Why do organisms cooperate with each other? This seemingly simple question has motivated a staggering amount of theoretical and experimental research. When cooperating with others carries a direct fitness cost for the individual, natural selection should act against such behavior.

How Do Organizational Capabilities Shape Industry Dynamics?

This paper aims to reconcile the logic behind stochastic models of firm growth and the notion of organizational capabilities as drivers of economic performance. In the proposed behavioral model of bounded rational firms, two mechanisms drive growth: independent stochastic growth of individual opportunities and the process by which firms capture new opportunities.

Agrarian Structure and Endogenous Financial System Development

The development of the financial system is shown, both historically and in contemporary data, to be adversely affected by inequality in the distribution of land. To accommodate these empirical findings, a theory is developed that highlights the incentives of landowners to oppose competition in the financial sector. The theory provides an explanation for the co-incident development of the financ...

How Early Hormones Shape Gender Development.

Many important psychological characteristics show sex differences, and are influenced by sex hormones at different developmental periods. We focus on the role of sex hormones in early development, particularly the differential effects of prenatal androgens on aspects of gender development. Increasing evidence confirms that prenatal androgens have facilitative effects on male-typed activity inte...
