Purpose: The present study investigates how the performance of Greek bank branching varies when the external environment causes dramatic changes that are reflected in recession and capital control effects.

Design/Methodology: A unique dataset of accounting Profit and Loss statements of retail branches of a systemic Greek commercial bank, closely supervised by the European Central Bank (ECB), is utilized. A profit bootstrap Data Envelopment Analysis (DEA) model is selected to measure the bank branch efficiency. The derived efficiency estimates are analyzed through a second-stage panel data regression analysis against a set of efficiency drivers related to branch profitability, diversification of income, branch size, and branch activity.

Findings: The results indicate that recession negatively affects branch efficiency in the short and long run. The occurrence of recession significantly intensifies the efficiency premium of branch profitability, reduces the efficiency premium of diversification of income (i.e., a negative efficiency effect is recorded during the early recession period), while mitigating the generally negative efficiency effect of branch size. The analysis of efficiency effects from the deep recession period that encompasses capital controls reveals the importance of diversification of income for the improvement of profit efficiency at bank branch level.

Originality/Value: This is the first branch banking study that explores branch efficiency alteration and the dynamic of branch efficiency drivers when the economy suddenly enters recession and afterwards when conditions are becoming extremely difficult and consequently capital controls are imposed on the economy.

We review previous research on intergenerational conflict, focusing on the practical implications of this research for organizational leaders. We explain how the interaction between the interpersonal and intertemporal dimensions of intergenerational decisions creates the unique psychology of intergenerational decision-making behavior. In addition, we review the boundary conditions that have characterized much of the previous research in this area, and we examine the potential effects of loosening these constraints. Our proposals for future research include examination of the effect of intra-generational decision making on intergenerational beneficence, consideration of the role of third parties and linkage issues, investigation of the effects of intergenerational communications and negotiation when generations can interact, examination of the role of social power in influencing intergenerational interactions, investigation of the interaction between temporal construal and immortality striving, and exploration of the ways in which present decision makers detect and define the intergenerational dilemmas in their social environments.

Federal “No Child Left Behind” legislation, which enables students of low-performing schools to exercise public school choice, exemplifies a widespread belief that competing for students will spur public schools to higher achievement. We investigate how the introduction of school choice in North Carolina, via a dramatic increase in the number of charter schools, affects student performance on statewide end-of-year testing at traditional public schools. We find test score gains from competition that are robust to a variety of specifications. Charter school competition causes an approximately one percent increase in the score, which constitutes about one quarter of the average yearly growth.

Demographic faultlines (i.e., potential subgroup splits based on demographic attributes) have been argued to have effects over and above those of diversity. Yet, faultlines, much like diversity, do not seem to have positive or negative effects on performance per se, but to be affected by contextual variables as well as intermediate outcomes, such as relationship conflict. Relationship conflicts, a major threat to teamwork, are particularly likely to arise between subgroups. Thus, with the objective to shed some light on why and how exactly faultlines impact group outcome, we investigate the effect of faultline strength and distance on performance through relationship conflict as well as the effect of faultline strength on performance via relationship conflict, contingent on the level of faultline distance. To test our hypotheses we used data gathered in a laboratory setting with 267 graduate students. Results provide strong support for the extension of the faultline model.

Purpose: This chapter aims: (a) to extend biased net models of homophily to complete networks; (b) to extend the scope of application of these models to processes of social exchange in a small-group laboratory setting; and (c) to link the theoretical model of attraction and repulsion with a standard statistical model of logistic regression as a way of estimating and evaluating the model.

Methods: We discuss the logic of biased net theory and show how it leads to formal mathematical models of tie formation and tie renewal under mechanisms of attraction and repulsion. We then estimate key theoretical parameters in the models by means of logistic regression.

Findings: The estimated effects of homophily in our models are moderate in strength, weaker than corresponding reciprocity effect, and processes of tie formation and tie renewal are driven more by considerations of direct reciprocity than group membership. Under attraction, homophily effects are stronger for tie renewal than tie formation. Under repulsion, the opposite holds.

Limitations: Participants in our study are divided into two groups based on a criterion that is likely to have been too weak to induce strong group identity. Measures that enhance the sense of group identity need to be introduced in future studies.

The role of gender in psychiatric disorders is not well understood, but several broad trends are known: while men and women experience psychiatric symptoms at roughly the same rate, women are more likely to experience depressive symptoms (Kessler et al., 1993) and men are more likely to experience substance use disorders (DHHS, 1999). However, women are more likely to use primary care services for mental health care than are men (Wells et al., 1986). Equally controversial and not well understood has been the differential responses to treatment interventions by gender (Kornstein, 1997). One recent study found that a depression intervention was more cost-effective for women than for men (Pyne et al., in press). Indeed, the study found that the intervention was essentially cost and outcome neutral for men, while women were found to have a cost-effectiveness ratio of over $5000 for each QALY saved.

Although social influence plays an important role in organizational groups, past findings regarding culture's impact on social influence have been scarce and inconsistent. Past research has found that people from collectivist cultures are more susceptible to social influence, while other studies have found the opposite or no effect. One major weakness of prior research on social influence is the predominantly cognitive orientation that has underemphasized the role of affect in culture's impact on social influence. We address this weakness by outlining an affective model of social influence, thereby expanding our understanding of social influence in multicultural decision-making groups.

This chapter derives from the movieDr. Strangelovecues for exploring questions about the quest for methodological insularity and purity in socio-legal research. Steven Lukes’ classic three-dimensional model of power provides an intellectual focus for the core exploration of relations between epistemology and data generation, the two key elements that we usually identify with methodology. The discussion culminates in an affirmative argument for the value of approaching methodology as jazz, the creative popular music that grounds reliable, humane sense in Kubrick's movie and provides an apt analogy for much of the leading scholarship in the LSA tradition.
