市场经济的伦理缺陷研究

市场经济的伦理缺陷:首先,表现在市场经济基本理念与传统道德价值与原则的根本冲突;其次,表现在市场经济运行过程对经济原则的片面坚持与对伦理价值的顽固排斥与否定。克服市场经济伦理缺陷的根本办法在于重新审视经济理性的合理性,检讨经济发展的终极意义,使市场经济以及经济理性回复到在伦理规则指引下为人类主体性生存服务的合理轨道上来。     

TRADE LIBERALIZATION AND GROWTH: Evidence from Mexican Cities

Applying the most recent methodology for explaining economic growth differences across countries (Barro, 1997), education, learning by doing, infrastructure, and knowledge spillovers due to specialization have been considered relevant in explaining productivity growth differences in Mexican urban manufacturing (de León, 1999). In this article, I evaluated whether there is a significant change in the relevance of these variables under trade liberalization. In particular, I evaluated the hypothesis that trade liberalization would promote productivity growth in the northern cities as result of the dynamic effect of trade given that these cities are close to the new central market for Mexican manufacturing and the loss of relevance in the previous accumulated growth factors (Livas and Krugman, 1992; Hanson, 1994). In contrast to that hypothesis, I observed that urban manufacturing close to the United States did not show a better performance than the rest of the cities as expected and that accumulated growth factors, such as education, learning by doing, and infrastructure are still relevant in explaining productivity growth across urban manufacturing in Mexico.

Controlling the Urban Fabric: The Complex Game of Distance and Proximity in European Upper‐Middle‐Class Residential Strategies

This article presents an open discussion of the processes of urban secession and gentrification in contemporary European cities, arguing that intergroup social dynamics in urban spaces are generally more complex than either extreme mutual avoidance or the colonization of neighbourhoods by the wealthiest groups. We analyse the residential strategies of urban upper‐middle class managers in various European metropolitan areas through in‐depth semi‐structured interviews to argue that these groups develop complex strategies of proximity and distance in relation to other social groups. The development of these ‘partial exit’ strategies takes place through specific combinations of practices that allow groups to select the dimensions they are willing to share with other social groups, and those in which they prefer a more segregated social environment for themselves and their families. The responses of our interviewees were consistently more nuanced and complex than suggested by a simplistic theory about their drive to withdraw from society, forcing us to develop more sophisticated conceptual frameworks to account for the growing prevalence of multi‐layered identities and spheres of reference and solidarity, specific combinations of elective segregation and local involvement, and more active patterns of mobility combined with local embeddedness.     

我国国际资本流入结构的变化:2001—2008

我国加入世界贸易组织以来，流入我国的国际资本结构发生了较大的变化。从资本数量结构来看，资本总量逐年增加，外商直接投资比重下降，间接投资的比重上升；从资本期限结构来说，短期资本总量超过长期资本总量，中长期债务余额比较稳定，而短期债务增速较快，贸易信贷比重逐年增加；国际资本主要来源地没有大的变化；国际资本流入的行业结构中，虽制造业仍占据较大的比重，但服务业所吸收的外资却快速增长，占比越来越大。     

都市圈快速交通走廊的BRT问题研究

世界众多大城市的发展经验表明：城市的交通模式、交通结构随着城市的快速发展必然需要进行相应的调整，而这种调整可能是主动的，也往往可能是被迫的。近年来，郑州的发展有目共睹，突出的表现在经济增长、居民生活水平提高、城市设施建设和城市空间的拓展上。事实上，郑州已经开始承受城市快速发展给交通带来的阵痛，而许多隐患亦可能在不久的将来暴露出来。同时，人们逐渐意识到单一的以道路设施建设为导向的规划理念已无法适应大都市的进一步发展，而以交通模式指引交通设施建设是城市交通发展的必经之路。

Repeated Dichotomous Choice Formats for Elicitation of Willingness to Pay: Simultaneous Estimation and Anchoring Effect

Repeated dichotomous choice contingent valuation data are generated from responses to a succession of binary questions regarding alternative prices for an environmental good. In this paper we propose a simultaneous equation model that allows for endogeneity and error correlation across the responses at each stage of the bidding process. The model allows us to study the evolution of anchoring effects after the second dichotomous choice question. Estimation involves the Bayesian techniques of Gibbs sampling and data augmentation, and the application focuses on the preservation value of a natural area. The results for a data set involving up to four successive dichotomous choice questions show that restricted multiple-bounded models are rejected by the data with the general model. In addition, willingness to pay tends to stabilize after the second stage in the elicitation process for the general unrestricted model. When taking anchoring effects into consideration, it is revealed that individuals’ responses in the latter stages are influenced by the sequence of bid prices offered in earlier questions. Nevertheless, they do not have a significant effect on welfare estimates.
