Through a field experiment and audit study, we test how the electoral calendar affects the use of local economic development policies. We explore how electoral timing along with local political institutions and party composition affect local governments’ offers of investment incentives to outside firms. We legally incorporated a consultancy and, on behalf of a real investor in manufacturing, approached roughly 3,000 U.S. municipalities with inquiries. The main experimental results show no greater tendency to offer incentives for investment anticipated prior to than after elections—a null result that is estimated with high precision. Limiting the sample to municipalities that specialize in manufacturing, the relevant subgroup, suggests that election timing matters in this most likely set of locales. Some observational findings include additional evidence on how direct elections of executives and partisanship correlate with incentive offers.  相似文献

Legal context. Some state legislatures are considering billswhich would require those applying for a driver’s licenceto provide one or more biometric identifiers. The US federalgovernment is tending towards eavesdropping on conversationsand investing in data mining efforts while on the other handanti "big-brother" technologies are also emerging to counterthis trend and protect privacy. The demand for technology toprotect privacy will no doubt increase as the demand for defenceand security spending increases. We also live in a world wherebioterrorist acts are a constant threat and therefore demandfor biological detection devices and nanotechnology is growingdaily. Key points. Current technology advances in biometrics, surveillance,biological detection and nanotechnology can be used both toprotect and to jeopardize the security and privacy of individuals.As such, the importance of intellectual property in these areascannot be underestimated. Practical significance. Companies are advised to ‘go onthe offensive’. All companies should aggressively protecttheir core technology in numerous facets such as patent protection,copyright, trade marks and trade secrets. In the high tech arenathis is especially important because the demand for securityand privacy necessitates the development of advanced applicationsand in turn the quality of protectable IP for the companiesthat develop the technology increases. Additionally, companiesshould also pursue an offensive strategy that includes analyzingemerging standards and competitor focus so that they can acquirea competitive advantage or secure cross-licensing of another’stechnology.  相似文献

The objective of this article is to find middle ground between the supporters and opponents of biotechnology by perpetuating the existing legal compromise pertaining to the complete range of health and welfare doctrines relevant to the biotechnological industry. The author aspires neither to add to nor detract from this liberal democratic consensus, but to preserve its constitutive balance between positivism and natural law and over-regulation and under-regulation in the hopes of stabilizing new political fault lines developing around the few biotechnological innovations already grabbing headlines. The most feasible solution is to extend the existing liberal democratic compromise with respect to equal protection, reproductive rights, the First Amendment, human subject experimentation, patent law, and parental rights. This includes banning or monopolizing certain biotechnologies and extending substantive special respect to the ex vivo living human embryo. Biotechnology must not be left to regulate itself.  相似文献

Those interested in political phenomena such as voting havefound random utility models, originally developed for decisionssuch as transportation choice, especially attractive, as theunderlying model can yield a statistical model with a few simple,realistic assumptions. Unfortunately, such models have provendifficult to apply to situations with more than two votes andthree alternatives or an unknown cutpoint. Additionally, aswe show, standard applications of such models to voting, whileproducing consistent parameter estimates, yield standard errorsthat are too small and, due to a failure to employ all relevanttheoretical information, biased ideal point estimates. We specifya general model applicable to any number of votes and alternatives,with correct standard errors and unbiased ideal point estimates.We apply this model to a number of cases studied by previousscholars involving legislative voting over the minimum wage:(1) when there are two votes and two known cutpoints (K. Krehbieland D. Rivers, American Journal of Political Science, 1988,32, 1151–1174); (2) when there are three votes and threeknown cutpoints (J. Wilkerson, American Journal of PoliticalScience, 1991, 35, 613–623); and (3) when there are threevotes but where one cutpoint is unknown given a lack of knowledgeabout the impact of a policy (J. Wilkerson, American Journalof Political Science, 1991, 35, 613–623) or the possibilityof sophisticated voting (C. Volden, Journal of Politics, 1998,60, 149–173). We show that in various contexts our analysisimproves on existing methods, yielding consistent and efficientideal point estimates and a better-fitting model with improvedpredictive accuracy.  相似文献

Eliminating racial and ethnic disparities in health status and health care, a major focus of Healthy People 2010, remains on the national agenda and among the priorities for the administration of President George W. Bush. Even though the elimination of racial and ethnic health disparities challenges the whole nation, individual states are on the front line of many initiatives and are often the focus of important policy efforts. In addition, it is important to focus on states because they are already responsible for much of the health and public health infrastructure, and several states have developed initiatives dating back to the release of Margaret Heckler's report on the gaps in health outcomes by race in 1985. This article makes the case for an outcome-oriented approach and provides a summary of lessons learned based upon preliminary investigations into constructing and applying two indices, the disparity reduction profile to measure effort and the disparity index to measure outcomes.  相似文献

In 1981, states, for the first time, were given an option to restructure the AFDC welfare program and require recipients to work in exchange for benefits. States have acted on this opportunity to introduce workfare or work requirements in a climate of polarized discussion and limited information. This paper summarizes the findings available from the pre-1981 demonstrations on the feasibility, impact, and cost-effectiveness of this approach. The authors conclude that these early demonstrations and evaluations provide very limited guidance to program administrators. The paper describes briefly a five-year social experiment currently under way in nine states to address the critical open policy questions through comprehensive process, impact, and benefit-cost studies.  相似文献
