Teacher shortages, teacher contracts and their effect on education in Africa

Summary.  To enhance primary enrolment rates, many African countries have launched large teacher recruitment programmes in recent years. Given tight budgetary constraints, teachers are no longer employed in civil service positions, but on the basis of (fixed term) contracts typically implying considerably lower salaries and a sharply reduced amount of professional training. We analyse the effect of this change on educational quality in Niger, Togo and Mali, on the basis of very informative data, which are comparable across these countries. We use a variety of estimation techniques, including a non-parametric estimation of quantile treatment effects. Our results demonstrate that contract teachers tend to reduce inequalities in student outcomes. Overall, the effects are positive in Mali, somewhat mixed in Togo and negative in Niger. This ordering is consistent with theoretical expectations related to the manner in which contract teacher programmes were implemented differently in each of the three countries under study.

Labor Schweiz: Vergleichende Wahlbeteiligungsforschung bei Kantonalen Parlamentswahlen

How to explain different levels in voting turnout among the Swiss sub-national units? To answer this question, this study presents the first comparative and macro-quantitative investigation of the voting participation in parliamentary elections of the Swiss Cantons between 1982 und 2004. The paper evaluates political institutions, socio-economic factors, and cultural foundations. According to our statistical inquiry we present four main determinants of cross-cantonal variance in voting turnout: mandatory voting laws, electoral thresholds, the coverage of partisan membership, and a culture of Catholicism. Moreover, the estimations reveal that there is no systematic influence of patterns of direct democracy on the voting participation in parliamentary cantonal elections.     

Bubbles and Crashes

We present a model in which an asset bubble can persist despite the presence of rational arbitrageurs. The resilience of the bubble stems from the inability of arbitrageurs to temporarily coordinate their selling strategies. This synchronization problem together with the individual incentive to time the market results in the persistence of bubbles over a substantial period. Since the derived trading equilibrium is unique, our model rationalizes the existence of bubbles in a strong sense. The model also provides a natural setting in which news events, by enabling synchronization, can have a disproportionate impact relative to their intrinsic informational content.     

The governance of free/open source software projects: monolithic, multidimensional, or configurational?

This paper presents the results of a qualitative review and synthesis of the literature on open source governance, addressing four key questions: (1) How has open source software (OSS) governance been defined? (2) Has the phenomenon of OSS governance been conceptualized as a monolithic or multidimensional phenomenon? (3) What purposes is OSS governance hypothesized to serve? and (4) What are the dimensions of OSS governance, and how are these dimensions related to each other? The results of the review suggest a framework for future comparative and case study research on OSS governance, and they provide a basis for comparison with research on the governance of other distributed, community-based forms of content and creation.     

University–industry relationships and open innovation: Towards a research agenda

Organizations increasingly rely on external sources of innovation via inter‐organizational network relationships. This paper explores the diffusion and characteristics of collaborative relationships between universities and industry, and develops a research agenda informed by an ‘open innovation’ perspective. A framework is proposed, distinguishing university–industry relationships from other mechanisms such as technology transfer or human mobility. On the basis of the existing body of research, the role of practices such as collaborative research, university–industry research centres, contract research and academic consulting is analysed. The evidence suggests that such university–industry relationships are widely practised, whereby differences exist across industries and scientific disciplines. While most existing research focuses on the effects of university–industry links on innovation‐specific variables such as patents or firm innovativeness, the organizational dynamics of these relationships remain under‐researched. A detailed research agenda addresses research needs in two main areas: search and match processes between universities and firms, and the organization and management of collaborative relationships.     

Cross-border mergers and the cross-border effect: the case of the automotive supply industry

In this paper we examine stock price reactions to cross-border mergers and acquisitions in a particular industry, the automotive supply industry. We show that cross-border transactions entail a pronounced value creation for the acquiring shareholders and that this value creation also holds for transcontinental transactions, which to our knowledge have not been investigated so far. Splitting the sample by different types of targets indicates that the value creation mainly stems from takeovers of subsidiaries. By examining differences between national and international takeovers in cross-section, we sustain the recent evidence of a negative cross-border effect (i.e., cross-border mergers and acquisitions entail lower announcement returns than national ones).

Globale ökonomische Eliten? Eine Globalisierungsthese auf dem Prüfstand der Empirie

Does globalization lead to global markets for managers and international careers? The hypothesis of the globalization literature, that a transnational management is emerging out of a global “war of talents” is examinded by using data on the migration of managers from the U.S., East Asia and Germany. The data show, that no significant brain drain between these countries is taking place and “brain circulation” of insiders with short-term stays abroad is the dominant career pattern. The less likely the exchange of an installed CEO, the more career systems are used for status achievement by Clans and the stronger the influence of informal cultural rules, the higher is the rate of insiders. Thus, between the U.S., Germany and East Asia no significant global markets for managers are evolving.
