consistent with perfect nominal price rigidity where firms never re-optimize prices. This analysis also offers some explanations why previous results for the German NKPC based on GMM differ considerably. First, standard GMM results are very sensitive to the way how orthogonality conditions are formulated. Additionally, model misspecifications may be left undetected by conventional J tests. Taken together, this analysis points out
the need for identification robust methods to get reliable estimates for the NKPC.

Network investment and the threat of regulation: avoiding monopoly or infrastructure extension

Wirtschaft im Wandel,
No. 5,

Abstract
In summer 2005, Deutsche Telekom announced its plans for the buildup of a new fiber glass network. At the same time, it formulated the condition that this network was not to be regulated concerning pricing or use by other providers (network access). In order to make this investment possible, in its coalition treaty the big coalition agreed to exclude the new network from the ex-ante regulation and to include this freedom from regulation in the telecommunication law. The question is now how investments can be facilitated and, at the same time, welfare losses through monopoly gains can be avoided. Applying game theory, it can be shown that a regulation authority like the ‘Bundesnetzagentur’, which is responsible for German telecommunication sector, should signal an increasing tolerance for deviations from its calculated and determined regulatory price in the face of increasing uncertainty concerning expected cost and returns. Thus, the threat of regulation alone leads to tolerable prices, without the actual regulation taking place. In the future, the ‘Bundesnetzagentur’ should reduce information asymmetries and the optimal level of tolerance in order to achieve a more precise intervention price and a more effective threat of regulation. The effectiveness of such a threat decreases if the legislation prevents the regulation authority from using this instrument by law. Against this background, the recent Federal Government resolution from March 17th 2006 noveling the telecommunication law heads for the economically right direction but it has to prove its incentive compatibility in the daily legal practice.

Optimierung der Geldpolitik in Schwellenländern durch einen International-Lender-of-Last-Resort

2006
Abstract
Current currency crises in emerging market economies show the insufficiency of preventive measures on national, regional and international level. The task of the book is therefore to analyze systematically which conditions monetary policy has to fulfill in order to prevent currency crises. In a first step optimal, crises-preventing monetary policy is modeled. Further the chances for overcoming the limitations of national policy are discussed on the regional and international level. The main result of the descriptive, theoretical and econometric analysis is the construction of an instrument for international monetary policy: the International Lender of Last Resort.

Climate protection policy in the housing sector: Lacking impact and need for action
Steffen Hentrich
Wirtschaft im Wandel,
No. 11,
2001
Abstract
Energy savings in the rental housing sector may contribute to the reduction of global greenhouse gas emission. However, emissions have gone up since the early nineties despite of large energy saving potentials. In general the effects of energy saving regulations and support programmes were overestimated. Unfortunately, these programmes ignore market specific restraints.
Markets do not provide optimal incentives to prevent emissions since the costs of greenhouse gas emissions are not fully internalised in fuel prices. Special characteristics of rental housing market in Germany enhance this deficit. Consequently profitable measures of saving energy are neglected. Overall the effectiveness of regulations and support programmes suffers.
Therefore it is necessary to strengthen energy saving incentives. Suitable instruments would include a gradual rise in fuel taxes (Öko-Steuer), a reduction of rental housing market control and measures to improve the transparency of energy consumption.
