This paper analyses how market shares for brandname drugs are affected by generic competition. The analysis is based onmicro data for twelve different original drugs, which are all subject togeneric competition. For five of these drugs, we find that the price of theoriginal relative to the average price of the generic substitutessignificantly affects the market share of the original drug. In addition,the introduction of a so called ``reference price' system appears to havehad a significant impact on the market shares of five original drugs. 相似文献

The occurrence and the transmission of large shocks in international equity markets is of essential interest to the study of market integration and financial crises. To this aim, implied market volatility allows to monitor ex ante risk expectations in different markets. We investigate the behavior of implied market volatility indices for the U.S. and Germany under a straightforward mean reversion model that allows for Poisson jumps. Our empirical findings for daily data in the period 1992 to 2002 provide evidence of significant positive jumps, i.e. situations of market stress with positive unexpected changes in ex ante risk assessments. Jump events are mostly country-specific with some evidence of volatility spillover. Analysis of public information around jump dates indicates two basic categories of events. First, crisis events occurring under spillover shocks. Second, information release events which include three subcategories, namely—worries about as well as actual—unexpected releases concerning U.S. monetary policy, macroeconomic data and corporate profits. Additionally, foreign exchange market movements may cause volatility shocks. 相似文献

Governmental public relations, the tax-funded political communication by administrative bodies in Germany, can very well be described as an area of constant conflict. Actors are legally obliged to communicate their policies and decisions to the electorate; on the other hand there is the constant peril of infringements of democratic rights of oppositional actors through communicative measures. Major juridical debates have arisen. Communication studies have approached the subject of legal restrictions of governmental public relations rather cautiously so far. With the issue becoming more and more salient—especially due to the accelerating process of digitisation—the question of whether this is still satisfactory gains importance. This paper is to stimulate a debate. It highlights connections and delimitations between the different perspectives and points out the possible contributions of communication studies to the establishment of valid normative and legal frameworks and the emerging fields of research for the discipline itself. 相似文献

We use time-series of rainfall to estimate the response of body weight to transitory changes in household income in rural Tanzania. We find that the response of body weight to income changes is positive on average, but that the impact is highest for female children, and lower for adults. For female children, a ten-percent increase in household income implies an increase in body weight by about 0.4 kg. In contrast, the body weight of adolescents and young adults is virtually invariant to income changes. 相似文献

Over the past decade, discussion has flourished among practitioners and academics regarding workers’ rights in developing
countries. The lack of enforcement of national labour laws and the limited protection of workers’ rights in developing countries
have led workers’ rights representatives to attempt to establish transnational industrial relations systems to complement
existing national systems. In practice, these attempts have mainly been operationalised in unilateral codes of conduct; recently,
however, negotiated international framework agreements (IFAs) have been proposed as an alternative. Despite their growing
importance, few studies have empirically studied IFAs. This paper starts to fill this gap by studying why corporations adopt
IFAs, based on a qualitative study of the process leading to the signing of a recent IFA. The study’s findings complement
existing research into why corporations adopt IFAs, codes of conduct, and CSR policies by demonstrating that corporate motives
can be linked to a desire to retain a trusting relationship with the labour union movement. In addition, the findings indicate
that the discrete campaign model of stakeholder pressure dominant in previous research should be complemented by a continuous
bargaining model of stakeholder pressure. The paper concludes by discussing differences between these conceptual models of
stakeholder pressure and avenues for future research.

Conflicts between labor unions and nongovernmental organizations (NGOs) often impede private labor regulatory attempts to protect worker rights at supplier factories. Based on a study of a failed private regulatory attempt for Swedish garment retailers, we contribute to existing research into union–NGO relations by demonstrating how conflict arises because unions and NGOs act upon different institutional logics. We also contribute to the institutional logics perspective by challenging the current emphasis on either coexistence or conflict among multiple logics, and showing the heterogeneity in how multiple logics manifest on a local level, how this could shift over time, and suggesting an empirically derived typology of manifestations of multiple logics. 相似文献
