European competitiveness: Bargaining between boom and gloom

The newly-renamed European Union is in crisis from economic weakness and political claustrophia. Ralf Boscheck argues that, in addition to a suggested ‘New Founding Contract’, broad-based development of the EU requires that priority is given to adjusting competitive specialization and to centralizing political power. The management of internal and external bargaining is critical. per cent, and 19 per cent respectively. EUROSTAT (1994).     

sCARy! Risk Perceptions in Autonomous Driving: The Influence of Experience on Perceived Benefits and Barriers

The increasing development of autonomous vehicles (AVs) influences the future of transportation. Beyond the potential benefits in terms of safety, efficiency, and comfort, also potential risks of novel driving technologies need to be addressed. In this article, we explore risk perceptions toward connected and autonomous driving in comparison to conventional driving. In order to gain a deeper understanding of individual risk perceptions, we adopted a two‐step empirical procedure. First, focus groups ( $N=17$) were carried out to identify relevant risk factors for autonomous and connected driving. Further, a questionnaire was developed, which was answered by 516 German participants. In the questionnaire, three driving technologies (connected, autonomous, conventional) were evaluated via semantic differential (rating scale to identify connotative meaning of technologies). Second, participants rated perceived risk levels (for data, traffic environment, vehicle, and passenger) and perceived benefits and barriers of connected/autonomous driving. Since previous experience with automated functions of driver assistance systems can have an impact on the evaluation, three experience groups have been formed. The effect of experience on benefits and barrier perceptions was also analyzed. Risk perceptions were significantly smaller for conventional driving compared to connected/autonomous driving. With increasing experience, risk perception decreases for novel driving technologies with one exception: the perceived risk in handling data is not influenced by experience. The findings contribute to an understanding of risk perception in autonomous driving, which helps to foster a successful implementation of AVs on the market and to develop public information strategies.     

New media economics are transforming consumer relations

The introduction of new IT-based technologies is often said to revolutionize media and retail competition, change the power of brands, and make ‘smart shopping’ or ‘e-commerce’ the future of consumer relations. Other sources, however, caution that the underlying ideas are neither new nor likely to significantly change the market environment. It is the purpose of this article to present a brief perspective on:

• 1. 

  1.|Why current changes in media will alter consumer relations;

• 2. 

  2.|Which means of consumer access is likely to dominate;

• 3. 

  3.|How the result affects the case for e-commerce; and

• 4. 

  4.|How this shapes the evaluation of commercial opportunities for established players as well as newcomers.

     

The illusion of independence: Spun-off firms’ risk-taking as a function of status and attachment to the parent firm

This paper examines the post-divestiture behavior of spun-off firms. Drawing on the spin-off literature and middle-status conformity theory, we argue that spun-off firms—as newly independent and publicly traded firms—tend to limit their risk-taking behavior to match the expectations of a crucial audience, i.e., security analysts. Following the logic of middle-status conformity theory, we hypothesize that firms with mid-level status are particularly susceptible to analysts' pressures, whereas high- and low-status firms are free to take greater risks. Crucially, however, we propose that this relationship is less pronounced for spun-off firms that are more attached to their parent firms, as formal and informal linkages between these two types of firms can endure beyond the separation and limit spun-off firms' independence. Using a dataset of 102 spin-off transactions occurring between 1995 and 2010, we find empirical support for a U-shaped relationship between spun-off firms' status and risk-taking. This relationship is attenuated when spun-off firms are more attached to their parents. We contribute to the spin-off literature by demonstrating that a spun-off firm's post-divestiture behavior is determined by the capital market audience's expectations and the attachment to the parent firm. In so doing, we also contribute to the literature on middle-status conformity theory by identifying a boundary condition of the theory. Additionally, we make a methodological contribution by combining ideas from the spin-off and institutional theory literature to develop a particularly comprehensive measure of attachment.     

Competing risks quantile regression at work: in-depth exploration of the role of public child support for the duration of maternity leave

Despite its emergence as a frequently used method for the empirical analysis of multivariate data, quantile regression is yet to become a mainstream tool for the analysis of duration data. We present a pioneering empirical study on the grounds of a competing risks quantile regression model. We use large-scale maternity duration data with multiple competing risks derived from German linked social security records to analyse how public policies are related to the length of economic inactivity of young mothers after giving birth. Our results show that the model delivers detailed insights into the distribution of transitions out of maternity leave. It is found that cumulative incidences implied by the quantile regression model differ from those implied by a proportional hazards model. To foster the use of the model, we make an R-package (cmprskQR) available.     

Efficacy of Cyberbullying Prevention on Somatic Symptoms—Randomized Controlled Trial Applying a Reasoned Action Approach

The theory of reasoned action (ToRA) has been proposed as a framework for cyberbullying prevention design, targeting attitudes and norms. In this study effects of a long (10 weekly sessions) and a short (one day, four sessions) cyberbullying prevention program based on the ToRA were compared with a control group over 9 months. Longitudinal data from 722 students (mean age = 13.36) on cyberbullying, somatic symptoms, attitudes, and norms were analyzed within a structural equation model. Participation in the long intervention group significantly reduced cyberbullying (d = ?0.584) and somatic symptoms (d = ?0.316). No between‐group differences emerged for attitudes and norms. Developmental trajectories and associations were found to be as suggested by ToRA in both cross‐sectional and change‐score analyses.     

Bad luck vs. self-inflicted neediness – An experimental investigation of gift giving in a solidarity game

We experimentally examine the impact of self-inflicted neediness on the solidarity behavior of subjects. In one treatment in our solidarity experiment all subjects face the same probability of becoming needy, in the other treatment subjects have the choice between a secure payment and a lottery which includes a certain probability of becoming needy. Then all subjects are asked how much they will give to losers in their group to investigate if people are willing to give the same gifts whether or not subjects are responsible for inequality in payoffs. We found evidence for allocative as well as for procedural utility concerns.     

Combining Experts' Risk Judgments on Technology Performance of Phytoremediation: Self-Confidence Ratings, Averaging Procedures, and Formative Consensus Building

Expert panels and averaging procedures are common means for coping with the uncertainty of effects of technology application in complex environments. We investigate the connection between confidence and the validity of expert judgment. Moreover, a formative consensus building procedure (FCB) is introduced that generates probability statements on the performance of technologies, and we compare different algorithms for the statistical aggregation of individual judgments. The case study refers to an expert panel of 10 environmental scientists assessing the performance of a soil cleanup technology that uses the capability of certain plants to accumulate heavy metals from the soil in the plant body (phytoremediation). The panel members first provided individual statements on the effectiveness of a phytoremediation. Such statements can support policymakers, answering the questions concerning the expected performance of the new technology in contaminated areas. The present study reviews (1) the steps of the FCB, (2) the constraints of technology application (contaminants, soil structure, etc.), (3) the measurement of expert knowledge, (4) the statistical averaging and the discursive agreement procedures, and (5) the boundaries of application for the FCB method. The quantitative statement oriented part of FCB generates terms such as: "The probability that the concentration of soil contamination will be reduced by at least 50% is 0.8." The data suggest that taking the median of the individual expert estimates provides the most accurate aggregated estimate. The discursive agreement procedure of FCB appears suitable for deriving politically relevant singular statements rather than for obtaining comprehensive information about uncertainties as represented by probability distributions.
