The article reviews the state of research on public-private partnerships (PPP) which, following a development in the Anglo-Saxon countries, in the past few years have been introduced as a policy tool in Germany as well. Based on a short conceptual and historical introduction, recent political science publications as well as contributions from economic, legal, and administrative scientists are systematized and critically assessed. This also includes a review of selected publications on PPP experiences in Britain. Finally, the paper discusses relatively neglected research issues, including methodological deficits as well as problems of input legitimacy.  相似文献

Baumgartner and Jones (1993) showed how radically new policies emerge on government agendas as a consequence of exogenous shocks to policy subsystems displacing privileged interests. But how do these policies evolve post-punctuation? In this paper, we present three different models of policy change. Policies may revert to the old status quo if displaced interests re-assert themselves, or they may be “locked-in” by new interests now reaping the benefits. Alternatively, they may incrementally change as lawmakers “learn” how to better meet target population needs, particularly by witnessing how other jurisdictions address similar problems. We test these models with data on change in state charter schools laws over time. We find that whether old status quos are overthrow, and the fate of charter policies when they are enacted, is influenced more by competing political interests, especially interest groups, than elite and public perceptions of broad systemic crises. Yet, we also find that changing demands on the state and learning from the successes and failures of neighboring states also play significant roles.  相似文献

This article examines the structure of nonprofit voluntary accountability and standard-setting programs, arguing that these programs can be understood as collective action institutions designed to address information asymmetries between nonprofits and their stakeholders. Club theory and the economics of certification suggest that such programs have the potential to provide a signal of quality by setting high standards and fees and rigorously verifying compliance. Such mechanisms can signal quality because higher participation costs may allow only high-quality organizations to join. The article examines the implications of signaling theory using an original dataset on the structure of 32 nonprofit accountability programs across the globe. While many programs set high standards for compliance, the key distinction between strong and weak programs is the use of disclosure or verification mechanisms to enforce compliance. Contrary to theoretical expectations, compliance standards and verification do not appear to be substitutes in creating stronger voluntary programs.

According to the democratic domino theory, increases or decreases in democracy in one country spread and "infect" neighboring countries, increasing or decreasing their democracy in turn. Using spatial econometrics and panel data that cover over 130 countries between 1850 and 2000, this article empirically investigates the democratic domino theory. We find that democratic dominoes do in fact fall as the theory contends. However, these dominoes fall significantly "lighter" than the importance of this model suggests. Countries "catch" only about 11% of the increases or decreases in their average geographic neighbors' increases or decreases in democracy. This finding has potentially important foreign policy implications. The "lightness" with which democratic dominoes fall suggests that even if foreign military intervention aimed at promoting democracy in undemocratic countries succeeds in democratizing these nations, intervention is likely to have only a small effect on democracy in their broader regions.  相似文献

A positive, statistical and economic significant relation between growth, income level and the Economic Freedom of the World (EFW) index has been amply documented. Most analyses, however, use OLS methods which, in the presence of endogenous variables do not establish causality and produce biased and inconsistent estimates. This paper uncovers the exogenous component of EFW using IV methods and finds a robust channel from economic freedom to prosperity. The findings, including instrument validity tests, support the importance of policies and institutions for development and warrants policy advice aimed at increasing economic freedom to foster prosperity.  相似文献

Social capital has attracted increasing attention in recent years. We use county-level and individual survey data to study how Wal-Mart affects social capital. Estimates using several proxies for social capital—such as club membership, religious activity, time with friends, and other measures—do not support the thesis that “Wal-Mart destroys communities” by reducing social capital. We measure exposure to Wal-Mart two ways: Wal-Marts per 10,000 residents and Wal-Marts per 10,000 residents aggregated over the years since 1979 to capture a more cumulative “Wal-Mart Effect.” We find that the coefficients on Wal-Mart’s presence are statistically insignificant in most specifications.  相似文献

The idea of radically extending average human life expectancy is an ancient one, but for most of human history exceedingly utopian. There is now, however, a revival of that idea, with some scientists and others arguing that it is possible and desirable. But the main problem with most of the life extension enthusiasm is that it is based almost entirely on the desire of some individuals to make it happen. The social consequences of success of such a venture are, however, either ignored altogether or dismissed on the grounds that any problems can be dealt with. In the end, none of our present human and social problems would be helped by radically longer lives and no obvious social benefits have been advanced to support it.

Changes in immigration laws over the last three to four decades have given rise to unprecedented numbers of undocumented children. However, as others have argued, policies regarding the control of undocumented migration have had deleterious effects on undocumented children and their basic access to social rights. Undocumented youth in the United States can legally attend K-12 education, but cannot legally work, vote, receive financial aid, or drive in most states. Their situation calls for a reexamination of immigration laws and a recasting of the frame that has been used to promote their inclusion.
