A broad paper by a Stanford University Business School labor economist explains why the bargaining structure a country has is less important than it used to be.
Stanford University Graduate School of Business faculty members have developed hard evidence of venture capital's singular role in nurturing startups. But venture capital firms are in danger of becoming too institutionalized. The study serves as an indirect warning that venture capital's special purpose should be preserved.
The current heat wave throughout the continental United States is straining the nation's aging power system, says an electrical and computer engineer at the University of Missouri-Rolla.
From braided hairstyles to the design of housing settlements, the geometric structures known as fractals permeate African culture. In a new book, an Ohio State scholar examines the unlikely pairing of this mathematical concept and the culture and art of Africa.
Across the country, state lawmakers have responded to citizen concerns and successfully created laws to protect consumers in managed care plans, according to "State Managed Care Laws: A State-by-State Review," the latest report from the National Conference of State Legislatures' Health Policy Tracking Service.
