What are the differences between the public and private sectors as well as their interrelationships in light of the recent financial crisis? Has the global economic crisis fundamentally shifted the boundaries between the two sectors? This essay examines the nature and extent of the shift. The authors present an analysis of the Troubled Asset Relief Program (TARP) to highlight the massive transformations that are taking place and to introduce lessons for future policy initiatives. Between financial rescue missions and the economic stimulus program, government spending accounts for a bigger share of the nation’s economy—26 percent—than at any time since World War II. The government is financing 9 out of 10 new mortgages in the United States. If you buy a car from General Motors, you are buying from a company that is 60 percent owned by the government. If you take out a car loan or run up your credit card, the chances are good that the government is financing both your debt and that of your bank. —Edmund Andrews and David Sanger, New York Times, 2009 相似文献

Concerns over rising college tuition and slow economic growth have brought renewed attention to the role of federal and state financial aid programs in opening access to education. Despite a large body of literature examining the effects of grant aid on four‐year and public two‐year college enrollment, for‐profit colleges—particularly the vast majority that offer two‐year degrees and certificates—have largely been ignored. Using panel data methods and a new administrative data set of for‐profit colleges operating in California between 1989 and 2003, I assess the impact of the federal Pell Grant program, the G.I. Bill, and California's Cal Grant program on the net number of for‐profit colleges per county. The results suggest that for both Pell and Cal Grants, increases in the per‐student maximum award encourage for‐profit entry. This relationship is particularly strong in counties with high adult poverty levels, where more students are eligible for aid. Further, these gains in the private sector do not appear to come at the expense of the public sector. Rather, public community colleges also experience enrollment gains as the generosity of Pell and Cal Grants increases, although this reaction appears to be weaker than the reaction of for‐profits. © 2010 by the Association for Public Policy Analysis and Management. 相似文献

We review the history of gaming and its taxation in the U.S., particularly in regard to the idea of “sin taxes” which were often presented as policy instruments intended to control problem gamblers. The review suggests that raising taxes neither encourages moderation nor replaces negative external costs. We follow the review with a socioeconomic impact analysis of a proposed four percent Federal Gaming Tax by simulating its impact on Clark County, Nevada for the period 1995-2004 using a large scale econometric multi-regional model. Clark County is of interest because it is where Las Vegas is located. The analysis reveals that the proposed tax would lead to a measurable decline in Clark County's jobs, population, disposable income, and total industrial during the forecast period. By 2004, total industrial output would be 1.3 percent lower under the proposed tax and Clark County would experience a loss of $1.39 in real disposable income for every gaming tax dollar collected by Federal Government. These reductions, coupled particularly with the loss of thousands of jobs in Las Vegas area hotels/casinos predicted by the analysis suggest that increased demands on social services in Clark County would result. These findings, together with the lack of evidence that raising taxes would promote moderation or reduce external negative costs, lead us to argue that excise taxes represent an unattractive option. 相似文献

As climate change continues to increase both the frequency and intensity of environmental hazards and disasters, the need for a cohesive national mitigation policy grows. As the environmental federalism scholarship indicates, the inherent tension in federal, state, and local policy implementation highlights that despite a national need, environmental quality is a local public good. To complicate matters, there is disagreement about the optimal level of decision-making regarding the adoption and implementation of environmental policy. This study addresses this gap by considering the role of policy ambiguity and conflict in policy implementation. The analysis relies on primary qualitative data collected from open-ended interviews with 22 local government officials in 12 municipalities following Hurricane Harvey. Through the lens of policy ambiguity and conflict, we find confirmatory support for the idea that policies with less ambiguous goals are more likely to be implemented. Furthermore, we find that policy conflict arises when local governments perceive there is little for the community to gain by implementing the federal program. Thus, the level of protection afforded to citizens varies greatly between communities and is influenced heavily by politics. This research supports the Ambiguity-Conflict Model of policy implementation, an oft-cited but rarely tested theoretical framework for assessing the intergovernmental politics of policy implementation. It also demonstrates the barriers to local implementation of federal environmental policy in a nested system of government. 相似文献

Personality, psychopathology, and motives of 44 surviving offenders committing mass murder in Germany over 25 years (1984–2009) were analyzed using court files and psychiatric expertises. Initially, 123 mass murders in Germany were detected in the time period 1980–2010 (inclusive deceased offenders). Using a data entry form based on ViCLAS (Violent Crime Linkage Analysis System), we categorized the 44 surviving mass murderers into three prototypes using the ‘TwoStep Cluster’-method (separation of the offenders in different groups depending on their similarity of specific items): 1. Narcissistic or aggressive men suffering from addiction or affective disorder, committing mass murder out of rage/hate when being intoxicated by alcohol, 2. Psychotic offenders with schizophrenia and comorbid substance abuse. 3. Aggressive, narcissistic or anxious adolescents, half of them suffering from affective disorder or ADHD, committing mass murder out of rage/hate. Not included are such events where the offenders died and therefore no court files or psychiatric expertises were available. Classification and subtyping of the offenders’ personalities and psychopathological conditions might help to improve the chances for an early detection of persons at risk. 相似文献
