Auction theory, sequential local service privatization, and the effects of geographical scale economies on effective competition

A sequential weakly efficient two-auction game with entry costs, interdependence between objects, two potential bidders and IPV assumption is presented here in order to give some theoretical predictions on the effects of geographical scale economies on local service privatization performance. It is shown that the first object seller takes profit of this interdependence. The interdependence externality rises effective competition for the first object, expressed as the probability of having more than one final bidder. Besides, if there is more than one final bidder in the first auction, seller extracts the entire bidder¿s expected future surplus differential between having won the first auction and having lost. Consequences for second object seller are less clear, reflecting the contradictory nature of the two main effects of object interdependence. On the one hand, first auction winner becomes ¿stronger¿, so that expected payments rise in a competitive environment. On the other hand, first auction loser becomes relatively ¿weaker¿, hence (probably) reducing effective competition for the second object. Additionally, some contributions to static auction theory with entry cost and asymmetric bidders are presented in the appendix

Political economy of municipal water service privatization in Spain: a duration model analysis

This empirical work applies a duration model to the study of factors determining privatization of local water services. I assess how factors determining privatization decision evolve as time goes by. A sample of 133 Spanish municipalities during the six terms of office taken place during the 1980-2002 period is analyzed. A dynamic neighboring effect is hypothesized and successfully tested. In a first stage, private water supply firms may try to expand to regions where there is no service privatized, in order to spread over this region after having being installed thanks to its scale advantages. Other factors influencing privatization decision evolve during the two decades under study, from the priority to fix old infrastructures to the concern about service efficiency. Some complementary results regarding political and budgetary factors are also obtained

Chicago to Iowa City Passenger Rail Service, January 12, 2011

Iowa’s investment in the Chicago to Iowa City passenger rail service will produce more ongoing benefits than costs for Iowa residents and taxpayers over the next 30 years. An Iowa investment of $20.6 million will match a federal investment of $86.8 million for the capital costs of the Iowa segment of the Chicago to Iowa City service. Iowa’s share of the expected gap between revenues and operating and maintenance expense is estimated at $3 million annually. The economic analysis included in this document demonstrates the cost-effectiveness of the Iowa investments in the Chicago to Iowa City service and details the benefits that Iowa can expect from Iowa’s expenditures.

Policy Environment and Public Service Motivation

This article analyzes whether and to what extent the policy environment of civil servants has an impact on their level of Public Service Motivation (PSM). It hypothesizes that public employees working in different policy domains and stages of the policy cycle are diversely motivated by four PSM orientations (Compassion, Commitment to the public interest, Self-sacrifice and Attraction to politics). The empirical results are based on a survey of 6885 Swiss civil servants. They show that those in charge of Welfare State policies are inclined to have higher levels of 'Compassion', whereas those performing core state functions report lower levels. Furthermore, employees whose main tasks are related to policy formulation display high levels of the 'Attraction to politics' dimension of PSM. This study questions the generalization of previous findings on PSM that are based on heterogeneous survey populations.

EZ-IO(®) intraosseous device implementation in a pre-hospital emergency service: A prospective study and review of the literature.

INTRODUCTION: Intraosseous access is increasingly recognised as an effective alternative vascular access to peripheral venous access. We aimed to prospectively study the patients receiving prehospital intraosseous access with the EZ-IO(®), and to compare our results with those of the available literature. METHODS: Every patient who required an intraosseous access with the EZ-IO from January 1st, 2009 to December 31st, 2011 was included. The main data collected were: age, sex, indication for intraosseous access, localisation of insertion, success rate, drugs and fluids administered, and complications. All published studies concerning the EZ-IO device were systematically searched and reviewed for comparison. RESULTS: Fifty-eight patients representing 60 EZ-IO procedures were included. Mean age was 47 years (range 0.5-91), and the success rate was 90%. The main indications were cardiorespiratory arrest (74%), major trauma (12%), and shock (5%). The anterior tibia was the main route. The main drugs administered were adrenaline (epinephrine), atropine and amiodarone. No complications were reported. We identified 30 heterogeneous studies representing 1603 EZ-IO insertions. The patients' characteristics and success rate were similar to our study. Complications were reported in 13 cases (1.3%). CONCLUSION: The EZ-IO provides an effective way to achieve vascular access in the pre-hospital setting. Our results were similar to the cumulative results of all studies involving the use of the EZ-IO, and that can be used for comparison for further studies.

