The paper discusses several reliability measures: Scott’s pi, Krippendorff’s alpha, free marginal adjustment (Bennett, Alpert and Goldstein’s \(S\) ), Cohen’s kappa, and Perreault and Leigh’s \(I\) and the assumptions on which they are based. It is suggested that correlation coefficients between, on one hand, the distribution of qualitative codes and, on the other hand, word co-occurrences and the distribution of the categories identified with the help of the dictionary based on substitution complement the other reliability measures. The paper shows that the choice of the reliability measure depends on the format of the text (stylistic versus rhetorical) and the type of reading (comprehension versus interpretation). Namely, Cohen’s kappa and Bennett, Alpert and Goldstein’s \(S\) emerge as reliability measures particularly suited for perspectival reading of rhetorical texts. Outcomes of the content analysis of 57 texts performed by four coders with the help of computer program QDA Miner inform the analysis.  相似文献

We analyze a simple dynamic durable good model. Two incumbent sellers and potential entrants choose their capacities at the start of the game. We solve for equilibrium capacity choices and the (necessarily mixed) pricing strategies. In equilibrium, the buyer splits the order with positive probability to preserve competition, making it possible that a high and low price seller both have sales. Sellers command a rent above the value of unmet demand by the other seller. A buyer benefits from either a commitment not to make future purchases or by hiring an agent to always buy from the lowest priced seller.  相似文献

The formation of R&D alliances has become an increasingly popular way to achieve improved innovation outcomes. However, R&D alliances face high failure rates due to the dual nature, cooperation and competition, of what can be a very challenging inter-firm relationship, a problem that is compounded when an alliance involves more than two partners. As such, it is important to understand the mechanisms that encourage cooperation in multilateral alliances to help firms achieve desired innovation outcomes. In this study, we hypothesize two such mechanisms: equity governance structure and multi-technology scope. We test our hypotheses using panel data from the pharmaceutical industry spanning 15 years. Our results support the idea that equity governance and having a multiple technology scope are positively related to innovation outcomes in multilateral alliances.  相似文献

Environmental regulations play an essential role in managing firm behavior and providing a reference point for the minimum standards of corporate environmental performance, yet certain firms fail to ensure their environmental performance meets these standards. This research focuses on public firms that the US government has penalized for violating environmental regulations and investigates whether these firms subsequently improved their environmental performance. Surprisingly, neither the receipt of a penalty for an environmental violation nor the imposition of a greater penalty was associated with improvements in environmental performance. Instead, a penalty for environmental violation predicted further, albeit mild, deterioration in environmental performance. While the existing literature has established that financial penalties deter most firms from committing environmental violations, this research contributes to this literature by revealing that these penalties fail to motivate firms that have violated environmental regulations to improve their environmental performance.  相似文献

Firm size is commonly used in numerous empirical asset pricing models as a determinant of expected stock returns. Yet there is little consensus over the magnitude and stability of the size premium. In fact, some researchers even question whether firm size should be used as a pricing factor. We collect 1746 estimates of the slope coefficients capturing the association between firm size and stock returns reported in 102 published studies and conduct the first meta‐analysis on the size premium. We find evidence of a strong bias toward publishing statistically significant negative slope coefficients. After correcting for the bias, we find that the literature implies a difference in annual stock returns on the smallest and the largest New York Stock Exchange (NYSE) market capitalization quintiles of 1.72%. For the time periods covered in the sampled articles, we find that the size premium was larger in earlier years and that the intensity of publication bias has been decreasing over time.  相似文献

This paper considers an alternative approachto surface water quality management whensociety is faced with the need to reduce waterpollution in a region with a complicatedregulatory environment. The paper is focusedon a specific kind of negotiation betweenpolluters and an authority, leading toresolution of the problem when there is theinformation asymmetry between the authorityand the polluters, i.e., the true pollutionabatement costs are known to the pollutersonly. This paper reports a laboratory experimentalcase prepared at the Department ofEnvironmental Economics, the University ofEconomics in Prague. The comparison withtheoretical computed first-best results underconditions of full information is included.Political and economic aspects of thesuggested approach are also discussed.  相似文献
