The emergence of behavioral public administration has led to increasing calls for public managers and policy makers to consider predictable cognitive biases when regulating individual behaviors or market transactions. Recognizing that cognitive biases can also affect the regulators themselves, this article attempts to understand how the institutional environment in which regulators operate interacts with their cognitive biases. In other words, to what extent does the “choice architecture” that regulators face reinforce or counteract predictable cognitive biases? Just as knowledge of behavioral insights can help regulators design a choice architecture that frames individual decisions to encourage welfare-enhancing choices, it may help governments understand and design institutions to counter cognitive biases in regulators that contribute to deviations from public interest policies. From these observations, the article offers some modest suggestions for improving the regulatory choice architecture.  相似文献

The global defense industrial sector is a remarkably accurate indicator of the distribution of power in the post-Cold War international system. However, the defense industrial sector as a policy tool has received relatively little scrutiny, even though it not only reflects the international order, but also provides the United States with the ability to influence the foreign policy behavior of other states. The defense industrial sector is a powerful, if undervalued, diplomatic tool in the United States’ political arsenal.  相似文献

This paper describes several dimensions of the cost of the U.S. response to the threat of terrorism. Following an evaluation of the nature and magnitude of the threat of terrorism against the United States, the paper describes the restrictions on our civil liberties, the fiscal and other costs of the major homeland security measures, the fiscal cost of programs that make no contribution to the defense against terrorism but are rationalized on that ground, and the effects on our language and the potential for civil discourse of an extended defense against terrorism.  相似文献

What drives policymakers to put the interests of others above their own? If human nature is inherently selfish, it makes sense to institutionalize incentives that counter decision makers' temptations to use their positions to benefit themselves over others. A growing literature rooted in evolutionary theories of human behavior, however, suggests that humans, under certain circumstances, have inherent predispositions towards “representational altruism,” i.e., to make an authoritative decision to benefit another at one's own expense. Drawing on Hibbing and Alford's conception of the wary cooperator, a theoretical case is made for such behavioral expectations, which are confirmed in a series of original laboratory experiments.  相似文献

In the early 1970s, Grand Canyon National Park intended to designate its land to “Wilderness,” including the controversial Colorado River corridor. However, by the end of the 1970s the potential for Wilderness designation was off the table, and would never seriously return for genuine consideration. Using Schattschneider's model of conflict, we explain how the organization of this conflict privileges the “causal story” of Wilderness opponents, and therefore why the canyon is not designated. It is our contention that members of Congress will not stand forward to support Wilderness designations without simultaneously providing benefits for extractive land use because (1) congressional representatives are more penalized for supporting than opposing Wilderness designations, (2) Wilderness advocacy groups do not pressure congressional delegates as firmly as opposition groups, and (3) key local congressional members are not likely to see Wilderness as a salient issue worth the risk of negative exposure. If these findings hold, the implication is that we may have reached the end of significant Wilderness designations in highly visible areas, unless critical aspects in land use conflict change.  相似文献

Numerous accounts reveal that congressional leaders often secure “hip‐pocket votes” or “if you need me” pledges from rank‐and‐file legislators. These are essentially options on votes. Leaders exercise sufficient options—pay legislators to convert to favorable votes—when those options will yield victory. Otherwise, they release the options. A model shows that this optimal strategy for leaders produces many small victories, few small losses, and losses that are, on average, larger than victories. We find precisely these patterns, hence strong evidence for vote options, in Congressional Quarterly key votes from 1975 through 2001 and in non‐key votes from the 106th Congress (1999–2000).  相似文献

This concept paper presents a theory of environmental scarcity developed byHomer-Dixon. Homer-Dixon developed a model to describe the consequences of scarcity for sub-national violence in third world countries. This paper hasfour interrelated purposes. First, it presents the model of scarcity developedby Thomas Homer-Dixon in 1999. Second, it assesses the way in which the scarcity model contextualizes criminal justice and criminology research, andby extension, how research in crime and justice processes can broaden the scarcity model. Third, it applies elements of the model to the United States,a goal that represents a generalization of the model from third-world to first-world settings. Fourth, it presents a particular case, the migrationof African-Americans from the rural South to urban centers in the 1950s and1960s and consequent inner-city violence in the 1960s, that displays manyelements of the environmental scarcity model.  相似文献

In 1991 the FCC implemented a price cap plan for local exchange carriers' interstate access service designed to deal with the regulatory boundaries problem arising from the breakup of AT&T in 1984. The experience with the price cap plan demonstrates the difficulty of predicting productivity growth accurately and makes clear that regulators cannot depend upon a pure price cap plan to keep prices within a reasonable range of costs. With periodic reviews to readjust plan parameters, however, a price cap plan can maintain the rate-of-return close to the target rate-of-return without diminishing the price cap plan's incentives for efficient production. A simple method of recalculating the X-factor based on the rate-of-return over the previous three years worked well in simulations. If this procedure had been used over the price cap period 1991 to 2000, prices would have been 20 percent lower and expenditures on LECs' telecommunications service subject to a price cap would have been $3.8 billion lower.  相似文献

The adjustment problems associated with sexual abuse, physical abuse, psychological maltreatment, neglect, and witnessing family violence during childhood were examined in three studies. Study 1 demonstrated significant overlap between maltreatment types in parent reports (N = 50) of maltreatment experiences of their child aged 5–12 years. Parental sexual punitiveness, traditionality, family adaptability and family cohesion significantly predicted scores on 4 maltreatment scales and children's externalizing behavior problems. Level of maltreatment predicted internalizing, externalizing, and sexual behavior problems. In Study 2, significant overlap was found between adults' retrospective reports (N = 138) of all 5 types of maltreating behaviors. Parental sexual punitiveness, traditionality, family adaptability, and family cohesion during childhood predicted the level of maltreatment and current psychopathology. Although child maltreatment scores predicted psychopathology, childhood family variables were better predictors of adjustment. Study 3 demonstrated that child maltreatment scores predicted positive aspects of adult adaptive functioning (N = 95).  相似文献
