A global energy network? The expansion and integration of non‐triad national oil companies

It is widely perceived that the rising influence of state‐owned energy companies from outside the traditional triad (USA, EU, Japan) is transforming the structure of the global energy market and generating a new wave of resource‐nationalism. There is, however, little empirical analysis of how this process has unfolded. Addressing this empirical gap, in this article I employ a longitudinal social network analysis of the changing corporate relations of five major non‐triad state‐owned energy companies in the period 1997–2007. The findings indicate that, in terms of corporate relations, alongside the global expansion of the non‐triad state‐owned energy companies, there was also an increased integration between them and the private energy companies during this decade. This implies that apart from the resurgence of resource‐nationalism – frequently highlighted in academia and politics – this period also witnessed an increasing transnationalization of the global energy market.     

Schließung von Schulen — Chancen für schulische Innovationsprozesse

Closing down schools — chances of scholar innovative processes. Coaching as support of merging processesThe author discusses chances and risks of processes of school merging processes as an internal coach of a school board. Conditions for success are named for various levels of hierarchy in the school system. This includes an support by means of coaching and supervision.     

ASYMMETRIC SUBSTITUTABILITY: THEORY AND SOME APPLICATIONS

Economists usually describe goods as being either (gross) complements or (gross) substitutes. Yet, what is less known is that one good may be a gross substitute for a second good, while the second good is a gross complement to the first good. This article develops a theory of asymmetric gross substitutability and suggests some potential examples and applications. ( JEL D11)     

RENT‐SEEKING AND CAPITAL ACCUMULATION

A general model incorporating rent‐seeking activities in the standard neoclassical model of capital accumulation is presented. The welfare of the representative agent is negatively affected by the efficiency of rent‐seeking activities. Although intuitive, this result is not obvious because long‐run income can be positively affected by more efficient rent‐seeking activities. The model is used to provide explanations for some recent experiences in developing countries, including the relative poor performance of economies that experience a move to a more decentralized system and the observed path of total factor productivity (TFP) in countries like Ireland and Venezuela.

Permanent liminality: The impact of non‐standard forms of employment on workers' committees in Israel

Workers' committees in Israel are adapting to the neoliberal economy, and the resulting changes in the labour market, by increasingly accepting various non‐standard forms of employment. At the same time, however, they are resisting this reconfiguration of the capitalist economy, in an effort to safeguard workers' rights. Torn between the two positions, workers' committees find themselves in a state of permanent “liminality”, their role reduced to merely seeking compromises and ad hoc solutions. As a result, opposition to the adverse effects of non‐standard employment remains localized and fragmented, thereby consolidating such employment arrangements.     

Computing Probabilities of Type I Error and Type II Error of Sequential Bayesian Procedures for Testing One-Sided Hypotheses

In this article, it is shown how to compute, in an approximated way, probabilities of Type I error and Type II error of sequential Bayesian procedures for testing one-sided null hypotheses. First, some theoretical results are obtained, and then an algorithm is developed for applying these results. The prior predictive density plays a central role in this study.     

A Probabilistic Perspective on Re-Identifiability

A quasi-identifier is a set of attributes that can be used to re-identify entries in anonymized data sets. A group of individuals is considered about whom quasi-identifying numerical information is disclosed such as date of birth, age, weight, and height. The fraction of individuals is determined whose information is unique in that group and hence is identifiable unambiguously. Nonuniformity can be captured well by a single number, the Kullback-Leibler distance. For example sets of real microdata, given approximations based on Kullback-Leibler distances are accurate. Second, the effect of disclosing more specific or less specific information is analyzed experimentally. Third, the effect of correlation between numerical attributes is measured. A formula gives the re-identifiability level. The approximations are validated using publicly available demographic data sets.     

Diminished tradition of return? Transnational migration in Bolivia's Valle Alto

One‐fifth of the Bolivian population lives abroad, and transnational behaviour strongly links their villages with destination communities. In this article we address whether the increasing difficulty of return migration (owing to legal and geographic barriers) results in diminished social and economic remittances to the country of origin. Results from a questionnaire survey of 417 households in the Valle Alto area of Cochabamba Department in 2007 reveal that monetary remittances account for one‐half of the income of active migrant families (and one‐quarter of income overall), and that transnational cultural ties remain strong. However, after ten years of cumulated time abroad the intention to return to Bolivia drops markedly along with economic and some social remittances. Closer analysis reveals that time abroad reduces these ties through the mediating forces of family members abroad, legal status, and home ownership abroad.
