Returns to Foreign Language Skills in a Developing Country: The Case of Turkey

This paper analyses the economic value of foreign languages in Turkey using data on some 6000 adult male wage-earners in 2007. We find positive earnings returns to proficiency in English and Russian, which increase with the level of competence. French and German skills are also positively rewarded, although their return seems mostly linked to the likelihood to hold specific occupations. In contrast, knowing Arabic does not generate an earnings premium. Focusing on English, we check for heterogeneous returns along the conditional earnings distribution. The results are qualitatively invariant when we account for misclassification errors in self-reported English skills.     

The Principle of Conferred Powers and the Division of Powers Between the European Community and the Member States

This article is a reflection about the division of powers between theEuropean Community and the Member States. It focuses on the adventuresand misadventures of the principle of conferred powers in the process ofEuropean integration. Section I is about the initial vertical divisionof powers in the European Community. Section II is dedicated to ananalysis of the progressive erosion of conferred powers during the 70'sand the 80's. Section III refers to the slow return to the applicationof the conferred powers principle that started after the Single EuropeanAct.     

International environmental agreements between developing countries only: learning from the Brazil–Uruguay case over the suspicion of acid rain

This article is about the process of negotiation and implementation of a bilateral environmental agreement between two developing countries. It analyzes the case of the Act of Jaguarão between Brazil and Uruguay on assessing the risk of transboundary air pollution by the President Medici (UTPM) coal-powered thermo-electrical facility in the Candiota region of southern Brazil. The article adds to the scarce literature on international environmental conflict resolution and negotiations between developing countries, especially in Latin America. First, it explains that even with the asymmetry of power between Brazil and Uruguay, negotiation was possible due to a series of factors, such as the interest of Brazilian environmental agencies in improving the monitoring of emissions from UTPM and the international scrutiny of Brazil prior to the upcoming Rio-92 Earth Summit. Both states obtained mutual gains from the agreement by developing ‘joint fact finding’ research and monitoring. Second, different from most of the mainstream literature, the research reveals that weaknesses in institutional agreements, such as a lack of sanctions or deadlines, were not an implementation impediment. In fact, the very weaknesses of the agreement actually enabled authorities in both countries to cooperate in the development of an acid rain monitoring program in the Candiota region, and as a result, to improve air monitoring capacities in both countries. Third, this research shows that the implementation process (1991–2003) produced different results and impacts: it helped to develop technical capacities of environmental agencies in both countries, increased the political power of Brazilian environmental agencies to control UTPM, and pushed for behavioral changes to enable UTPM to respond to the demands of both governments.     

Homicide by a Forensic Female Sample in Brazil: A Preliminary Study

The objective of the study was to evaluate the mental status of all women (n = 14) who were acquitted by reason of insanity of charges of murder or attempted murder and committed to a forensic psychiatric hospital in the state of Rio de Janeiro, Brazil. All cases were retrospectively examined, including medical files, technical records, and forensic experts' official reports. A conclusive psychiatric diagnosis was established using the Structured Clinical Interview for DSM‐IV Axis I and II Disorders and clinical and forensic records. The most common diagnosis was schizophrenia/schizoaffective disorders (n = 8; 57.3%). Most victims (n = 12; 75%) were close relatives of the patients. We found that 43% (n = 6) of the patients had a previous history of violent behavior. According to the initial psychiatric forensic evaluation, 5 patients (35.7%) had psychotic symptoms. It is expected that a growing understanding of motivational factors underlying homicidal behavior in mentally disturbed female offenders may further the implementation of effective preventive and therapeutic interventions.     

Dixit versus Williamson: the ‘fundamental transformation’ reconsidered

Comparing the literature on hold-up and strategic entry deterrence leads to a puzzling role for sunk or specific investments in affecting investor’s incentive. In one case, non-redeployable investments decrease investor’s ex-post bargaining power. In the other they increase it. When the entry deterrence effect is acknowledged, the threat of hold-up against investor is largely weakened. Contrary to previous literature, in this respect, asset specificity may even constitute an endogenous enforcement device for incomplete contracts. We conclude that the impact of asset specificity on investor’s post-contractual power, far from being general, depends on the nature of interactions between contractual arrangements and market structure.     

Taking alleged dictatorship more seriously: Rejoinder to Fried

Fried (in Public Choise, this issue, 2013) claims that Quesada (in Public Choise 130:395–400, 2007) is wrong in showing that the dictator in a dictatorial social welfare function does not necessarily enjoy absolute decision power. This reply revisits, and illustrates by means of an example, the framework where Quesada’s result is obtained. It is argued that Fried’s counterfactual analysis conducted to invalidate Quesada’s conclusion relies on untenable presumptions: (i) that the rules to identify the values of a social welfare function say something about how these values must have been obtained; and (ii) that counterfactual analysis can be conducted in an environment where causes and effects cannot be unequivocally established.
