Among the best-known theorems of fiscal federalism is the presumed allocative and distributive equivalence between a lump-sum grant to a collectivity and a set of lump sum grants to the members of a collectivity. Interestingly, the simple elegance of the theorem is at odds with observed behavior. Grants to governments produce greater public spending than does tax reduction. Explanations of this "flypaper effect" range from misspecified econometric modeling to presumed behavior based on fiscal illusion. In this paper we show that theoretical equivalence exists in a model that recognizes only one tax share, the citizen voter's local tax share. When the model is expanded to include voters' federal tax shares as well as local taxes, non-equivalence and the flypaper effect become the rule, not the exception.  相似文献

Smoking bans are gaining widespread support in the United States and other countries. While supporters argue that bans are necessary to resolve market failures associated with negative externalities, the Coase Theorem predicts that, under various conditions, private markets internalize negative externalities. We examine the smoking issue within the framework of the Coase Theorem and hypothesize that smoking bans misallocate air space resources shared by smokers and nonsmokers. Because smoking bans shift ownership of scarce resources, they are also hypothesized to transfer income from one party (smokers) to another party (nonsmokers). Supporting evidence for these hypotheses is provided by an examination of a comprehensive smoking ban imposed in San Luis Obispo, CA.  相似文献

This paper analyzes an exchange rate policy game between a central bank and rational speculators under symmetric information. The central bank tries to counteract shocks to the exchange rate by means of sterilized intervention working through the expectations channel. Private speculators resist being fooled. They anticipate the interventions. An “intervention bias” results with an inefficiently high equilibrium volume of intervention which does not reduce the impact of shocks to the exchange rate. The model implies that the more independent the central bank the smaller and the more consistent the intervention efforts. An empirical illustration lends some support to the model.  相似文献

Concerns about U.S. competitiveness have increasingly focused the attention of policymakers on the workforce and mechanisms that could be used to enhance both the quality and quantity of human capital in the workplace. This article focuses on basic skills education of hourly workers, precisely the type of human capital which is likely to be most underprovided by the private market. Five questions are addressed: First, what is the nature of workplace education programs? Second, why do some firms provide workplace education programs while others do not? Third, what, if any, characteristics distinguish those firms that provide workplace education programs from seemingly comparable firms that do not? Fourth, what, if any, evidence can be found identifying the effects of these programs on the firms that sponsor them? Fifth, what policies appear most likely to stimulate additional workplace education?  相似文献

The purpose of this paper is to measure and explain variations in productive efficiency of municipal governments in Belgium. Technical efficiency is evaluated using a non-parametric method based on the Free Disposal Hull (FDH) reference technology. We first calculate input, output, and graph Farrell efficiency measures for a cross-section of all 589 Belgian municipalities. In a second stage of the analysis we explain the calculated differences in efficiency in terms of variables related to the structural characteristics of municipalities and to the institutional environment.  相似文献
