Over the past two decades states have significantly increased their use of competitive bidding to purchase health and social services from private agencies. Competitive contracting is thought to facilitate program administration, to reduce costs, and to increase the quality of delivered services. We evaluate these claims in light of Massachusetts' experience with competitive contracting for mental health care. We find that few of the expected benefits are achieved. In practice, supposedly competitive bidding systems often degenerate into administratively complicated negotiations between the state and private monopolies. This results in higher costs and lower quality of services. In light of this negative assessment, three strategies for reform are proposed and evaluated. 相似文献

In Garcia v. San Antonio Metropolitan Transit Authority (1985),a majority of the U.S. Supreme Court's justices did violenceto the principles of the U.S. Constitution by leaving the statesto take their Tenth Amendment complaints to the Congress. Inabdicating their proper constitutional role, the majority ofjustices ignored history, political realities, and constitutionalprinciple. The Constitution's institutional arrangements, ofwhich federalism is a key component, are an intrinsic part ofthe constitutional scheme by which government power is limitedand individual rights are protected. 相似文献

Abstract. The factors underlying patterns of partisan preference in Greece have been the subject of fairly little systematic analysis. This article uses data from a 1980 Euro-Barometer survey, the first to include a Greek sample, to outline the structure of the Greek partisan universe. A number of demographic variables – age, family income, education, occupation, sex, size of community, and household status – together with attitudinal variables regarding both foreign and domestic policy issues are tested as predictors of party identification. The multivariate statistical technique of discriminant analysis is used to measure the relative importance of these predictor variables in influencing the direction of party preferences. The findings show that attitudinal factors for the most part are more important than demographic traits. A stepwise analysis provides a rankordering of the strongest explanatory variables. The impact of recent political and historical developments on the party system in Greece is discussed. 相似文献
