Despite a comparative disadvantage vis-à-vis whites in resources like education that often are considered to lead to political sophistication, African Americans show signs of being a rather politically sophisticated group of people. Given that better educated people are much more likely than those with less education to see larger differences between Democrats and Republicans, the propensity for blacks to perceive larger differences between the parties, both in general and on specific issues, is striking. This puzzle is explained by the fact that education has a huge impact on seeing partisan differences for whites, but not for blacks. That this understanding of the structure of American politics has so completely penetrated black public opinion is quite remarkable. Strength of partisanship, and to a lesser degree, racial consciousness, appear to be largely responsible for blacks (particularly less educated blacks) perceiving such stark party differences.  相似文献

Federalism is first examined as an ideal-type political orderas possibly emergent from initial constitutional agreement amongmembers of a prospective political community. This abstractedand nonhistorical analysis is followed by an examination ofthe possible applicability of the federalist ideal as the basisfor reform in specific historical-institutional settings. Thedirection of constitutional change toward effective federalismis discussed, with the devolution of political authority fromcentralized structures carefully distinguished from the limitedconcentration of authority from previously autonomous politicalunits.  相似文献

Numerous laboratory experiments have investigated the performance of several processes for providing public goods through voluntary contributions. This research has been able to identify features of the institution or environment which are reliably likely to produce outcomes “close” to the free riding outcome or “substantially” greater than the pessimistic prediction of standard models. One such feature is the “marginal per-capita return” (MPCR) from the public good. Various authors have altered MPCR between groups or for an entire group at the same time. The experiments reported here address a different question, “What would happen if, within a group, some persons faced a ‘high’ MPCR while others faced a ‘low’ MPCR?”  相似文献

This paper empirically investigates the economic and political factors that have influenced annual Corps of Engineers water resource spending. Despite the common view that “pork barrel” spending is economically unjustified and purely politically motivated, economic factors have been important in determining water resource spending. From 1865–1920, economic development and industrialization increase spending, and from 1921–1988, spending appears to be counter-cyclical. There is also evidence that majority parties control spending levels in the post-Civil war period, while in recent times, legislators act under a norm of “constrained universalism” and are influenced by the costs to their constituents of increased spending.  相似文献

A transaction-based approach to policy intervention is presented. The approach overcomes a number of weaknesses in current approaches to policy intervention. The approach involves three main conceptual elements: transactions, transaction governance mechanisms, and governance principles. The transaction is taken to be the basic unit of analysis. Profiles of transactions vary along a number of transaction dimensions. Transaction governance mechanisms - such as, for example, government service, regulation, contracts, vouchers, markets, taxes, and self-service - are each suitable for governing transactions having particular profiles. A mechanism will fail when used to govern transactions not fitting the profile. Governance principles are criteria or expectations - for example, efficiency, justice and liberty - used to judge how well a mechanism fulfills or achieves important societal goals. Specific choices of governance mechanisms (from the set that are technically feasible) therefore should be made according to how well they satisfy these governance principles. Public high school education is used as an example to illustrate the approach. A number of conclusions are offered.This is a revised version of a paper presented at the Annual Meeting of the American Society for Public Administration Portland, Oregon, April, 1988.  相似文献

Eliminating the earnings test will have different effects on the work effort of persons aged 65-69, depending on whether or not they are currently working or currently receiving Social Security benefits. This article reviews the development of the earnings test and examines the theoretical implications on work effort of removing the test for members of this age group. It looks at the Current Population Survey (CPS) data to determine how many persons aged 65-69 have characteristics that can be identified with groups that would theoretically increase, decrease, or not change their work effort should they no longer be subject to the earnings test. This analysis suggests that at least 80 percent, and perhaps more than 90 percent, of the 9.7 million persons aged 65-69 will not change their level of work effort if the earnings test is eliminated. Individuals who would modify their hours worked and earnings are fairly evenly split among those who would increase, decrease, or have an undetermined direction of change in their work effort.  相似文献

The recent Supreme Court decision in Webster v. Reproductive Health Services giving more discretion to states to regulate abortion has led to speculation concerning which states might move to limit abortions. Medoff (1989) attempts to predict how state legislatures might vote on state-level abortion legislation by examining the 1983 Senate vote on the Hatch/Eagleton Amendment. We expand upon Medoff's analysis by incor- porating recent developments in agency theory as it applies to the political agents (i.e., Senators) in the empirical model. The results demonstrate that accounting for Senatorial "shirking" and state ideology substantially im- proves the predictive ability of the model for the Senate abortion vote. The predicted votes of the state's Senators, after eliminating the effects of apparent Senatorial shirking, are used to infer the likelihood of state-level legislation substantially restricting abortion. We compare these results to a base model that ignores the issue of shirking and find increased predict- ability and several differing results.  相似文献
