This article investigates the use of market incentives to encourage household waste recycling by pricing waste-disposal services according to the quantity of waste generated. We use a natural experiment from an upstate New York county to examine how quantity-based pricing of waste disposal affects reported household recycling behavior, when used by itself or in conjunction with curbside pickup of recyclables or mandatory recycling laws. Curbside pickup was found to have the greatest effect on reported recycling behavior, although higher waste-disposal prices might alter these conclusions. Other concerns about quantity-based pricing of solid waste—distributional effects, public acceptance, and adverse incentives—are also examined.  相似文献

Policy implementation has been an infrequently studied process although it has become increasingly evident that the implementation processes of policy development, policy approval, and policy application can shape and delay prospective implementation of legislation. The current study analyzes the implementation of P.L. 99–457 (Part H) the Education for the Handicapped Amendments of 1986. This law provides the states with planning money from the federal government to design a comprehensive interagency, multidisciplinary program of services for children with handicapping conditions and their families. Ratings were taken from key administrators and citizens knowledgeable about the law on state progress in implementing the fourteen requirements of the law and also on proposed influential conditions that might affect that implementation. Additional demographic information was obtained for the fifty states. The factor that seemed to be most influential in a subset of 35 states was the prior presence in the state of systems for interagency planning and development. Neither prior history of early childhood services, available resources, wealth of the state, or geographic region appeared to have a significant influence on policy development. There was some indication that different factors might become influential in the next phase of implementation, policy approval. It appears that progress in state policy development may be linked to the special requirements of the legislation itself and to prior availability of institutional structures that make mandated collaborative efforts more possible.  相似文献

A pervasive theme of the congressional politics literature is that the committee system is fundamental in determining the policy status quo. Such an assertion hinges crucially upon committees controlling their jurisdictions; congressional delegation is undermined if a committee can assert authority over any issue domain at any time. Yet, representatives may possess an incentive to support a policy proposal that would change the status quo, even if it entails disregarding procedures. Indeed, standard conceptualizations of how members of Congress make their voting choices assume that only the benefits and costs associated with a policy matter, and they do not consider institutional factors such as whether a bill emerged from the correct committee.This analysis examines whether representatives will sacrifice policy interests to preserve institutional features of the legislature. The effort in 1987 to curb smoking on airplanes — which became embroiled in a difficult-to-resolve jurisdictional dispute — serves as a vehicle to analyze how sensitive members are to such features. The results demonstrate that a sizable number put aside their [generally moderate] policy preferences and voted against limits on smoking for institutional reasons. These findings have important implications both for specifying the determinants of policy change and for understanding institutional stability.  相似文献
