This paper considers enhancements of a comparatively new method to detect cartels, the System of Cartel Markers (SCM), introduced by Blanckenburg and Geist (Int Adv Econ Res 15(4):421–436, 2009). The aim of SCM is to find illegal collusion on legal markets with observable market data. It uses expected behavior patterns such as low level of capacity utilization, slackness of price adjustments to exogenous shocks, excess rates of return, nearly constant capacities, less price changes and lower variance of capacity growth rate. However, the testing of cost efficiency is lacking so far. Following Leibenstein’s (Am Econ Rev 56:392–415, 1966) X-inefficiency theory, we assume that cartel members face lower competition and hence, tend to be less cost efficient. Therefore, we enhance SCM and use cost efficiency as a further marker in order to detect cartels. We apply SCM to the German cement cartel and find empirical support for some markers. The proposed methodology may be used for antitrust screening and regulatory purposes.  相似文献

Autosomal STR typing alone seems to be no sufficient tool for resolving deficiency cases (e.g. cases of questioned paternity or half-sibships). Therefore, we investigated whether the additional analysis of RFLP single locus probes can improve the solution of such complicated kinship cases. We analyzed 207 children and men from 101 families using the AmpFlSTRIdentifiler multiplex PCR kit and three RFLP single locus probes. A comparison between each child and all unrelated men resulted in 11,023 man / child pairs. Less than three excluding STRs were found in 125 child / unrelated man pairs (1.13%). Additional analysis of RFLP results reduced the number of ambiguous cases to 35. Half-sibling pairs were simulated using STR results from 20 cases with high paternity probabilities (group 1) and relatively low paternity probabilities (group 2). Using a commercially available computer program we calculated probabilities for 778 half-sibling pairs. In 35 pairs (4.49%) half-sibling probabilities over 90.0% could be calculated. Additional investigation of RFLP single locus probes did not lead to a more reliable evaluation of these results. The combined investigation of autosomal STRs and RFLP single locus probes can satisfactorily solve deficient paternities but does not contribute to the solution of questioned half-sibships.  相似文献

Can, and will, lawyers police their clients? This article aims to shed light on the private front-line workers of the Financial Action Task Force on money laundering (FATF). The analysis is based on a study of how Swedish lawyers perceive and handle obligations to police clients within FATF style risk-based anti-money laundering/counter terrorism (AML/CTF) regulation. We find that the lawyers were reluctant to taking on the responsibility for AML/CTF, and that their front-line work was directed towards being compliant enough. Relatedly, we identify several practices of separation that serve to mediate between the conflicting aims and interests in the everyday of this form of private policing. Another finding is that the lawyers by and large position themselves as knowledgeable actors, and view risks of AML/CTF as knowable. Nevertheless, lawyers experienced a principle clash between being ‘not banks’, and being front-line workers for FATF. In particular, the lawyers perceived their role as front-line workers to be more complex due to their professional norms and ethics on client privilege, and what they saw as the proper role of lawyers, being in conflict with the obligation to report clients and their transactions. In concluding, we suggest that paying more attention to the everyday experience of front-line workers when devising regulatory tools may be a way to promote engagement in ‘true’ crime prevention on their part.  相似文献

Cross-sectional studies of bullying mask variability in categories of and persistence of bullying victimization. Longitudinal, individual-level data offers a greater insight into schoolchildren’s psychosomatic maladjustment as a consequence of bullying. Swedish schoolchildren (n = 3,349), with unique identifiers, in 44 schools (4th–9th grade), answered a questionnaire at baseline and 1-year follow-up. Longitudinal trends for nonvictims (88%), ceased victims (4.7%), new victims (5.7%), and continuing victims (1.6%) revealed that new victims had the largest decrease in well-being; continuing victims had a smaller though not significant decrease; while ceased victims showed a small, (nonsignificant) increase in well-being over the measurement period. It was also discovered that children not bullied at baseline but bullied subsequently, differed, at baseline, from their never-bullied peers through lower levels of overall well-being. It is argued that this finding has implications for prevention strategies.  相似文献

Abstract

Sexual harassment at institutions of higher learning is not a new phenomenon but discussions of this problem in the sporting arena are still scarce. Many studies have focused on student-teacher relationships, few investigations have researched athlete-coach relationships, and hardly any have conducted comparative analyses. This study compares the perceptions and the experiences of sexual harassment of athletes and students. It is not a surprise that most harassing behaviors are extended from men towards women. Thus, this investigation analyses and compares female student/male teacher interactions with female athlete/male coach relations. The findings indicate that sexual harassment is slightly more prevalent in academia than in athletics. However, in order to guarantee a safe learning environment for all participants in both domains, it is necessary to formulate clear guidelines, to set up educational workshops and to implement intervention programs.  相似文献

Between 1958 and 1960, the French domestic security and intelligence services came to establish a close, multi-layered, and secret working relationship with their German counterparts. The purpose of this collaborative arrangement was to enlist German support in combating the subversive activities of the Algerian Front de Libération Nationale, whose members had taken refuge in Germany. In particular, the metropolitan authorities sought to impose on their German counterparts some of the same methods of colonial policing and intelligence that characterized their own counter-insurgency in France. These efforts proved counter-productive, however, for in internationalizing the Algerian war, they drew public attention to the colonial nature of France's hold over Algeria.  相似文献

This paper examines the association between stored drinking water quality and sanitation on diarrhoea incidence among under-five children in Ethiopia. Using primary household survey data and microbiological water quality testing for Escherichia coli, our results show that uncontaminated stored drinking water and safe child stool disposal are associated with decreased child diarrhoea incidences of 18 and 20 percentage points, respectively. In contrast, neighbourhood concentration of pit latrine shows an increased incidence of child diarrhoea of 16 percentage points. To protect rural children from the risk of contracting diarrhoea, improving household drinking water quality and changing people’s behaviour towards safe sanitation practices is needed.  相似文献
