K?nnen sich erneuerbare Energien langfristig auf wettbewerblich organisierten Stromm?rkten finanzieren?

In this paper we address the issue of whether renewable energy sources can be integrated into power markets if the use of renewable energies is extended at the desired speed. Market integration means that renewable energy sources have to cover their full costs from revenues on competitive markets. In the first part of this paper, we evaluate the long-term revenues of intermittent renewable energy sources using a high resolution power market model. Considering the renewable targets of the German lead study of 2010, we show that due to the merit order effect, intermittent renewable energy sources, such as wind power and photovoltaic, cannot be financed through power markets alone, even if their full costs fall below those of conventional power plants. This is also true for scenarios with high CO₂-prices and increasing spot market prices. In the second part of this paper, we discuss whether in the long run additional instruments such as green certificates or capacity markets would allow for a more competitive financing of renewable energy sources. Center stage in the discussion is the question under which circumstances these instruments increase competitive pricing and decentralised market decisions.     

Experten im Einsatz

Zusammenfasung  Task Force „Barrier Nursing“ — Krankheitserreger machen vor L?ndergrenzen keinen Halt. Dies ist sp?testens seit der Vogelgrippe bekannt. Da Soldaten durch ihre weltweiten Eins?tze besonderen Gesundheitsgefahren ausgesetzt sind, ist bei der Bundeswehr schnelles Handeln gefragt, wenn es um Infektionen wie die durch Ebola-, Pocken- oder Lassavirus hervorgerufenen Erkrankungen geht.     

Kundenportale in der Energiebranche: Bestandsaufnahme und Entwicklungspotenziale

Since the energy market had been liberalized, the competition between utilities has increased. In order to win new and hold existing customers, it seems necessary to develop new services and products that closely meet the needs of the customers. An online-portal can be such a service, as it will serve as a central interface between utility and customer when the personal contact diminishes due to a decreasing local focus of the utility and the omission of the meter reading at the customer’s house caused by Smart Metering. In this article, the major criteria for the development of such a portal will be introduced. A market survey shows which criteria are already considered and which design criteria are not taken into account yet. This article focuses psychological concepts that motivate customers to use the portal regularly and save energy. We conclude that there is much room for improvement with regard to the criteria that are meant to illustrate the energy consumption and with regard to the provision of psychological incentives.     

Wealth and Income Inequality in Europe

While it has long been apparent that global levels of wealth and income inequality have been steadily increasing since the 1970s, the issue received scant attention in Europe until the recent fi nancial crisis and the resulting Great Recession illuminated for the general public just how great the chasm between the very rich and everybody else had grown. This realisation was coupled with an increased focus on inequality among economists and other academics, leading to a fresh drive for policy ideas to remedy the alarming trend. This Forum comprises a diverse range of viewpoints on the recent history and dynamics of inequality within Europe, each striving to defi ne the root causes in the various countries being examined. The defi nition of these causes, of course, can inform the direction of policies aimed at alleviating the growing inequality in many European countries and thereby curtail one of the major political and social issues of our time.     

New Tools in Comparative Political Economy: The Database of Political Institutions

This article introduces a large new cross-country database,the Database of Political Institutions. It covers 177 countriesover 21 years, 1975–95. The article presents the intuition,construction, and definitions of the different variables. Amongthe novel variables introduced are several measures of checksand balances, tenure and stability, identification of partyaffiliation with government or opposition, and fragmentationof opposition and government parties in the legislature.     

A New Database on the Structure and Development of the Financial Sector

This article introduces a new database of indicators of financialstructure and financial development across countries and overtime. The database is unique in that it combines a wide varietyof indicators that measure the size, activity, and efficiencyof financial intermediaries and markets. It improves on previousefforts by presenting data on the public share of commercialbanks, introducing indicators of the size and activity of nonbankfinancial institutions, and constructing measures of the sizeof bond and primary equity markets.     

When arm's length is too far: Relationship banking over the credit cycle

We conduct face-to-face interviews with bank chief executive officers to classify 397 banks across 21 countries as relationship or transaction lenders. We then use the geographic coordinates of these banks’ branches and of 14,100 businesses to analyze how the lending techniques of banks near firms are related to credit constraints at two contrasting points of the credit cycle. We find that while relationship lending is not associated with credit constraints during a credit boom, it alleviates such constraints during a downturn. This positive role of relationship lending is stronger for small and opaque firms and in regions with a more severe economic downturn. Moreover, relationship lending mitigates the impact of a downturn on firm growth and does not constitute evergreening of loans.     

Tarifpartnerschaft — ein altes,aber gefährdetes Bündnis?

100 years ago, in November 1918, the Stinnes Legien Agreement was drawn up between various employers’ associations and trade unions. It included collective bargaining autonomy and collective agreements, the eight-hour work day and work councils. It soon failed, but served as a model for the legal regulation of collective bargaining relations after the Second World War. In the meantime, however, collective bargaining has declined significantly. Many employers are members of their associations without a collective agreement. At the same time, union memberships are declining. In view of increasingly precarious forms of employment, the government apparently needs to implement stronger regulations on collective bargaining relations again, such as the Minimum Wage Act. Finally, a look back: In 1918, editorial member Alfred Schmidt-Essen commented on the agreement from a current perspective. We document the article.
