The European Union’s Constitutional Crisis—Causes and Consequences

The rejection of the treaty establishing a European constitution by French and Dutch voters has thrown the EU into a deep crisis. What developments in the EU contributed to these referenda results? What consequences are to be drawn for the continuation of integration and the integration goal, the governance of the EU-25 and the further planned enlargements? What flaws are there in the present draft constitution and how can these be dealt with?     

Empirical Evaluation of Fair Use Flat Rate Strategies for Mobile Internet

The fair use flat rate is a promising tariff concept for the mobile telecommunication industry. Similar to classical flat rates it allows unlimited usage at a fixed monthly fee. Contrary to classical flat rates it limits the access speed once a certain usage threshold is exceeded. Due to the current global roll-out of the LTE (Long Term Evolution) technology and the related economic changes for telecommunication providers, the application of fair use flat rates needs a reassessment. We therefore propose a simulation model to evaluate different pricing strategies and their contribution margin impact. The key input element of the model is provided by so-called discrete choice experiments that allow the estimation of customer preferences.     

Beschäftigungswachstum durch effizientere Allokation auf dem Arbeitsmarkt

Die positive Entwicklung des deutschen Arbeitsmarkts führt zu einer zunehmenden Diskussion über die Qualit?t des Besch?ftigungsaufbaus. Kritiker beanstanden die Zunahme flexibler Besch?ftigungsformen und fordern mehr Regulierung. Aus ?konomischer Sicht würde die Wiedereinschr?nkung der in den vergangenen Jahren hinzugewonnenen ?ffnungsspielr?ume die Allokationsfunktion des Arbeitsmarkts schw?chen. Dabei l?sst sich der Besch?ftigungsaufbau wesentlich auf die Arbeitsmarktreformen der letzten Jahre zurückführen. Durch flexible Besch?ftigungsformen und eine besch?ftigungsorientierte Tarifpolitik wurden die Wettbewerbselemente des Arbeitsmarkts gest?rkt.     

Was ist von der Familienpolitik der Großen Koalition zu erwarten?

A major evaluation of family policies in Germany came to the primary conclusions that family leave and early childhood education and care policies are effective. Specific German tax regulations, however, are less effective, as they decrease the incentives, especially for mothers, to return to the labour market or increase the number of hours they work. The tax regulations for couples, in particular, should be reformed, as this would offer funding possibilities for other worthwhile policies. However, it should not be forgotten that tax regulations are not just aimed at family policies. Indeed, their primary function is to reduce the burden on families and to keep them out of poverty, as demanded by the Germany Federal Constitutional Court. Given the findings of this evaluation, the new German government plans to implement policies which make sense but which do not go far enough. Public child care has been shown to increase maternal employment, household income and fertility in Germany. There are good reasons to invest further in public child care for young children; however, the focus should not only be on the quantity but also the quality of care.     

Gesundheitsfonds — effizientere Steuerung des Gesundheitssystems?

In 2009 the German central health fund was implemented. It was the result of a political compromise. One political party intended to equalise the risk structure among 130 different health care funds, and the other wanted to intensify competition and to improve efficiency among the different health insurances. The fund is flanked by a health-based risk adjustment and is aimed at sustainably ensuring the funding of the statutory health insurance system. It also constitutes the basis for competition among statutory health care funds, securing quality and efficiency in health care provision. To cover additional expenditures, health insurers had to charge flatrate premiums. A new law, which will come into effect in January 2015, will oblige health insurers to charge income related contributions. It is not clear how this will change competition among insurers. The federal government will not need to finance subsidies to low income individuals anymore. Income redistribution will only take place within the public health insurance system, exempting the privately insured and public servants from supporting low income individuals. The authors claim that the health care fund will not succeed in its aim of securing a sustainable financial basis for the statutory health insurance system. Most of the authors argue that there is no evidence of greater efficiency thus far, and they offer proposals on how to achieve improved performance.     

Inequality, Crime and Economic Growth. A Classical Argument for Distributional Equality

This paper studies the dynamic general-equilibrium interactions between inequality, crime and economic growth by embedding the rational choice-theoretical approach to criminal behavior in a heterogeneous-agents endogenous-growth OLG model. Based on their respective opportunity costs, individuals choose to specialize in either legal or criminal activities. While legal households contribute to aggregate goods supply over time by either working or building human capital, criminals make a living by expropriating legal citizens of part of the latter's income. An increase in inequality lowers the economy's growth rate and possesses negative welfare effects for all agents with endowments equal to or above average and for agents with endowment below average that are born sufficiently far in the future.     

Management Roles and Sustainability Information. Exploring Corporate Practice

Little empirical research has been conducted on perceptions of the types of sustainability information dealt with by different managers in internal company processes. In this study the roles of different managers are distinguished based on contingency theory and using the categorisation in the sustainability balanced scorecard concept. Expected sustainability information types are identified for these roles and hypotheses are derived and tested about perceptions of the types of sustainability information in different management roles. Interviews identified 116 roles involved with sustainability information in a set of leading German and UK sustainability reporting companies. Results from analysing sustainability information types contingent upon different management roles contribute to the understanding of sustainability accounting systems and practices and how companies can best support different management roles with appropriate sustainability information.
