The literature on incumbency advantage has focused on margin as an indicator for electoral security. But while electoral margin is a goodex ante measure, it is a poorex post measure of security. Further, existing work has not integrated the choice of retirement with changes in the level of security. To improve the specification and definition of “marginality”, a multinomial LOGIT model is proposed where the dependent variable is categorical. Account is therefore taken of all the ways a Representative's term in office can end, including reelection, defeat, retirement, or pursuit of other office. The sample includes all U.S. Representatives elected for the first time between 1948 and 1978. The results indicate that (1) margin in the previous election is a significantex ante proxy for the probability of electoral defeat, and (2) while the electoral safety of all incumbents in the House has been increased, the increases are greater for members elected for the first time in the period since 1965. 相似文献

Secrecy in the voting process eliminated an important motivation for voting. No longer able to verify the voters' choices, political parties stopped offering payments in return for votes. Within the rational voter framework, it will be shown that these payments were a prime impetus for people to vote. Without a vote market to cover their voting costs, many voters were rational to stay away from the polls. This hypothesis is supported through a series of empirical tests culminating in a multivariate legislative regression. When other electoral laws are controlled for, the secret ballot accounts for 7 percentage points lower Gubernatorial turnout. 相似文献

This article presents a conceptual framework that illustrates four distinct types of accountability environments facing public managers. The framework is used as a heuristic tool to examine the broad facts and contexts surrounding the bankruptcy of the Orange County, California investment pool. The framework also suggests management philosophies and strategies that are appropriate for each type of accountability environment. 相似文献

Several conclusions may be drawn from the information we have presented here. First and without doubt, the University of Chicago is by far the most dominant force overall, and is particularly so with respect to the production of pages and papers published in the Journal of Law and Economics. The George Mason-Virginia Tech influence is strong with respect to Public Choice, but is not, in our opinion, dominant.One does not necessarily need to be located at a large, research-oriented school in order to publish in either journal, but these schools are the source of most contributions. This is particularly true of the JLE but significantly less so for PC. The source of contributions is very broad, but top 50 institutions account for the lion's share. Contributions by persons employed at foreign institutions are important, particularly for PC. 相似文献

Voter turnout in the United States is much lower than in almost all other democratic countries. This has been interpreted as a symptom of popular alienation from the political system, suspicion of politicians, and pessimism about the consequences of political activity. When these perspectives are measured directly, however, it is clear that Americans score very low on almost every item. Indeed, there is no relationship between political con- tentment and turnout. Turnout does not reflect international variations in acceptance of politicians or the political system. Rather, it responds to variations in the bureaucratic steps required to cast a ballot. The United States is one of a handful of countries that require a separate step–registra- tion–before the citizen can vote; and with the partial exception of France it is the only country in which the individual rather than the state bears the responsibility for registration. 相似文献
