Many studies use a Harberger triangle method to estimate the immigration surplus to the native born population and conclude that the benefit of immigration is very small in proportion to the size of the US economy and thus the United States does not to stand to lose much if immigration is further restricted. This calculation neglects the rent seeking costs that the US economy bears when immigration policy is politically determined. This study estimates the rent seeking losses that the US economy could suffer if immigration policy were reformed to further close the borders. 相似文献

To Patent or Not: Faculty Decisions and Institutional Success at Technology Transfer 总被引:1,自引:0,他引:1
We draw on qualitative data derived from field work on two university campuses to develop an explanation for widely disparate rates of new invention disclosure. We argue that faculty decisions to disclose are shaped by their perceptions of the benefits of patent protection. These incentives to disclose are magnified or minimized by the perceived costs of interacting with technology transfer offices and licensing professionals. Finally, faculty considerations of the costs and benefits of disclosure are colored by institutional environments that are supportive or oppositional to the simultaneous pursuit of academic and commercial endeavors. 相似文献

AbstractIn his book On Human Nature, sociobiologist Edward O. Wilson expresses many of the frustrations of natural scientists, complaining that the intellectual community has failed to recognize the importance of their contributions. He attributes this partly to the natural scientists' lack of literary ability and laments that even those who “step outside scientific materialism to participate in the [dominant] culture” have almost never been able “to close the gap between the two worlds of discourse.” But he directs his main criticism at those who work in the social sciences. He argues that they control the cultural establishment and that their reflections “are devoid of the idioms of chemistry and biology, as though humankind were still in some sense a numinous spectator of physical reality.” 相似文献
