This paper investigates infrastructure investment in markets where regulation is subject to varying degrees of manipulation by elected politicians. Based on a model of price regulation in a market with increasing demand and long-term returns on investment we construct a multi-period game between a service provider, consumers with voting rights and elected decision makers. In each period the con...

This longitudinal study tracked 1,110 adolescents identified as mathematically precocious at Age 13 (top 1%) with plans for a math science undergraduate major. Participants’ high school educational experiences, abilities, and interests predicted whether their attained undergraduate degrees were within math science or nonmath nonscience areas. More women than men eventually completed undergradua...

As universities and research hospitals move increasingly toward translational research and encouragement of entrepreneurship, more attention must be paid to management of conflicts of interest (COIs) if the public trust is to be maintained. Here, we describe COI policies at two institutions that aim to structure an academic environment that encourages innovation while protecting academic values.

The purpose of this study was to gather and analyze information about the ICOI policies ...
