Drivers of internationalization success: a conjoint choice experiment on German SME managers

Internationalization is a common growth strategy for small and medium-sized enterprises (SMEs). However, SMEs face several challenges within the internationalization process. As SMEs are characterized by limited resources, managers are constantly involved in a decision-making process concerning the allocation of the SMEs’ resources. Therefore, internationalization can be understood as a complex, multidimensional decision process. Based on a set of 2244 internationalization decisions made by German SME managers, the present study examines how eight strategic and structural factors drive the perceived international success of SMEs. When applying conjoint choice analysis, the results suggest that especially equity financing in the internationalization process, an appropriate market selection as well as proactive motives, and a long-term scope can drive SMEs’ international success. Moreover, it becomes evident that strategic factors are more relevant for successful internationalization than structural factors.     

Effects of Classroom Composition on the Development of Antisocial Behavior in Lower Secondary School

Early adolescence is a critical period during which classroom composition may affect behavioral development. This study investigated whether classmates’ levels of aggression and delinquency influenced individual antisocial behavior during the first year of secondary school. At this point, students had just transitioned to a new classroom peer environment. A short‐term longitudinal design with four measurement points distributed across the school year was applied. Data were collected from the anonymous self‐reports of 825 seventh graders. Longitudinal negative binomial multilevel analyses revealed that classmates’ antisocial behavior influenced pupils’ behavioral development (other peer influences were controlled). Furthermore, classroom behavioral heterogeneity moderated the peer effect regarding delinquency but not aggression.     

Class origin and young adults’ re-enrollment

This paper examines re-enrollment decisions taken by adults who have previously participated in the labor market in the US. We investigate the influence of social origin on re-enrollment and test hypotheses based on the “status reproduction” argument. We find that young adults from the lower classes re-enroll less often than those from the upper classes and that these differences can be attributed to a large extend to different ability or performance. Beyond the effects of social origin as such, we also scrutinize the effects of the child's class position relative to family status as a more direct implication of the “status reproduction” argument. Our analyses reveal that once young adults from higher status positions have reached their parents’ class, re-enrollment is somewhat less likely to occur. However, this effect of the child's relative class to the parents’ is rather weak.     

Approximate versus Exact Equilibria in Dynamic Economies

This paper develops theoretical foundations for an error analysis of approximate equilibria in dynamic stochastic general equilibrium models with heterogeneous agents and incomplete financial markets. While there are several algorithms that compute prices and allocations for which agents' first‐order conditions are approximately satisfied (“approximate equilibria”), there are few results on how to interpret the errors in these candidate solutions and how to relate the computed allocations and prices to exact equilibrium allocations and prices. We give a simple example to illustrate that approximate equilibria might be very far from exact equilibria. We then interpret approximate equilibria as equilibria for close‐by economies; that is, for economies with close‐by individual endowments and preferences. We present an error analysis for two models that are commonly used in applications, an overlapping generations (OLG) model with stochastic production and an asset pricing model with infinitely lived agents. We provide sufficient conditions that ensure that approximate equilibria are close to exact equilibria of close‐by economies. Numerical examples illustrate the analysis.     

Self-touching and attentional processes: The role of task difficulty,selection stage,and sex differences

Lateral and bilateral self-touching movements were studied in a group of men and women performing a series of attentional tasks. In all tasks, subjects were instructed to selectively attend to, and shadow (i.e., repeat outloud), one of two passages that were presented simultaneously through earphones. Loudness, voice quality, or thematic content determined which passage had to be selected and shadowed. Performance was significantly better when shadowing on the basis of loudness or voice quality (an earlier, easier selection) than when following content (a more difficult selection that occurs at a later stage in the information processing continuum). However, self-touching rates during performance were not simply a function of task difficulty but seemed to depend on the processing stage at which selection occurred as well as on the type of selection involved. Strong, significant associations emerged between lateral self-touching and performance measures in most of the tasks for the women but in only one task for the men. The sample size on which these correlations are based is small and, hence, these findings must be interpreted with caution. However, in the light of previous findings on sex differences with these tasks, the present results suggest that lateral movements may serve different functions in men and women.We are grateful to Dr. Norbert Freedman, Director of the Unit at which this work was carried out, for his encouragement and support during all phases of this project, and to Dr. Marshall Bush for generously making available to us his selective listening tasks. Some findings reported in this paper were included in the second author's master's thesis at New York University, Department of Psychology.
