Citizens often misperceive the nature of risks they face and the impacts of alternative actions on those risks. For example, consumers may underestimate the probability of flood in their area, or they may underestimate the beneficial effect of passive restraints on the likelihood of automobile accident fatality. But recommendations that the government should mandate optimal purchases are often ignored by politicians or rejected in favor of direct public compensation. This paper uses some simple models of public choice to explain why other remedies are used; it explicitly accounts for the fact that the same ignorant consumer whose behavior would have to be constrained are the ones whom the politician must please. In a simple world-of-equals model, such consumer-voters may well favor the alternative devices of implicit mutual insurance and conditional payment. When voters are heterogeneous, the political equilibrium (if one exists) is shown to depend upon the distribution of voters by perceived net benefit of public action and of taxes. Public action may be least feasible exactly when it would do the most good. 相似文献

Barbaree HE 《Journal of interpersonal violence》2005,20(9):1115-1131
Seto and Barbaree reported the unexpected finding that adult male sex offenders who scored higher on psychopathy and exhibited better behavior in treatment were almost four times more likely to commit a new serious offence than other offenders once released. The present study reexamined this sample after a longer follow-up time using more complete recidivism data from a national police database. Although psychopathy continued to be a significant predictor of general and serious recidivism, treatment behavior was no longer related to either general or serious recidivism, and there was no statistically significant interaction between psychopathy and treatment behavior. Additional analyses ruled out the possibility that the differences between studies could be accounted for by the different average length of follow-up. A direct comparison of the two sources of recidivism data showed that differences in recidivism between subgroups were reduced by using the more complete recidivism data. 相似文献
