We examine how open procurement data affect the competitiveness of award procedures and the execution of government contracts. The European Union recently made its historical procurement notices available for bulk download in a cohesive and user-friendly database. Comparing government contracts above and below EU procurement size thresholds, we find that, after the open data initiative, procurement officials are more likely to award treated contracts through open bidding. In cross-sectional analyses, we document variation in the open bidding effect consistent with two underlying mechanisms: (1) increased scrutiny by NGOs and investigative journalists and (2) learning by national procurement regulators. However, treated contracts are also more likely to experience costly modifications because the shift to open bidding introduces rigidity that limits officials’ discretion in selecting suppliers based on private information. Overall, our evidence indicates that open procurement data promote competitive bidding but lead to contracts with weaker execution performance. These inferences also hold in an alternative open data setting.  相似文献

Regression analyses based on a sample of 3372 nonunionized and unionized employees showed that, while the desire to join a union is associated with a wide range of work attitudes, perceived company performance, and facets of satisfaction, one's desire to leave one's union is associated with a narrow range of economic concerns. Implications of the findings are discussed in light of the declining unionization rate in the United States.  相似文献

We use a variety of techniques to examine the nature and degree of co‐movement among Australian state business cycles. Consistent with the results of Dixon and Shepherd (2001 ), we find that these cycles move quite closely together, with particularly strong links between the cycles of the larger states. We then seek to understand the causes of this co‐movement by using an unobserved components model to distinguish between various shocks and their transmission. Our model implies that the major source of this co‐movement in state activity is the commonality of shocks affecting state cycles. In contrast, spillovers of region‐specific shocks appear to play only a minor role in creating co‐movement, though region‐specific shocks themselves have a moderate influence on cyclical fluctuations. These findings are consistent with the results of recent studies for the United States, Canada and Europe, where common shocks have also been found to dominate regional cyclical activity.  相似文献

This article analyzes the complex history of the important new product liability directive of the European Community. The member countries must amend their laws and meet the directive's proconsumer standards and spirit. The lengthy political evolution of this policy involved many aggressive constituencies, including nations, parts of the European Community governance structure, business federations, consumer organizations, and other functional interest groups.  相似文献

The objective of this study is to investigate the internal risks and benefits from smoking over the lifetime of a male individual. It differs from many earlier studies in that it focuses on the costs borne by the individual, as opposed to external or societal costs. It also includes the benefits from smoking which play an important role in the individual's smoking decision. Risk-benefit ratios range from 0.25 to 3.67 depending on the tar and nicotine content of cigarettes, the discount or time preference rate, the value of a life year, and the price elasticity of demand for cigarettes.  相似文献

Audience segmentation and focus group methods were used to evaluate consumer reactions to a risk/benefit/option message about agricultural chemicals in the food supply. The approach was well-received and showed potential for raising consumers' concerns regarding health and environmental risks associated with pesticides, along with confidence in their ability to minimize exposure to residues. Concern and confidence increased most among consumers who already were concerned and who were most removed from agriculture.  相似文献

An urban community in New Zealand was the site of a field experiment designed to assess different approaches to increasing household participation in a cnrbside recycling program. Two different commitment interventions were delivered using a 2 × 2 factorial design, and weekly participation data were collected over 12 weeks. Half of the households were asked to make an explicit verbal commitment to participate in the program, while half were not. Half of the households were also requested to pay for their recycling bins, while half received bins free of charge. All households received the same educational and promotional information, specifically designed to maximize participation, regarding program details. The verbal commitment intervention significantly increased participation relative to the no commitment intervention, while difficulties in the operationalization of the financial commitment intervention made it difficult to assess its validity as a construct. Notably, differences in participation rates between the control group, who received only educational and promotional materials, and the experimental treatment groups were not statistically significant. The discussion focuses oh the increasing importance of well-designed educational materials for encouraging voluntary curb-side recycling.  相似文献

Abstract. We examine six accounting-based stock price anomalies using two sets of tests to determine the extent to which the anomalies (1) represent market mispricing or (2) reflect premia for unidentified risks. Market mispricing is indicated if the anomalous returns are concentrated around subsequent earnings announcements in patterns suggesting that the earnings information causes traders to re-examine their prior (incorrect) beliefs. Mispricing is also indicated if anomalous returns on zero-investment portfolios are positive, period after period. Our results indicate that an anomaly based on earnings momentum probably reflects market mispricing, but that two value-glamour anomalies (based on the book-market ratio and the earnings-price ratio), and two anomalies based on computerized fundamental analyses (from Ou and Penman 1989 and Holthausen and Larcker 1992) are more likely to reflect risk premia than indicated by prior research. Evidence on a sixth anomaly, based on price momentum, is mixed.  相似文献

Recently, from 21–25 October 2004, I participated in the Norway Social Forum (NSF). It was the most successful regional social forum that I have attended. The forum expressed what I call an autonomist electoral politics. Such a politics combines short‐term electoral tactics with long‐term social movement autonomy. Autonomist electoral politics outlines the direction that forthcoming local, regional and national forums should take. I use the example of the NSF to respond to Peter Marcuse’s article on social forums and social movements. Le Forum social norvégien (FSN) s’est tenu du 21 au 25 octobre 2004, et ce fut le forum social régional le plus réussi auquel j’ai participé. Il a exprimé ce que j’appelle une politique électorale autonomiste. Une telle politique allie des tactiques électorales à court terme et une autonomie des mouvements sociaux à long terme. Elle définit l’orientation que devrait prendre les forums locaux, régionaux et nationaux à venir. J’utilise ici l’exemple du Forum social norvégien pour répondre à l’article de Peter Marcuse sur les forums et mouvements sociaux.  相似文献
