基于人力资本价值链理论的中国城市国际人才集聚研究

城市国际人才争夺战由来已久并不断升级，但针对中国城市国际人才集聚水平、影响因素和差异化政策供给的研究鲜见。以“国际人才集聚指数-国际人才集聚影响因素-国际人才集聚政策”为研究主线，以中国36个主要城市为研究对象，创新性地通过构建人力资本“投入-过程-产出”价值链理论模型进行实证研究，结果表明：中国城市国际人才集聚指数排名分为3个差异显著的层级。其中，第二和第三层级之间无较大差距，但与由北京、上海组成的第一层级相比大幅落后。中国城市国际人才集聚影响因素分化明显，第一类城市的主要影响因素为全球城市品牌文化；第二类城市为创新型经济发展；第三类为外资传统工商业企业和产业集聚。对应地，中国城市国际人才集聚政策供给围绕外资传统工商业国际人才集聚、高端生产性服务业国际人才集聚、多样性和包容性国际人才文化氛围营造存在三大差异化选择。首次构建人力资本“投入-过程-产出”价值链模型，为从机理上深入探索中国各类城市国际人才集聚模式及提升路径奠定了基础。

WTO框架下保障措施的起源与演化

保障措施是WTO框架下与反倾销、反补贴并列的贸易救济手段，已成为成员方开放条件下市场准入扩大过程中实施的经济安全阀。本文拟从探寻保障措施产生的制度根源出发，考察其在多边贸易体制框架中的变迁轨迹，分析在GATT期间和WTO成立以来的实施特点，并对保障措施制度的历史演进尝试了一种新经济史学的解释。     

Variation in the effects of government spending shocks with methods of financing: Evidence from the U.S.

Using annual data for the United States, the paper investigates the evidence of variation in the fiscal multiplier with the method of financing government spending. The fiscal multiplier varies in the face of positive and negative shocks and across methods of financing. In general, fiscal expansion appears insignificant on aggregate demand and economic activity. In contrast, the evidence presents a number of significant negative multipliers in the face of fiscal contraction. The combined evidence challenges the effectiveness of fiscal policy and supports arguments to restrain fiscal expansion in an effort to stimulate the economy.     

What Price Drug Use? The Contribution of Economics to an Evidence‐Based Drugs Policy

Abstract.  This paper presents a review of the recent economics literature in the area of illicit drug use. Particular attention is paid to the economics of addiction and the rational addiction model, the welfare economics framework for analysing the social costs of drug use, and the attempts that have been made by economists to evaluate recent or proposed policy interventions. A dominant theme in this review is the problem of poor data availability. This is particularly true when it comes to implementing the Rational Addiction model, but it is also apparent in the literature on estimating the costs of illicit drug use to society as a whole. One of the main conclusions of this review is that until recently public policy has not been particularly influenced by research carried out by economists. It is not clear whether this is because economists have had to grapple with inadequate data, and hence their conclusions are couched in uncertainty, or whether it is because drugs researchers have assumed a very limited role for economists in their analysis.     

Developing information policy

The author first considers some of the policy issues that arise in connection with the creation of new information, primarily scientific and technical information. He then discusses specific policy problems stemming from communications and information storage and retrieval systems and their use. A broader integrative view of this field could help develop a national information policy for the future. Such integrative work remains to be done, and suggestions for future studies in this area are given.     

Factors that determine the cost-effectiveness ranking of second-best instruments for environmental regulation

This paper develops a conceptual model to analyze how specific factors affect the compliance costs of three suboptimal policy instruments, when compared to the optimal ambient permit system (APS) benchmark. The model considers a non-uniformly mixed pollutant and explicitly incorporates the following factors: number of polluting sources; size, in terms of emissions, of each process; marginal abatement costs for each process; effluent concentrations; the transfer coefficient that relates emissions to environmental quality at the receptor; and the desired environmental quality target. APS is compared to a suboptimal emission permit system (EPS), and two Command and Control (CAC) policies—equal percentage reduction (PER) and a uniform effluent concentration standard (STD). The results show the importance of the different factors and their interactions in determining each policy instrument’s cost-effectiveness ranking. Surprisingly, EPS performs well within the usual values of these factors and in specific cases STD and PER also perform similarly to APS.      

The use of multi-criteria decision-making methods in the integrated assessment of climate change: implications for IA practitioners

Integrated assessment (IA) considers interactions of physical, biological, and human systems in order to assess long-term consequences of environmental and energy policies such as limits on greenhouse gas emissions, and other strategies to negate climate change. Users of IA face the daunting task of interpreting large amounts of data and uncertainties. Multi-criteria decision-making (MCDM) methods can help users process IA data, understand policy tradeoffs, and learn how their value judgments affect decisions. We held a workshop during which climate change experts tested several MCDM methods for using IA outputs to rank hypothetical policies for abating greenhouse gas emissions. Participants also evaluated several methods for visualizing tradeoffs under both certainty and uncertainty cases. This paper explores potential roles for MCDM in IA identified during the workshop, along with implications for IA design and implementation. We summarize the workshops’ results regarding intertemporal discounting (a type of MCDM weighting judgment), visualization of impacts, how MCDM methods can help users to incorporate their background knowledge, and how MCDM can improve understanding of tradeoffs and the importance of value judgments. A key result is that the interest rates IA experts recommend for discounting future impacts depend strongly on what type of impact is being discounted, as well as upon the exact phrasing of questions used to elicit rates from the experts.
