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

As tensions in the European Monetary System demonstrate, international capital flows can have a decisive influence on countries' economic policies. The external constraint of high international capital mobility led the countries of Western Europe in the 1980s to attempt to stabilize their exchange rates and converge toward low levels of inflation. Yet this process was not uniform: French governments pursued a rigorous anti-inflationary policy of high interest rates and a strengthening currency, while Italian governments had difficulty controlling inflation and maintaining the lira in the European Monetary System. This difference is best explained by comparing political institutions and policymaking processes in the two countries. Particular attention is given to political leaders' access to economic policy tools and their capacity to design and implement long-term goals. 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

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

Explaining differences in productive efficiency: An application to Belgian municipalities 总被引:3,自引:0,他引:3
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
