The Impact of Generic Drug Competition on Brand Name Market Shares – Evidence from Micro Data

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.     

Local and spillover shocks in implied market volatility: evidence for the U.S. and Germany

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.     

Rechtlich-normative Rahmenbedingungen der Regierungskommunikation – ein Thema für die Publizistik- und Kommunikationswissenschaft

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.     

How responsive is body weight to transitory income changes? Evidence from rural Tanzania

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.     

TNC Motives for Signing International Framework Agreements: A Continuous Bargaining Model of Stakeholder Pressure

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.

An exploratory investigation of the elements of B2B brand image and its relationship to price premium

Much of the extant work on brand equity in business markets has focused on predicting brand loyalty, as in what brand image elements that make buyers prefer to buy a brand. The question what drives buyers to pay more or less for brands has however been somewhat overlooked, despite price premium being a distinct and economically important outcome of a favourable brand image. In an attempt to answer this question, this paper suggests that the corporate brand image determinants of price premium can be conceptualised into six dimensions: brand familiarity-, product solution-, service-, distribution-, relationship- and company associations. Findings from a small-scale qualitative investigation, based on interviews with buyers of corrugated packaging, are used to illustrate this model as well as to explore its microelements and demonstrate why they can be assumed to be mentally related to buyers' willingness to pay.     

The Evidence on Globalisation

Globalisation is blamed for many socioeconomic shortcomings. I discuss the consequences of globalisation by surveying the empirical globalisation literature. My focus is on the KOF indices of globalisation that have been used in more than 100 studies. Early studies using the KOF index reported correlations between globalisation and several outcome variables. Studies published more recently identify causal effects. The evidence shows that globalisation has spurred economic growth, promoted gender equality and improved human rights. Moreover, globalisation did not erode welfare state activities, did not have any significant effect on labour market interaction and hardly influenced market deregulation. It increased, however, within‐country income inequality. The consequences of globalisation thus turn out to be overall much more favourable than often conjectured in the public discourse.
