This paper develops an identification strategy to generate unbiased estimates of Internet usage spillovers using a unique data set of US households. This strategy addresses the effects of variables that affect consumers' decisions but are unobservable to the researcher that lead to biased estimates. The estimator developed here examines changes in household behavior over time and uses county level instrumental variables for county level spillover measures.Multiple potential sources of learning are identified including those from the household's locality, from educational Internet subsidies, and from universities. There is general support for all sources, but the locality and subsidy results are both more robust and larger. These findings directly address the policy relevance of these spillover sources and they have implications for policies to encourage Internet use as well as for identification strategies for the effects of the Internet on behavior. 相似文献

The remarks that follow are made with regard to the behavior of leaders whose self-image is threatened by a variety of conditions comprising the world problematique. Of all those conditions, surely those associated with violence and warfare are the most threatening. I would speculate, therefore, that what I've written here is especially pertinent for deliberations on how to encourage peace and disarmament.While these remarks are focused on the behavior of leaders—especially those in government—they can hold, too, for those in the public who identify with those leaders…itself another psychodynamic process. Of course, the public's contexts differ so the degree of threat and response will differ, too. This is a matter for further attention.Moreover, self-images are usually rich in content and while some aspects are threatened, others may not be or, indeed, may be attracted by new rational ideas. The resultant struggle within the psyche complicates the overt expression of these unconscious conflicts.But these dynamics mirror those comprising the problematique, especially its expression around issues of war and peace. Therefore, psychodynamic matters deserve as much attention and utilization as we now give to conventional, indeed, often ritual means, masquerading as rationality, for dealing with violence and armaments. 相似文献
