Whether one votes and how one votes   总被引:1,自引:0,他引:1  
Fort  Rodney  Bunn  Douglas N. 《Public Choice》1998,95(1-2):51-62
The aim of this paper is to determine if whether one votes effects the vote that is cast. Using an economic model of voting and observed voting results on nuclear power referenda, the answer is a resounding yes. Overcoming registration, turnout, and “roll off” hurdles dramatically increases the odds of voting against nuclear power. Indeed, participation swamps both economic and preference variables in the explanation of nuclear power voting outcomes. The lesson is that there is a structure to participation at the polls that should not be ignored by those interested in analyzing voting outcomes.  相似文献

Despite the vast coalition literature, pre-electoral coalitions have never been at the center of any systematic, cross-national research. Given their prevalence and potential impact on government composition and policies, this represents a serious omission in our knowledge of coalitions. I begin to remedy this situation by testing two hypotheses found in the literature on party coalitions. The first is that pre-electoral coalitions are more likely to form in disproportional systems if there are a sufficiently large number of parties. The second is that pre-electoral coalitions are more likely to form if voters face high uncertainty about the identity of future governments. These hypotheses are tested using a new dataset comprising legislative elections in 22 advanced industrialized countries between 1946 and 1998. The results of the statistical analysis support the first hypothesis, but not the second.  相似文献

This paper presents a theoretical framework and some empirical results showing that the level of foreign aid received reduces the supply of terrorist attacks by recipient countries, as does the recipient country’s level of education. Due account is taken of endogeneity problems in producing these results. They suggest that Western democracies, which are the main targets of terrorist attacks, should invest more funds in foreign aid with a special emphasis on supporting education.  相似文献

The flow of foreign direct investment into developing countries varies greatly across countries and over time. The political factors that affect these flows are not well understood. Focusing on the relationship between trade and investment, we argue that international trade agreements—GATT/WTO and preferential trade agreements (PTAs)—provide mechanisms for making commitments to foreign investors about the treatment of their assets, thus reassuring investors and increasing investment. These international commitments are more credible than domestic policy choices, because reneging on them is more costly. Statistical analyses for 122 developing countries from 1970 to 2000 support this argument. Developing countries that belong to the WTO and participate in more PTAs experience greater FDI inflows than otherwise, controlling for many factors including domestic policy preferences and taking into account possible endogeneity. Joining international trade agreements allows developing countries to attract more FDI and thus increase economic growth.  相似文献

This article compares Moscow’s and Washington’s foreign policies toward the Middle East in 1982 and 2008. In 1982, Moscow and Washington each had a distinct set of friends and foes. In 2008, Washington still has a distinct set of friends and foes, but Moscow has relatively good relations with all governments and most major opposition movements in the region—the only exceptions being Al Qaeda and its affiliates. It is argued that Putin’s policy toward the Middle East is not really aimed at displacing the U.S. in the region, but protecting Russia and Russian interests from Al Qaeda and its allies. Indeed, a continued American presence in the region serves to protect Russian interests in the region.

Fluoxetine is a selective serotonin reuptake inhibitor, commonly used for the treatment of a variety of psychopathological conditions. As such, fluoxetine may be expected to appear in clinical and forensic cases. Dermestes maculatus De Geer (Coleoptera: Dermestidae) has been recognized as a relevant component of the insect fauna associated with decomposing human and animal remains. Experiments were conducted to study the effect of fluoxetine on developing D. maculatus using two‐drug administration models: a non‐living animal model (pork muscle) and a living one (Sus scrofa L. pigs). We assessed the duration of immature stages and total life cycle, as well as morphological parameters (body length, cephalic width, and weight). The effect of fluoxetine was studied at an overdose concentration: In the non‐living animal model the drug was mixed with macerated pork muscle (2000 mg/kg) and in the living animal model, pigs were given the drug orally (833 mg/kg). A control was used for each model. Daily observations were performed from the beginning to the end of the experiments. GC‐MS was used for drug detection and quantification. There were no statistically significant differences in the duration of immature stages, life cycle, larval mortality, morphological parameters, or sex ratio, between treatment and control, regardless of the drug administration model. Given that fluoxetine had no detectable effect on the development of D. maculatus, detection of this drug in forensic situations would not compromise the accuracy of PMI estimations.  相似文献