Production et évaluation de l'anticorps NIMP-R14 pour dépléter chroniquement les neutrophiles chez un modèle expérimental d'athérosclérose avancée : la souris ApoE-/- 2 reins-1clip (2K1C)

L'athérosclérose (ATS) est une maladie artérielle inflammatoire chronique à l'origine des nombreuses maladies cardiovasculaires que sont l'infarctus du myocarde, l'accident vasculaire cérébral ou encore l'artériopathie oblitérante des membres inférieurs. L'ATS se définit comme la formation de plaques fibro-lipidiques dans l'intima des artères. Les facteurs de risque majeurs associés à l'ATS sont l'hypertension, l'hypercholestérolémie, le tabagisme, le diabète, la sédentarité, ou encore des prédispositions génétiques. L'ATS peut être asymptomatique durant des années ou alors engendrer des complications aiguës pouvant parfois mettre le pronostic vital en jeu. Les complications les plus graves surviennent principalement lors de la rupture d'une plaque athéromateuse dite vulnérable ou instable. En effet, cette dernière peut se rompre et entraîner la formation d'un thrombus artériel occlusif avec, pour conséquence, l'ischémie/nécrose des tissus en aval. Prévenir le développement de la plaque vulnérable et/ou la « stabiliser » permettrait donc de prévenir les complications cliniques de l'ATS. Cet objectif requiert une connaissance éclairée des mécanismes cellulaires et moléculaires impliqués dans la physiopathologie de l'ATS et de la plaque vulnérable. Les travaux expérimentaux menés au sein du laboratoire du service d'angiologie du CHUV sous la direction du Prof. Lucia Mazzolai ont montré que l'angiotensine II (ang II), produit final de la cascade du système rénine-angiotensine, joue un rôle majeur dans la « vulnérabilité » des plaques athéromateuses (1). Ces travaux ont été réalisés à partir d'un modèle animal original développant des plaques d'ATS vulnérables dépendantes de l'ang II: la souris ApoE-/- 2 reins-1 clip (2K1C). Plus récemment, le laboratoire d'angiologie a mis en évidence une implication directe des leucocytes, plus précisément des macrophages et des lymphocytes T CD4+, dans l'athérogenèse ang II-dépendante (2,3). Dernièrement, des travaux ont également suggéré un rôle possible des granulocytes neutrophiles dans l'ATS (4,5,6,7). Toutefois, les études sont encore limitées de sorte que le rôle exact des neutrophiles dans l'ATS et plus spécialement dans l'ATS induite par l'ang II reste à démontrer. Une des recherches actuelles menée dans le laboratoire est donc d'étudier le rôle des neutrophiles dans le développement de la plaque athéromateuse vulnérable à partir du modèle animal, la souris ApoE-/- 2K1C. Pour évaluer le rôle direct des neutrophiles chez notre modèle animal, nous avons choisi comme méthode la déplétion des neutrophiles circulants par l'utilisation d'un anticorps spécifique. Il a été reporté dans la littérature que l'anticorps monoclonal NIMP-R14 3 permettait de dépléter sélectivement in vivo les neutrophiles dans différents modèles murins (8,9). Cependant, ces études ont utilisé cet anticorps anti-neutrophiles majoritairement sur des périodes expérimentales de durées relativement limitées (12-14 jours) et la question s'est donc posée de savoir si cet anticorps pouvait aussi dépléter les neutrophiles chez notre modèle animal, qui requiert une période expérimentale de 4 semaines pour développer des plaques vulnérables (1). Le but de ce travail a donc été de produire l'anticorps NIMP-R14 et d'évaluer son efficacité chez la souris ApoE-/- 2K1C qui développe des plaque d'ATS vulnérables dépendantes de l'ang II.
