Comparing Interpersonal Comparisons in Utility Theory and Happiness Research

Social scientists are reluctant to make explicit interpersonal comparisons of well-being. However, implicit comparisons are made on a surprisingly regular basis. These comparisons are based on the wealth and the Kaldor–Hicks concept in utility theory and on self-reported well-being in happiness research. Taking a utilitarian stance, this paper tests the ethical foundations of both principles. While self-reported well-being serves as an acceptable proxy for utilitarian decision-making, the Kaldor–Hicks concept does not appear so. Implications for evaluating policies are outlined.

Price competition in a differentiated products duopoly under network effects

We examine price competition under product-specific network effects, in a duopoly where the products are differentiated both horizontally and vertically. We emphasize the role of consumers’ expectations formation. When expectations are not influenced by prices, the market may be shared but shares must be equal unless product qualities differ or one firm, possibly even the low-quality one, may capture the entire market. When expectations are influenced by prices, which would be the case when there is commitment, competition becomes more intense and the high-quality firm tends to capture a larger market share. Under strong network effects there is a continuum of equilibria and the higher the prices, the smaller the difference between those prices can be. Requiring continuity of expectations, however, delivers a unique equilibrium where one firm captures the entire market.     

“省直管县”改革会损害地级市的利益吗?

我国多个地区正在探索"省直管县"体制改革,目前的最大顾虑是改革是否会损害地级市的利益?本文利用1999—2008年我国地级市数据,通过系统GMM估计对此进行了实证研究。结果发现:"强县扩权"提高了城市财政收入,抑制了城市财政支出增长;财政"省直管县"的作用则恰好相反。"强县扩权"促进了城市经济增长,但不利于城市第三产业的发展;财政"省直管县"虽然降低了城市经济增长速度,却提高了第三产业比重。两项改革措施都抑制了城市规模的扩大,但有利于改善城市的环境质量。因此,我们不能笼统地断定"省直管县"改革一定会有损地级市的利益、阻碍城市化的进程,应深入地研究各项改革措施的利弊得失,做到综合运用、扬长避短。     

宏观统计数据质量规范研究

根据国内外宏观统计数据质量规范演变的历程,在界定宏观统计数据质量新内涵的基础上,依据国际货币基金组织评价数据质量的规范,本文对我国宏观数据质量的规范进行了实证研究。我国宏观数据质量在金融统计数据、社会人口统计数据上与国际货币基金组织制定的数据公布通用系统(GDDS)一致,而财政统计数据与对外经济数据与GDDS尚存在差距;我国数据公布系统在金融统计和人口统计上与GDDS一致,在对外统计与财政统计上与GDDS存在一定差异。

Measuring quality performance of cadastral survey and deeds registration work processes

When land parcel boundaries are surveyed for purposes of registration in most southern African countries, the cadastral survey records and diagrams prepared have to be examined and approved by the Surveyor General first before they can be registered in the Deeds Registries. For such records to be approved, their quality must conform to requirements stipulated in relevant acts and regulations. Where regulatory requirements are not met, the records are rejected and returned for corrections and resubmission. From a cross-organizational context, poor quality documents lodged upstream have the effect of congesting examination processes downstream as records are rejected and returned backwards due to quality failure. The paper proposes a quality performance measurement model to analyze quality performance in land administration work processes. The developed model is tested on 2 survey examination and approval sites and 3 deeds registration sites in Namibia, Zimbabwe and South Africa. Based on below expected quality results obtained at one of the sites, a root cause analysis was conducted to establish recurring and underlying causal factors upon which quality improvement strategies can be built on.

中关村科技园区创新质量的时空集聚效应研究

创新作为中关村科技园区的基本属性,创新质量决定了中关村科技园区发展质量。科技园区促进区域产业集聚,集聚显著影响科技园区创新,但缺乏对“一区多园”创新质量的综合集聚效应研究。由此,建立中关村科技园区创新质量指标体系,在分析中关村科技园区3种集聚模式的基础上,建立集聚模式对创新质量影响的动态空间面板模型;以2006—2017年中关村科技园区等相关数据为基础,研究不同集聚模式与创新质量的时空效应并对其进行分解分析。结果表明,中关村科技园区创新质量呈现显著时间循环效应和空间溢出效应,各园区创新质量空间集聚存在高-高、低-低等模式并随着时间推移发生跃迁。所有园区受到正向显著的专业化集聚影响,大兴-亦庄园受到负向显著的多样化集聚影响,而房山园、密云园和延庆园受到的多样化集聚影响不显著,海淀园、朝阳园、大兴-亦庄园、东城园、西城园、通州园、门头沟园和顺义园受到市场竞争集聚效应的影响。     

区际产业转移关联溢出与产业高质量发展——对电子设备制造业的实证检验

基于我国区际产业转移大背景,使用1999-2016内地年30个省市、27个二位数工业行业数据定量测度区际产业转移,选择产业关联较强的电子设备制造业为研究对象,使用投入产出法识别关联产业、测算其关联产业溢出,利用2004—2016年内地28个省市面板数据构建模型对关联产业溢出效应与电子设备制造业转移的关系、产业转移中的关联产业溢出与电子设备制造业高质量发展的关系分别进行了实证检验。研究发现：①2014年中国工业空间基尼系数出现拐点,总体工业由之前的分散转移转为新的集中转移,而电子设备制造业仍处在向中部地区和西南地区集聚的分散转移中;②电子设备制造业转移中的产业关联溢出效应确实存在,且促进了电子设备制造业生产效率的提高和产业高质量发展;③产业转移中第三产业关联溢出效应对电子设备制造业分散转移的作用高于工业,但工业的关联溢出对电子设备制造业生产效率提升的作用明显高于第三产业。
