工程建设施工阶段的质量控制

工程施工过程中的质量控制是工程质量控制工作中的重点,是保证工程质量的关键。工程质量的好坏,不仅与设计选型有关,而且与施工质量有关。因此,要对工程建设各个施工阶段的质量控制做到层层把关,环环紧扣,争创优质工程。     

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.

The Costs of Increasing Transparency

In their seminal paper, Morris and Shin (Amer Econ Rev 92(5): 1521–1534, 2002a) argued that increasing the precision of public information is not always beneficial to social welfare. Svensson (Amer Econ Rev 96: 448–451, 2006) however has disputed this by saying that although feasible, the conditions for which this was true, were not all that likely. In that respect, therefore, increasing ‘transparency’ remains most of the times beneficial to social welfare. In this paper, we extend the Morris and Shin attempt by setting it up as an explicit interactive game between the Central Bank, the objectives of which we model explicitly, and the private sector. We show that in the absence of costs, both players benefit from transparency in the manner described previously in the literature, and point the differences in their gains. Following that, we then introduce the fact that increasing transparency comes at some costs and show how both players face incentives to free ride on each other as a result. The presence of costs thus alters the way in which greater transparency is attained.

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。
