The timing of the decision of local governments to adopt a local sales tax is explored in a duration model with time‐varying covariates. Our framework suggests a set of factors associated with the decision to adopt a local sales tax and we find empirical support for these factors. We also consider whether the adoption by one jurisdiction depends on the adoption by neighboring jurisdictions and find empirical support for interdependency of behavior.  相似文献

We examine whether gang membership is associated with higher levels of delinquency because boys predisposed to delinquent activity are more likely than others to join. We use 10 years of longitudinal data from 858 participants of the Pittsburgh Youth Study to identify periods before, during and after gang membership. We build on prior research by controlling for ages and calendar time, by better accounting for gang memberships that occurred before the study began, and by using fixed effects statistical models. We find more evidence than has been found in prior studies that boys who join gangs are more delinquent before entering the gang than those who do not join. Even with such selective differences, however, we replicate research showing that drug selling, drug use, violent behaviors and vandalism of property increase significantly when a youth joins a gang. The delinquency of peers appears to be one mechanism of socialization. These findings are clearest in youth self-reports, but are also evident in reports from parents and teachers on boys' behavior and delinquency. Once we adjust for time trends, we find that the increase in delinquency is temporary, that delinquency falls to pre-gang levels when boys leave gangs.  相似文献

In 2001, the New York State Permanent Judicial Commission on Justice for Children, chaired by New York State's Chief Judge Judith Kaye, developed the Babies Can't Wait Initiative to maximize the well‐being and permanency prospects of infants in foster care. This court‐based innovation became a path to healthy development for babies in foster care, a bridge to unprecedented collaboration among the New York City Family Court, child welfare system, and service providers and merged knowledge about child development with court and child welfare practice. This article tells the story of the Babies Can't Wait Initiative—its creation, implementation, successes, and lessons.  相似文献
