Desiderata und Perspektiven der Forschung über parasoziale Interaktionen und Beziehungen zu Medienfiguren

Parasocial interactions and relationships are a frequently used framework for studies on media reception in communication research. In spite of its long tradition, however, the concept is still in need of several clarifications. Therefore, this article explores ways to increase the explanatory value of the concept. We briefly present major problems of the definition and conceptualization of parasocial interactions and relationships, namely the understanding of the key elements interaction, relationship, and persona, and suggest first ideas for their solution. Subsequently, opportunities are outlined to enhance the concept by integrating other theories and concepts on media reception and interpersonal perception, taking them from communication research and psychology. Finally, we discuss methodological problems in general and specific shortcomings of the quasi-standard measure, the Parasocial-Interaction-Scale.     

Upper echelons and portfolio strategies of venture capital firms

In this study we analyze how the composition of the top management team (TMT) influences the portfolio strategy choice in venture capital (VC) organizations. We develop a model of risk perception to investigate how education and experience of TMT members impact whether VC organizations invest with a focus on early stage ventures or not, specialize or diversify across industries, and invest with a broad or narrow geographic scope.Evaluation of data on TMTs and portfolio strategies of 136 European VC firms revealed that VC firms with higher proportions of TMT members with science/engineering education and entrepreneurial experience more likely invest with an early stage focus. Furthermore, TMTs with more management education diversify their portfolios more across industries. Finally, the more international experience TMT members of VC organizations have, the broader the geographic scope of investees. We discuss the implications of our findings for the VC literature.     

Trade liberalization and industrial restructuring through mergers and acquisitions

This paper analyzes mergers and acquisitions (M&As) as a channel of industrial restructuring after trade liberalization. Using the Canada-United States Free Trade Agreement (CUSFTA) of 1989 as a source of exogenous variation in trade barriers, I show that trade liberalization increased domestic Canadian M&A activity (Canadian firms buying other Canadian firms) by over 70%. There is no robust link between tariff reductions and either domestic U.S. or cross-border M&As. I also provide evidence that domestic M&As transferred resources from less to more productive firms and that the magnitude of the overall transfer was quantitatively important.     

Stock Externality vs. Symbiosis in a Forest-Air System

Stock externalities and ecological interaction have similar equilibrium effects. The influence on the dynamics of an ecosystem, however, is quite different. The different effects are laid out theoretically in the context of a forest-air model. We compare a centralized, welfare-maximizing policy and decentralized policies. Finally, we numerically simulate the dynamic differences between stock externalities and ecological interaction.     

Determinants of Firm Start-Up Size: An Application of Quantile Regression for Ireland

In this paper we provide empirical evidence on the determinants of firm start-up size using data for the manufacturing sector in Ireland, and compare our results with recent findings for Portuguese manufacturing industries (Mata and Machado, 1996). To allow for firm heterogeneity between firm entrants we use quantile regression techniques for our empirical estimation. We find that the determinants of start-up size differ in their importance for small and large-scale entrants. In particular, industry size and industry growth seem to affect large-scale entrants only.     

Harsh Evaluations of Entrepreneurs Who Fail: The Role of Sexual Orientation,Use of Environmentally Friendly Technologies,and Observers' Perspective Taking

Although there is a pervasive anti‐failure bias in society, we investigate why some entrepreneurs who fail are evaluated more harshly than others. Building on attribution theory and the literatures on prejudice, pro‐social intentions, and perspective taking, we offer an evaluation model of entrepreneurial failure and test this model on 6,784 assessments made by 212 observers. We find that variance in the harshness of failure evaluations depends on both the attributes of the entrepreneur and the attributes of the observer, and the interaction between the two. Specifically, entrepreneurs who are homosexual are evaluated more harshly by some observers and entrepreneurs who use environmentally friendly technology are evaluated less harshly. Moreover, observers high in perspective taking are more ‘lenient’ in their failure evaluations of those who use environmentally friendly technology than those low in perspective taking.     

Multinationals and Training: Some Evidence from Irish Manufacturing Industries

This paper sets out to analyse the effect of plant and sectoral level characteristics on the provision of training to employees using plant level data for Irish manufacturing. There is no clear evidence that foreign owned plants are more likely to provide training. By contrast, we find that they spend less than domestic plants on training, ceteris paribus. There is also no evidence that plants that receive training grants are more likely to provide training. This may be likely to reflect the targeting of training grants on plants that are otherwise unlikely to provide much training. We do, however, find that training activity in the sector, either by other foreign or domestic plants, has a positive effect on plant level training activity, at least for domestic owned plants.     

The rise in student loan defaults

We examine the rise in student loan defaults in the Great Recession by linking administrative student loan data at the individual borrower level to student loan borrowers’ individual tax records. A Blinder-Oaxaca style decomposition shows that shifts in the composition of student loan borrowers and the massive collapse in home prices during the Great Recession can each account for approximately 30% of the rise in student loan defaults. Falling home prices affect student loan defaults by impairing individuals’ labor earnings, especially for low income jobs. By contrast, when comparing the default sensitivities of homeowners and renters, we find no evidence that falling home prices affect student loan defaults through a home equity-based liquidity channel. The Income Based Repayment (IBR) program introduced by the federal government in the wake of the Great Recession reduced both student loan defaults and their sensitivity to home price fluctuations, thus providing student loan borrowers with valuable insurance against negative shocks.     

Testing measurement invariance using multigroup CFA: differences between educational groups in human values measurement

This article applies the testing procedures for measurement invariance using multigroup confirmatory factor analysis (MGCFA). It illustrates these procedures by investigating the factorial structure and invariance of the Portraits Value Questionnaire (PVQ, Schwartz et al.: J. Cross Cult. Psychol. 32(5), 519–542 (2001)) across three education groups in a population sample (N  =  1,677). The PVQ measures 10 basic values that Schwartz postulates to comprehensively describe the human values recognized in all societies (achievement, hedonism, self-direction, benevolence, conformity, security, stimulation, power, tradition and universalism). We also estimate and compare the latent means of the three education groups. The analyses show partial invariance for most of the 10 values and parameters. As expected, the latent means show that less educated respondents attribute more importance to security, tradition, and conformity values.     

Cross-sectional earnings risk and occupational sorting: The role of risk attitudes

This paper investigates to what extent individuals' risk preferences are correlated with the cross-sectional earnings risk of their occupation. We exploit data from the German Socio-Economic Panel, which contains a direct survey question about willingness to take risks that has been shown to be a behaviorally valid measure of risk aversion. As a measure of earnings risk, we use the cross-sectional variation in earnings that is left unexplained by human capital variables in Mincerian wage regressions. Our evidence shows that individuals with low willingness to take risks are more likely to work in occupations with low earnings risk. This pattern is found regardless of the level of occupation categories, region, gender and labor market experience.
