Collusion under Yardstick Competition: An Experimental Study
The effectiveness of relative performance evaluation schemes, such as yardstick competition, can be undermined by collusion.The degree to which the regulated agents manage to collude will be affected by the particulars of the scheme.We hypothesize that in a repeated game setting schemes will be more prone to collusion the smaller are the rents to the agents in case they behave non-cooperatively.We illustrate the relevance of this hypothesis by means of an economic experiment in which we compare the efficiency of two performance evaluation schemes.performance evaluation;competition;efficiency;games;collusion;yardstick

“I Wish I Had AIDS”: A qualitative study on access to health care services for HIV/AIDS and diabetic patients in Cambodia
Financially stricken Cambodian patients with diabetes and HIV/AIDS typically encounter multiple, serious barriers to effective care. This process may extend over many years and involve numerous rounds of diagnosis and treatment as the disease progresses from initial symptoms to longer term complications. Living with both the impact of the disease and this ongoing struggle for care can severely disrupt the everyday life of both sufferers and their families. Our retrospective study adopted qualitative research methods to collect data from HIV/AIDS and diabetic patients enrolled and not enrolled in treatment programs at varying institutions in urban and rural settings. Using purposive sampling techniques, a total of 25 HIV/AIDS and 45 diabetic patients were recruited. Semi-structured and open-ended interviews were used to collect information on patient experiences of different phases in the on-going process of seeking care and treatment. The findings indicate that both HIV/AIDS and diabetic patients encounter multiple supply- and demand-side barriers to care at different stages of their illness. More strikingly, our research findings suggest that supply-side barriers, for example rationing systems or targeting strategies that limit access to free treatment or social assistance, are substantially higher for diabetic patients. This perceived inequity had a profound impact on diabetic patients to the extent that some “wished they had HIV/AIDS”. These findings suggest that there is an urgent need to widen the focus of health care to address the substantial and increasing burden of disease resulting from diabetes and other serious chronic disorders in Cambodia and many other low/middle income countries.
Het 'bijzondere' van de Schelde: de abiotiek van het Schelde-estuarium
The Scheldt estuary is a vast ecosystem in which powerful natural forces prevail. Tidal action is a key element in the functioning of the estuary. The combination of tide and discharge results in a salinity gradient that is characterized by strong variations in the brackish part. The estuary is a highly turbidsystem. The load of suspended solids is determined by acomplex mix of factors. The dynamic interactions of the physicochemical and morphological parameters lead to a range of various habitats, with highly fluctuating conditions. This, together with the very heavy human impact, both morphological and chemical makes the estuary a very stressed environment in which the survival of plants and animals requires special adaptations
