Whether one votes and how one votes 总被引:1,自引:0,他引:1
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

This note evaluates relative ability of the proximity and recently proposed directional variants of the spatial model of voter choice to account for candidate evaluations in US presidential elections contested between 1980 and 1992. I do this by estimating a statistical model that represents voter preference for a candidate as a weighted average of proximity and directional components. The analysis corroborates previous studies supporting the directional model, but illustrate that these results are sensitive to statistical specification. Alternative methodological specifications favor a mixed directional-proximity model and the traditional distance representation. 相似文献

In colonial America, land acquired new liquidity when it became liable for debts. Though English property law maintained a firm distinction between land and chattel for centuries, in the American colonies, the boundary between the categories of real and personal property began to disintegrate. There, the novelty of easy foreclosure and consequent easy alienation of land made it possible for colonists to obtain credit, using land as a security. However, scholars have neglected the first instances in which a newly unconstrained practice of mortgage foreclosure appeared—the transactions through which colonists acquired land from indigenous people in the first place. In this article, I explore these early transactions for land, which took place across fundamental differences between colonists’ and native communities’ conceptions of money, land, and exchange itself. I describe how difference and dependence propelled the growth of the early American contact economy to make land into real estate, or the fungible commodity on the speculative market that it remains today. 相似文献
