In this paper we show that costs associated with infractions of property rights, such as theft, can be reduced by imposing lower penalties on individuals who admit to such infractions and make restitution. We find that the socially optimal penalty on a confessed thief may be zero (complete amnesty) or even negative—a person may be given a reward for confessing a theft. This is because a thief's valuation of a good is generally lower that its valuation by its legal owner, and an amnesty permits the trade that such a difference in valuation makes calls for. It is interesting to note that the benefits of amnesties were apparently recognized in ancient times and they constitute part of Biblical Law. Moreover, such amnesties have also been informally incorporated into modern legal systems, wherein leniency (a form of partial amnesty) is generally shown to individuals who confess their infractions. 相似文献

This article presents a five‐part strategy to combat International Organized Crime (IOC). First, it establishes the need for ongoing assessments: what is known and what needs to be known about IOC, as well as what opportunities exist to influence its operations? Second, the US must establish a clear‐cut and annunciated policy and strategy that draws on the resources of its many relevant agencies as well as international cooperation. Third, the US should endeavour to lead an international effort to enhance law enforcement. Fourth, law enforcement alone will be inadequate. Containing and neutralizing IOC will require disruption activities as well. Fifth, there is a need for private‐sector education programs to prevent successful criminal enterprises. 相似文献

This study examined the association between officially recorded child abuse and neglect and adult mental health, substance use, and physical health outcomes. Data are from a longitudinal study of more than 30 years in which individuals were interviewed most recently in their mid—30s. Analyses consisted of group comparisons using chi-square tests for categorical variables and independent samples t-tests for continuous measures. Logistic and linear regressions controlled for gender and childhood SES, adult age, marital status, and education. Adults maltreated in childhood reported more symptoms of adult depression, anxiety, and more impairment due to mental and physical health problems. A higher percentage of those with maltreatment histories reported lifetime alcohol problems and appear at greater risk for substance abuse. Most findings of these bivariate analyses remained significant after accounting for gender and childhood socioeconomic status. Somewhat fewer significant results were observed after controlling for adult age, marital status, and education. 相似文献

Whether or not an unfettered market is the best solution to Africa's problems, the public service is both the subject and the object of reform. It is an arena of policy change and adjustment in economic management, as well as the locus of struggle over principles and patterns of administrative practice. Below we take empirical stock of the patterns and progress made in public service reform in Africa, a process characterized by cost containment and retrenchment. Then we examine what is entailed in a qualitatively different public service that well serves a liberal economy, concluding with observations on whether and how that might happen in Africa. 相似文献
