We examine sources of productivity in bioscience research and graduate training in U.S. universities. For this purpose, we first identify the scientific publications cited on agricultural biotechnology patents, and then trace the citations back to the universities producing the cited research....

Many argued during the NAFTA debate that trade liberalization would favor Mexican over U.S. food processors, especially because of lax environmental laws south of the border. We find through an examination of profit functions that productivity growth in Mexico has outstripped that in the United...

The average quality of agricultural biotechnology patents appears to have declined substantially during the past two decades. This quality deterioration may reflect either a decline in the significance of new inventions or an increased use of patents as "protective thickets" against competitors'...

Life-science research has shifted rapidly from the public to the private sector, raising questions about government’s remaining role. We shed light on the issue by employing a dynamic investment-response model to examine the public’s impact on industry life-science research effort and...

A supply and demand model of the Israeli hotel industry is developed, distinguishing between its domestic and foreign sectors. Model simulations are employed to examine the impacts of war and terrorist incidents on tourist activity and hotel revenues. Foreign demand for Israeli hotel stays is...
