The Portuguese and Dutch merchant empires had a similar geographic distribution with outposts all around the Indian Ocean, which they controlled and manned. Both empires faced the same problem of monitoring their agents in remote corners of the world. Each, however, arrived at a different solution to the monitoring problem. I use a principal–agent model to link different monitoring options to the different organizational structures of the two empires. I further investigate the implications of the model with archival data on labor compensation for Portuguese and Dutch workers overseas.  相似文献

The complex medical environment of today calls for physicians to have an array of leadership skills in addition to a thorough knowledge of their specific practice areas. The American College of Obstetrics and Gynecologists (ACOG) Robert C. Cefalo National Leadership Institute is a 3.5‐day intensive leadership development course targeted to physician leaders. A group of 37 physicians completed the ACOG National Leadership Institute in spring of 2013. At course completion and 6‐month postcourse, participants were asked to complete a retrospective pre‐ and posttest of perceived skill levels in 10 targeted competency areas. Course completion and 6‐month postcourse scores indicated statistically significant improvements in scores on all 10 competency areas, which was supported by a Wilcoxon signed‐rank test of median score difference. Qualitative data gathered at the 6‐month postcourse survey provide examples of how participants had applied their skills. The data presented in the current study suggested that intensive, “short‐burst,” experiential leadership training is an effective approach for leadership skills development in physicians.  相似文献

This study extends theory on the effects of public policies stimulating technology demand and of industry network ties on firm-level entrepreneurial behaviour. We take an institutional perspective to develop a theoretical model examining the mechanisms through which public policies, regulatory uncertainty, and industry network ties affect firm-level entrepreneurial decision-making processes and the ability to introduce highly innovative products and to sustain superior performance. We focus on firm-level effects, which enables the study of the tension between institutional pressures of homogeneity and competitive pressures of heterogeneity for entrepreneurial decision-making processes in environments characterized by policy-induced market demands. To test our hypotheses, we draw on data from a large-scale survey among German renewable energy firms. Our results show that public policies can constrain firm innovativeness and risk-taking behaviour because they steer firms towards a more conservative attitude and discourage the pursuit of high-risk innovation projects. However, firms can counteract these influences and enhance their innovativeness by maintaining close network ties with research associations as we find that innovativeness and a highly innovative product portfolio are key success factors. In summary, these findings provide important implications for the study of public policy effects, industry network ties and entrepreneurial behaviour.  相似文献

This paper argues that the socialist episode in East Germany, which constituted a radical experiment in gender equality in the labor market and other instances, has left persistent tracks on gender norms. We focus on one of the most resilient and pervasive gender gaps in modern societies: mathematics. Using the German division as a natural experiment, we show that the underperformance of girls in math is sharply reduced in the regions of the former GDR, in contrast with those of the former FRG. We show that this East–West difference is due to girls’ attitudes, confidence and competitiveness in math, and not to other confounding factors, such as the difference in economic conditions or teaching styles across the former political border. We also provide illustrative evidence that the gender gap in math is smaller in European countries that used to be part of the Soviet bloc, as opposed to the rest of Europe. The lesson is twofold: (1) a large part of the pervasive gender gap in math is due to social stereotypes; (2) institutions can durably modify these stereotypes.  相似文献

Governments often justify interventions into the financial system in the form of bail outs or liquidity assistance with the systemic importance of large banks for the real economy. In this paper, we analyze whether idiosyncratic shocks to loan growth at large banks have effects on real GDP growth. We employ a measure of idiosyncratic shocks which follows Gabaix (forthcoming). He shows that idiosyncratic shocks to large firms have an impact on US GDP growth. In an application to the banking sector, we find evidence that changes in lending by large banks have a significant short-run impact on GDP growth. Episodes of negative loan growth rates and the Eastern European countries in our sample drive these results.  相似文献

Values and norms as research topics are central theoretical and empirical constructs in communication studies and are also used to substantiate research questions or to interpret results. Despite the relevance of values and norms, a respective debate within the discipline has been neglected so far. It is a challenge to discuss the values and norms of our discipline and to initiate an exchange of the societal relevance of one’s own research. The network “Values and norms as research objects and guiding principles in communication research”, funded by the German Research Foundation (DFG), makes a contribution to this by systematically analyzing values and norms in communication studies and by critically reflecting them. Therefore, the paper proposes to operationalize values and norms as “ought-statements”. Ought-statements either describe a situational state that is explicitly evaluated or address a desirable state. Three elements of an ought-statement are identified, which are coded in a multistage content analysis. The operationalization of norms and values as ought-statements allows not only to examine already known values and norms, but also to assess all possible values and norms, to assess the change of values and norms more validly in long-term studies, and to assess those constructs that are labeled as norms or values by the researchers themselves.  相似文献
