国际铸币税收支对我国经济影响的实证分析

人民币国际化使我国获得国际铸币税收入,由于国际收支顺差导致的外汇储备增加又使我国支出国际铸币税,因此,国际铸币税也有一个收支问题.本文在计算我国1996年-2011年国际铸币税收支情况的基础上,运用相关性和回归方法实证分析了我国的国际铸币税收支对我国经济的影响.最后得出：我国的国际铸币税收支对我国的物价水平、利率水平、汇率水平、财政赤字、净出口没有影响,对我国的GDP、货币供给和外汇储备有影响.     

The Economic Effects of the Soccer World Cup 2006 in Germany with Regard to Different Financing

This paper presents some results using the sport-economic simulation model SPORT. This model is based on a sport-specific input-output table for the year 1993, which has been integrated into the German INFORGE model. The performance of this model founded on the INFORUM philosophy. The results illustrate the importance of modelling sport-economic activities in deep detail, especially the integration of the system of national accounts. In addition, the results also show that it is possible to calculate the macroeconomic effects of the soccer World Cup, which may perhaps be hosted by Germany in 2006, with regard to the different financing of necessary extensions of public sports infrasfructure. Under favourable conditions-independent of the type of financing of these necessary investments-the staging of the soccer World Cup positively influences income and employment. Such calculations allow the decision-maker to estimate the opportunity costs of their decisions and can be the basis for an extended cost-benefit analysis.     

Data Envelopment Analysis of different climate policy scenarios

Recent developments in the political, scientific and economic debate on climate change suggest that it is of critical importance to develop new approaches able to compare policy scenarios for their environmental effectiveness, their distributive effects, their enforceability, their costs and many other dimensions. This paper discusses a quantitative methodology to assess the relative performance of different climate policy scenarios when accounting for their long-term economic, social and environmental impacts. The proposed procedure is based on Data Envelopment Analysis, here employed in evaluating the relative efficiency of eleven global climate policy scenarios. The methodology provides a promising comparison framework; it can be seen as a way of setting some basic guidelines to frame further debates and negotiations and can be flexibly adopted and modified by decision makers to obtain relevant information for policy design. Three major findings emerge from this analysis: (i) stringent climate policies can outperform less ambitious proposals if all sustainability dimensions are taken into account; (ii) a carefully chosen burden-sharing rule is able to bring together climate stabilisation and equity considerations; and (iii) the most inefficient strategy results from the failure to negotiate a post-2012 global climate agreement.

Low carbon transport strategy in Europe: A critical review

ABSTRACT

The purposes of this article are to depict ongoing trends regarding the transport system in Europe, to introduce readers to the challenges that Europe (and the rest of the world) will face in the future, to show which strategies Europe plans to deploy to mitigate the negative impacts the transport system imposes on the overall system, and finally to discuss the potential of these suggested strategies to contribute to the objectives of the European Union in the long run.

基于引入理想决策单元DEA的公租房配租方法研究

摇号是目前重庆公租房分配的唯一形式,由于不能区分谁更迫切地需要公租房的问题,不能更好地解决分配公平的问题,本文在建立申请人状况的评价指标系统基础上,采用引入理想决策单元的数据包络分析模型,考虑申请人的困难状况对申请人进行评价和排序,以比摇号更公平的方式分配公租房,这在目前公租房数量较少的情况下有更现实的公平意义.     

DEA APPLIED TO A GAUTENG SAMPLE OF PUBLIC HOSPITALS1

The research presented in this paper provides an analysis of the delivery of a few health care services by the public sector in Gauteng, South Africa. The data for the study was especially difficult to collect, suggesting the need for hospital level data information systems, as well as staff who are trained to analyze the information collected. The empirical results from the analysis suggest that services provided by small‐scale medical facilities waste fewer resources, while medical centres offering more technical services, such as surgeries, also appear to deliver medical services more efficiently.
