The opinion dynamics model introduced by Deffuant and Weisbuch as well as the one by Hegselmann and Krause are rather similar. In both models individuals are assumed to have opinions about an issue, they meet and discuss, and they may adapt their opinions towards the other agents` opinions or may ignore each other if their positions are too different. Both models differ with respect to the number of peers they meet at once. Furthermore the model by Deffuant and Weisbuch has a convergence parameter that controls how fast agents adapt their opinions. By defining the reversed parameter as self-support we can extend the applicability of this parameter to scenarios with more than one interaction partner. We investigate the effects of changing the number of peers met at once, which is done for different population sizes, and the effects of changing the self-support. For describing the dynamics we look at different statistics, i.e. number of cluster, number of major clusters, and Gini coefficient.
This article offers a new perspective for research on opinion dynamics. It demonstrates the importance of the distinction of opinion and attitude, which originally has been discussed in literature on consumer behaviour. As opinions are verbalised attitudes not only biases in interpretation and adoption processes have to be considered but also verbalisation biases should be addressed. Such biases can be caused by language deficits or social norms. The model presented in this article captures the basic features of common opinion dynamic models and additionally biases in the verbalisation process. Further, the article gives a first analysis of this model and shows that precision as bias in the verbalisation process can influence the dynamics significantly. Presenting and applying the concept of area of influential attitudes the impact of each parameter (selective attitude, selective interpretation, and precision) is analysed independently. Some preliminary results for combined effects are presented.
Do potential entrepreneurs exploit welfare-destroying opportunities as much as they exploit welfare-enhancing opportunities as it is assumed in several normative models? Do we need to prevent potential entrepreneurs from being destructive or are there intrinsic limits to harm others? We experimentally investigate how people with different entrepreneurial intent exploit risky investment opportunities that are associated with negative and positive externalities. We find that participants who consider entrepreneurship as a future occupation invest significantly less than others in destructive opportunities. Nevertheless, our results support prior evidence that the entrepreneurially talented invest more in destructive opportunities. The latter effect seems to be entrepreneurship-specific, because the investment behavior of the generally more talented does not differ from that of other participants. Taken together, our results suggest that people who are willing to exploit destructive opportunities do not only do this in private ventures, but also – and maybe even more so – in wage employment.
The authors develop a model of investor reactions to new product development (NPD) failures in high technology firms. They propose that a firm’s financial and managerial capabilities, and its strategic focus on R&D, influence investors’ perceptions of the firm’s market value after NPD failure and that these effects are contingent on the development stage of the failed product. Using data on 148 NPD failures of publicly traded biopharmaceutical firms and an event study methodology the authors find support for their hypotheses. They show that the relationships between a firm’s (a) financial capabilities, (b) managerial capabilities, and (c) strategic focus on R&D, respectively, and the decline of firm market value after NPD failure are more negative for products that fail in late development stages than for products that fail in early development stages. The authors’ results highlight the importance of a conjoint consideration of product-level and organizational-level effects in explaining investor reactions to NPD outcomes.
We document the predictive relevance of the behavioral inhibition system (BIS) and the behavioral approach system (BAS) in a novel domain of societal importance: entrepreneurship. Based on structural equation models, Study 1 (N = 320) reveals that BAS reward responsiveness (BAS-RR) has a negative and BAS fun seeking (BAS-FS) has a positive association with entrepreneurial intent. Similar results emerge for Study 2 (N = 470): BAS-RR is negatively and BAS drive (BAS-D) is positively related to entrepreneurial intent. Additionally, Study 2 includes entrepreneurial experience, which is negatively related with BAS-RR and positively with BAS-D. We do not find any significant relationship between the BIS and entrepreneurial intent or experience. Our results support the multidimensionality of the BAS, with the subscales being differently associated with both entrepreneurial intent and experience. Finally, by simultaneously including intent and experience, Study 2 makes a methodological contribution related to the validity of student samples when analyzing entrepreneurial intent.
For a sample of 1243 European companies, we analyse the link between firm type and foreign direct investment (FDI) locations. We find substantial empirical evidence that being a family firm does not only affect the overall propensity for FDI, but that this effect is also specific to target regions. Overall, family firms invest more than managerial-led firms, particularly in Europe and North America. Furthermore, the BRIC countries, Brazil, Russia, India and China do not constitute a homogeneous attractiveness cluster for FDI.
Although research on public service motivation (PSM) is vast, there is little evidence regarding the effects of PSM on observable behavior. This article contributes to the understanding of the behavioral implications of PSM by investigating whether PSM is associated with prosocial behavior. Moreover, it addresses whether and how the behavior of other group members influences this relationship. The article uses the experimental setting of the public goods game, run with a sample of 263 students, in combination with survey‐based PSM measures. A positive link is found between PSM and prosocial behavior. This relationship is moderated by the behavior of other group members: high‐PSM people act even more prosocially when the other members of the group show prosocial behavior as well, but they do not do so if the behavior of other group members is not prosocial.
Hybrid entrepreneurs are entrepreneurs who are simultaneously working as paid employees. Although they constitute a systematic and large part of new firm creation, their possibly distinct responsiveness to public policy is not yet studied. Arguing for the need to consider hybrid entrepreneurs in public policy, we analyze the introduction of one-stop shops for faster and simplified firm registration in Mexico. We find that hybrid entrepreneurs are more responsive to changes in entry regulation than full-time entrepreneurs. While both the best and least educated people respond to the reform, the effect is most pronounced for highly educated hybrid entrepreneurs.
Come on and Take a Free Ride: Contributing to Public Goods in Native and Foreign Language Settings
(2016)
Business schools around the world must prepare their students for two realities: operating in an English-speaking business world and working in teams. As yet, there is limited understanding of how operating in a native or a foreign language impacts students’ propensity to free ride in group settings. Building on general dual process theory of higher cognition and using a unique dataset of 276 Dutch business school students, we find that students are more inclined to free ride in a foreign language setting than in a native language setting. A student’s conscientiousness attenuates this relationship such that this effect is stronger for students who are less conscientious, and weaker and almost absent for those who are more conscientious. After a student decides not to free ride but to positively contribute to the group, the specific level of contribution is not affected by foreign language. We discuss implications for practice, policy, theory, and future research.
This study examines the relationship between prenatal testosterone exposure (PTE) and selection into entrepreneurship. We argue that the relationship between PTE and entrepreneurial intent is positive and mediated by general and domain–specific risk–taking related to financial investment and professional career. Using the second–to–fourth digit ratio (2D:4D) as noninvasive retrospective marker for PTE, we identify two–step mediation effects of PTE on entrepreneurial intent through both general and domain–specific risk–taking. To account for possible socialization–based effects, we control for gender and parental self–employment. Applying ordinary least squares (OLS) regression analyses and structural equation models, we provide empirical evidence for a biological association between 2D:4D and entrepreneurial intent.
