Le projet de thèse présente différentes méthodes empiriques permettant de détecter des cartels. Il vise à démontrer premièrement que des résultats efficaces peuvent être obtenus avec de simples indicateurs statistiques et deuxièmement que les méthodes économétriques traditionnelles ne sont pas aussi efficaces. / The PhD studies different empirical methods to detect bid-rigging cartels. It shows first that simple statistical screens perform very well to detect bid-rigging infringement. Second, the econometric method of Bajari, well established in the literature, produces poor results.

A prática de 18 procedimentos de rastreamento foi avaliada em profissionais de saúde de um hospital terciário, com idade entre 40 e 69 anos. Dos 364 profissionais elegíveis sorteados, foram entrevistados 333 (91%): 170 auxiliares de enfermagem, 137 médicos e 26 enfermeiras. A realização de procedimentos de rastreamento não recomendados, ou com evidência insuficiente para recomendação, foi relatada por expressiva proporção dos profissionais: eletrocardiograma - 48%, RX de tórax - 57%, dosagem de PSA - 66%, hemograma - 74%. Por outro lado, quase um terço (29%) não havia medido a Pressão Arterial como rastreamento, e apenas quatro (1%) haviam realizado pesquisa de sangue oculto nas fezes. Esses resultados mostram a necessidade de melhor divulgação entre profissionais de saúde das diretrizes sobre rastreamento / The use of 18 screeming procedure was evaluated in health professionals of a terciary hospital, aged 40-69 years. Of the 364 drafted eligible professionals, 333 (91%) had been interviewed: 170 nurses assistant, 137 physician and 26 nurses. The realization of not recommended screening procedure, or with insufficient evidence to recomendation, was related by expressive proportion of the professionals: electrocardiogram - 48%, chest x-ray - 57%, PSA - 66%, hemogram - 74%. On the other hand, almost one third (29%) hadn't measured the blood pressure as screening, and only four (1%) had realized fecal occult blood tests. These results shows the necessity of a better divulgation among health professionals about the screening guidelines
