We know relatively little about the economic effects of “insignificant” rules because they are not typically analyzed. Yet, these rules could be cumulatively important. We provide an economic analysis of one proposed rule to control hazardous air pollutants, which is not considered to be economically significant. This rule is of particular interest because it is one of the first in a long series of rules that Environmental Protection Agency (EPA) will consider for limiting hazardous air pollutant emissions. Our analysis suggests that the proposed controls that EPA has considered are not likely to pass a benefit–cost test. We recommend that an agency base its decision to allocate additional resources to benefit–cost analysis on the expected value of the improved information. In addition, agencies should consider applying a rule of thumb that would specify a threshold level of risk reduction that needs to be achieved before some kinds of regulation are considered. 相似文献

Using panel data that track individual students from year to year, we examine the effects of charter schools in North Carolina on racial segregation and black‐white test score gaps. We find that North Carolina's system of charter schools has increased the racial isolation of both black and white students, and has widened the achievement gap. Moreover, the relatively large negative effects of charter schools on the achievement of black students is driven by students who transfer into charter schools that are more racially isolated than the schools they have left. Our analysis of charter school choices suggests that asymmetric preferences of black and white charter school students (and their families) for schools of different racial compositions help to explain why there are so few racially balanced charter schools. © 2006 by the Association for Public Policy Analysis and Management. 相似文献

The interaction of welfare and child support regulations has created a situation in which child support policy's incentives that discourage unwed fatherhood tend to be stronger than its incentives that encourage unwed motherhood. This suggests that more stringent child support enforcement creates incentives that reduce the likelihood of nonmarital childbearing, particularly among women with a significant chance of needing public assistance in the event of a nonmarital birth and their male partners. We investigate this hypothesis with a sample of women from the Panel Study of Income Dynamics, to which we add information on state child support enforcement. We examine childbearing behavior between the ages of 15 and 44 before marriage and during periods of non‐marriage following divorce or widowhood. The estimates indicate that women living in states with more effective child support enforcement are less likely to bear children when unmarried, especially if they are young, never‐married, or black. The findings suggest that improved child support enforcement may be a potent intervention for reducing nonmarital childbearing. © 2006 by the Association for Public Policy Analysis and Management. 相似文献

The rapidly changing political, economic, and security policies in the Soviet Union and Eastern Europe in late 1989 and 1990 have added to the complications faced by Chinese leaders since they decided to suppress the unprecedented large-scale pro-democracy demonstrations in Chinese cities in spring 1989. These changes had an obvious “ripple effect” in China, encouraging prodemocracy forces and alarming Chinese leaders. They attracted strong positive attention from the developed countries of the West and Japan, and international financial institutions and businesses. This came at the indirect expense of China. And they accelerated changes in world politics (especially in U.S.-Soviet relations) and in the politics of government decision making in the West that promised to reduce China’s relative influence in world affairs in the 1990s. The prospect of reduced influence abroad and curbed economic contacts did not appear to be sufficient cause for Beijing leaders to markedly change existing policies. Chinese leaders in mid-1990 appeared focused on issues of internal political power at a time of leadership transition. Significant changes in policy appeared most likely to await leadership changes as Deng Xiaoping and other aged leaders die or are incapacitated. 相似文献

Generous Commonwealth funding before self-government in 1989 meant that the ACT enjoyed high government expenditures and low taxation compared with the states. Self-government meant a transition to normal state funding, ultimately involving substantial reductions in Commonwealth grants. Successive governments aligned taxes with other jurisdictions, but failed to reduce expenditures, which remained well above Commonwealth Grants Commission (CGC) assessments of levels necessary to provide a standard level of services. The fiscal position — however measured — has worsened. The transition to normal funding has been unsuccessful and, without the necessary adjustments, a heavy burden will be placed on future Canberrans. 相似文献

Although there has been evidence for some time of a sex difference in depression, relatively little research has examined the developmental process by which women come to be at greater risk than men for depression. In this paper, the developmental pattern of depressed affect is examined over early and middle adolescence, with a special focus on the patterns of boys as compared to girls. In addition, a developmental model for mental health in adolescence is tested for its power in explaining the emergence of gender differences in depression. Longitudinal data on 335 adolescents randomly selected from two school districts were used to test the hypotheses. Results revealed that girls are at risk for developing depressed affect by 12th grade because they experienced more challenges in early adolescence than did boys. The sex difference in depressed affect at 12th grade disappears once early adolescent challenges are considered.This research was supported in part by grants MH30252/38142 to A. Petersen.
