Team locus of control composition, leadership structure, information acquisition and financial performance: a business simulation study

We argue that team information acquisition mediates the effect of the relationship of team locus-of-control composition and leadership structure on team financial performance in a decision-making context. Hypotheses were tested on 44 teams participating in an elaborate and lengthy international management simulation. As predicted, teams with high average internal locus-of-control scores performed better without leaders and with low locus-of-control heterogeneity. The opposite was found for teams with high average external locus-of-control scores. Contrary to expectations, teams with high locus-of-control heterogeneity did not benefit more from having leaders than teams with low heterogeneity. Information acquisition mediated relationships between locus-of-control composition and performanc

The genesis of top management team diversity: selective turnover among top management teams in Dutch newspaper publishing, 1970-94

We propose that executive team power strengthens a cycle of "homosocial reproduction" that is interrupted only when teams face such compelling needs for diversity as poor organizational performance, high corporate diversification, and tough market competition. Hypothesis tests in data from major Dutch newspaper publishers over 25 years did not support many of our benchmark expectations. Apparently, top management teams tend to close ranks when environmental complexity and pressure increase. Explanations and new research avenues are discussed
