Ist der Fahrplan der Energiewende noch einzuhalten?

The German energy transition represents a policy-driven, sustainability-oriented restructuring of both supply- and demand-side components of the entire energy system by 2050. Whereas the development of renewable energies in the electricity sector is right on track, due to the feed-in tariffs of the German Renewable Energy Sources Act, many other crucial requirements for a successful transition are not, amongst others the improvement of energy effi ciency and the decarbonisation of the transport sector. Contrary to the public discussion, the primary future challenges do not consist in limiting electricity prices or abandoning feed-in support schemes, but rather in coordinating the variety of actors as well as appropriately matching the different system elements (grids, technologies, energy sectors, demand and supply side, etc.). Much remains to be done. By highlighting some examples like the need to take into account future implications of climate change for the energy sector, the consequences of the current crisis in the European Union’s emissions trading scheme and the need for a cautious adjustment of the EEG, the paper argues that the major challenges regarding the German energy transition mainly go beyond the current policy-driven and short-term discussion of energy prices. Germany’s pioneering attempt to integrate steadily increasing share of non-dispatchable electricity from renewable sources is challenging the stability of the system. Several characteristics in the current selfregulating system are identifi ed and analysed, which reveal themselves as potential weaknesses or shortcomings in the upcoming system.     

Talking by numbers — Communicated uncertainty of the ECB

Using a novel approach, this paper analyses the deliberately communicated uncertainty of the ECB to the market. Specifi cally, it semantically analyses the uncertainty expressed in offi cial ECB press statements. The analysis shows how the ECB tries to alert or appease the market with different levels of communicated uncertainty. The appeasement through low uncertainty communication levels is particularly pronounced during times of fi nancial distress. Further, the analysis shows that the ECB tried to alert the market through an increasing level of communicated uncertainty prior to the outbreak of the global fi nancial crisis.     

The origins and evolution of democracy: an exercise in history from a constitutional economics approach

In this article the conditions for the rise and fall of representative regimes are explored. High citizen mobility and unexploited opportunities for investment create the need of reassuring factor owners against the tax hunger of the State. This may lead to the emergence of representative institutions of government, a process that reverts when those conditions disappear. Factors that facilitate or restrain the mobility of citizenry are identified, mainly in the domain of military technology. Thus, a number of interrelations between production and war technologies, political development and economic performance are revealed, giving rise to an interpretation of historical evolution.

The effect of international staffing practices on subsidiary staff retention in multinational corporations

This paper contributes to the scarce body of research on employee turnover in multinational corporations' foreign subsidiaries and addresses some key issues related to dealing with turnover of local staff. Based on a literature review, I conceptualize locals' perceived career prospects and their organizational identification as key variables mediating the relationship between international staffing practices and local staff turnover. In a second step, the paper develops instruments that help international firms to retain their subsidiary staff. Specifically, I focus on how international staffing practices need to be configured to ensure employee retention and I derive moderating factors. My arguments are integrated into a framework for the effect of international staffing practices on subsidiary staff retention in multinational corporations.     

On the relationship between supplier integration and time-to-market

Recent operations management and innovation management research emphasizes the importance of supplier integration. However, the empirical results as to the relationship between supplier integration and time-to-market are ambivalent. To understand this important relationship, we incorporate two major recent developments. First, the literature has started to redefine supplier integration into two dimensions, supplier product integration and supplier process integration. Second, recent research has begun to examine spillover effects that extend beyond the direct costs and benefits of the supplier contract. Using survey data of 116 firms in the industrials, health care, and information technology industries, the results confirm our hypotheses and show that supplier product integration decelerates time-to-market while supplier process integration accelerates time-to-market. The results also show a positive relationship between supplier integration and the adoption of external technologies, which either decelerates or accelerates time-to-market depending on the level of internal exploration activities. Our research, thus, helps to open the ‘black-box’ of the relationship between supplier integration and time-to-market, and provides a theoretically grounded explanation to the apparent contradictory results in prior research about the influence of supplier integration on time-to-market. In addition, we contribute to research on spillover effects by emphasizing that information technology adoption and assimilation is an important spillover effect of supplier integration.     

Marketingerfolg richtig messen: Optimale Kennzahlensysteme

Zusammenfassung  Wie kann man zuverl?ssige Methoden entwickeln, um die Erfolgswirkungen von Marketingma?nahmen auf den Unternehmenswert zu messen? Am Anfang steht dabei die Frage, was Marketingerfolg eigentlich ist. Eine reine Fokussierung auf die Stakeholdergruppe der Kunden reicht hier nicht aus. Andere, durch Marketing ebenfalls erreichte Interessensgruppen wie z.B. Investoren oder Mitarbeiter müssen auch betrachtet werden. Und das alles vor dem Hintergrund moderierender Kontextfaktoren wie etwa der Unternehmensstrategie oder der Branche. Dipl.-Kfm.

Experimental investigation of stationary concepts in cyclic duopoly games

We experimentally test the predictive success of three stationary concepts in two cyclic duopoly games. The concepts are Nash equilibrium, impulse-balance equilibrium and payoff-sampling equilibrium. In the experiment 11 independent subject groups, consisting out of six participants interacting over 200 rounds, were gathered for each game. The comparison of the three concepts with mixed strategies shows that the order of performance from best to worst is as follows: payoff-sampling equilibrium, impulse-balance equilibrium, and Nash equilibrium. In addition the data exhibit a weak but significant tendency over time in the direction of coordination at a pure strategy equilibrium.

Debt Relief and the Current Account: An Analysis of the HIPC Initiative

In this paper I develop a model to investigate the connection between debt relief and current account sustainability. This model can be used as a key input in assessing whether a HIPC country's real exchange rate is ‘overvalued,’ and will thus need to go through devaluation. The working of the model is illustrated for the case of Nicaragua, a country that in 2002 had one of the highest external debt to GDP ratios: almost 300 per cent. Nicaragua is the second poorest country in the Western Hemisphere (after Haiti), and for the last decade has relied very heavily on foreign assistance and aid. Moreover, in the last few years Nicaragua has run extremely large current account deficits in excess of 37 per cent of GDP during 1997‐2001 largely financed by grants, donations and migrant remittances.     

Ein simulationsbasierter Renditevergleich von fondsgebundenen Altersvorsorgeprodukten

The demographic change and its consequences forces citizens of Germany to realign towards private insurance products. This decision should be based on structured analyses. Most recent studies were inconclusive regarding this decision.As investments are commonly compared using average developments of the underlying, the possibility to switch the underlying during the duration of the investment, they are not represented accordingly and therefore bias the results of the calculation. We perform a thorough simulation analysis to compare two competing investments for retirement provisions while respecting additional costs and tax implications of switching.Without any switching the evaluation of other studies is generally verified (pure investment beats insurance product). But as soon as switching is implemented the tax advantage of insurance products is overcompensating the cost advantage of a pure investment solution. Further research should aim in this direction.
