Several U.S. states have supplemented traditional judicial review of local land-use regulation with a state affordable housing appeals system (SAHAS). Empirical evidence indicates that a SAHAS can increase the proportion of housing that is affordable to low- and moderate-income households. But some scholars have suggested that an effective SAHAS will ultimately backfire, by producing incentives to prohibit market-rate development, thereby rendering a state’s housing stock less affordable overall. We test this “backfire” hypothesis with a longitudinal comparison of single-family housing development from 1980 through 2007 in municipalities located in adjacent areas of Connecticut (which adopted a SAHAS in 1989) and New York State (which did not have a SAHAS during the study period). Contrary to the predictions of the backfire hypothesis, our fixed effects regression indicates that Connecticut's SAHAS was associated with increased single-family development relative to the New York State jurisdictions in our sample. This result suggests that a SAHAS can increase below-market rate and mixed-income development without impeding market-rate development.  相似文献

In recent years, a growing body of empirical research suggests that indiscriminate violence against civilian targets tends to carry substantial political risks compared to more selective violence against military targets. To better understand why terrorist groups sometimes attack politically suboptimal targets, scholars are increasingly adopting a principal-agent framework where the leaders of terrorist groups are understood as principals and lower level members as agents. According to this framework, terrorist leaders are thought to behave as essentially rational political actors, whereas lower level members are believed to harbor stronger non-political incentives for harming civilians, often in defiance of leadership preferences. We test this proposition with an original content analysis of terrorist propaganda videos. Consistent with the principal–agent framework, our analysis demonstrates statistically that terrorist leaders tend to favor significantly less indiscriminate violence than their operatives actually commit, providing unprecedented insight into the incentive structure of terrorist leaders relative to the rank-and-file.  相似文献

In this article, we present the results from a youth-led project on the voices and participation of children in state care in Ontario, Canada. The purpose of this project was for youth to share their voice about what they wish child protection workers and agencies could do to improve their experiences within the child protection system. Many youth in care in Canada and internationally report that their voices are not heard and that they are not involved in decisions involving their care. Seven themes were extracted from this voices of youth project asking child welfare workers and agencies to listen to [them] and believe [them], keep [them] informed and be honest, involve [them] in decisions, support [them], keep [them] connected,; ignite [their] passions, and don't give up on [them]. Suggestions from the youth involved in this project are offered on ways to create true and meaningful change in child welfare.  相似文献

This article is an attempt to provide a helicopter view of the influences and responses that have shaped the corporate public affairs function over four decades from non‐existence to an important and settled profession in Australia's major companies. It reflects the perceptions and experiences of an observer with a background in public administration, politics, academia, industry association leadership, and consulting to companies and industry organisations over that period. They are further informed by surveys and other studies conducted by the organisation supporting public affairs departments, the Australian Centre for Corporate Public Affairs (the Centre) since its inception in 1990. The article charts the emergence from two distinct, low level management silos—one supporting communications and the other, government affairs—to create an integrated strategic management function. The central story is of waves of innovation in concepts and practices, developed mainly overseas, being embraced with enthusiasm and becoming a dominant focus, before settling into the broad toolbox of public affairs. This occurred particularly in the period 1990–2005 during which the function took its shape. With such a broad and ambitious sweep, it is inevitable that bold generalisations begging exceptions must be made.  相似文献

Location efficient mortgage (LEM) programs are an increasingly popular approach to combating urban sprawl. LEMs allow families who want to live in densely populated, transit‐rich communities to obtain a larger mortgage with a smaller down payment than traditional underwriting guidelines allow. LEMs are premised on the proposition that homeowners in such “location‐efficient” areas can safely be allowed to breach underwriting guidelines designed to prevent mortgage default because they have lower than average automobile‐related transportation expenses and more income available for mortgage payments. This paper employs records of more than 8000 FHA‐insured mortgages matched with data on various measures of location efficiency to test this proposition. The results suggest that it does not hold and that LEMs—like other low‐down‐payment mortgage programs—will raise mortgage default rates. This cost must be weighed against any potential anti‐sprawl benefits LEMs may have. © 2001 by the Association for Public Policy Analysis and Management.  相似文献

We investigate the causality between corruption and income inequality within a multivariate framework using a panel data set of all 50 U.S. states over the period 1980 to 2004. The heterogeneous panel cointegration test by Pedroni (Oxf. Bull. Econ. Stat. 61:653–670, 1999; Econom. Theory 20:597–627, 2004) indicates that in the long run corruption and the unemployment rate have a positive and statistically significant impact on income inequality while a negative impact is found for real personal income per capita, education, and unionization rate. The Granger-causality results associated with a panel vector error correction model indicate both short-run and long-run bidirectional causality between corruption and income inequality.  相似文献

Transactional theories of development suggest that displaying high levels of antisocial behavior early in life and persistently over time causes disruption in multiple life domains, which in turn places individuals at risk for negative life outcomes. We used longitudinal data from 1,137 primarily African American urban youth (49.1% female) to determine whether different trajectories of aggressive and disruptive behavior problems were associated with a range of negative life outcomes in young adulthood. General growth mixture modeling was used to classify the youths’ patterns of aggressive–disruptive behavior across elementary school. These trajectories were then used to predict early sexual activity, early pregnancy, school dropout, unemployment, and drug abuse in young adulthood. The trajectories predicted the number but not type of negative life outcomes experienced. Girls with the chronic high aggression–disruption (CHAD) pattern experienced more negative outcomes than girls with consistently moderate levels, who were at greater risk than nonaggressive–nondisruptive girls. Boys with CHAD and boys with an increasing pattern had equal levels of risk for experiencing negative outcomes. The findings are consistent with transactional models of development and have implications for preventive interventions.  相似文献
