This study analyses the geographic integration of electricity wholesale markets with a focus on Germany and its neighbouring countries. We employ various indicators based on publically available data and find that electricity markets have become more integrated since the sector inquiry undertaken by the European Commission in the years preceeding 2006. However, European markets are not yet fully integrated. The results also suggest that stronger (and costly) integration towards certain countries may have only little or adverse effects on electricity wholesale prices in Germany. Finally, in the past, German electricity wholesale prices have appeared too low so as to trigger investments into new generation capacity. To that end prices do not appear inflated.

The purpose of this paper is to propose a framework for the monitoring of new technology introduction in a B2B environment. We focus on B2B environments, i.e. on projects where a new technological solution is implemented (and often jointly developed) with a client being either a company or an organization. In such a situation, where a supplier and its client agree to implement a new technology, both are exposed to a risk. The management of these risks can be handled through a couple of approaches: control or trust. The management literature has put a lot of attention on these two modes that play an important role because they drive the quality of the relationship between partners. We will explore their respective roles and build a methodology to monitor them along the life of a buyer-supplier relationship aiming at implementing new technology.

We propose that ambiguity aversion, as introduced in the literature on decision making under uncertainty, drives a preference for established brands in multiattribute choices among branded alternatives. Established brands are those for which belief in quality is held with greater confidence, even if specific attributes might be inferior to those of competing, less-established brands. In five experiments, we examine the role of ambiguity aversion in the preference for dominated, established brands. We first show a correlation between ambiguity aversion (revealed through choices among monetary lotteries) and the preference for established brands. We then show that the preference for established brands is enhanced when ambiguity aversion is made more salient in unrelated preceding lottery choices. Thus, ambiguity aversion carries across choices. In addition, ambiguity aversion and the preference for established brands are both enhanced when subjects anticipate that others will evaluate their lottery choices. Finally, ambiguous information about brand attributes tends to increase the preference for established brands.

Although previous research has demonstrated the importance of emotions in ultimatum bargaining, this research provides a more direct, convergent test of the role of anger in explaining rejections of unfair offers in ultimatum bargaining. First, using appraisal theory of emotions, this research examines the extent to which the cognitive appraisal of unfairness leads to the emotion of anger, which in turn, drives punitive behavior (i.e., rejection of offers). Second, this research explores the possibility of decoupling the emotion of anger from its antecedent appraisal of unfairness in order to attenuate responders' inclination to reject unfair offers. Third, following the current research tradition that goes beyond a valence-based approach, we differentiate between the negative emotions of anger and sadness and examine whether it is the specific emotion of anger that is relevant to the cognitive appraisal of unfairness or the general negative valence of the emotion.

This paper is concerned with the tension between consumer persuasion and freedom of choice. We study how assertive language (as in the slogan Just do it!) affects consumer compliance in hedonic vs. utilitarian contexts. Previous literature consistently claimed that forceful language would cause reactance and decreased compliance. However, we find in four studies that assertive persuasion is effective in contexts involving hedonic goods and hedonically framed utilitarian goods. Our hypotheses emerge from sociolinguistic research and confirm the relevance of linguistic research in consumer behavior.
