Some Empirical Evidence of the Efficacy of Job Matching in Urban Labor Markets

Theory predicts that workers in cities are more likely to engage in job search, ceteris paribus, due to market efficiencies associated with greater job density. However, if job search is more efficient in urban markets, then the quality of a given job match should also tend to be higher in cities, ceteris paribus. Employed workers living in cities might then be expected to search less than their nonurban counterparts. In this latter instance, it is not city residency itself that makes search less likely, but rather the positive correlation between city residency and job match quality. Using data from the National Longitudinal Survey of Youth 1979, this prediction is confirmed: The estimated coefficient on an indicator of urban residency is found to be near zero and statistically insignificant in models of employed search that omit proxies for job match quality. When job match proxies are included in the models, the estimated coefficient on urban residency becomes positive and highly significant. This result suggests that workers are not only more likely to engage in employed search in urban labor markets, but also tend to find more productive job matches in cities over time.

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.

The transition crisis in Bulgaria

In 1996-97, while making its way through a difficult processof economic and political transformations, Bulgaria was hitby a severe economic crisis. This paper seeks to reveal andanalyse the underlying factors and causes of this crisis. Itfocuses on empirical issues but also highlights some basic causalitiesand interrelations between economic variables during the crisisas well as the role of economic policy. The economic turmoilin Bulgaria is addressed from three different perspectives:(1) the historic roots of the crisis; (2) the actual evolutionof the fiscal, banking and currency crises, and (3) the politicaleconomy of the transition in Bulgaria.     

技术效率、资本深化与地区差异——基于随机前沿模型的中国地区收敛分析

本文提出了基于随机前沿生产函数的地区增长差异分析框架,将各地区劳均产出差距分解为劳均资本差异、经济规模差异和全要素生产率差异三个部分。利用改革时期的省级数据,本文发现尽管要素投入仍然是中国经济增长的主要源泉,但全要素生产率是造成地区差异的重要原因,在地区劳均产出差异中的贡献份额不断提高,将成为今后中国地区增长差异的主要决定力量。而且,1990年以来中国地区全要素生产率呈现出绝对发散趋势,严重的技术扩散壁垒加剧了体制转轨过程中的“马太效应”,短期内地区差距不会随经济发展而缩小,政府需要通过适当的政策对地区发展进行调节,尤其要促进地区间技术扩散,使各地区更好地分享技术创新和体制创新的成果。

深化广西—越南跨国物流协调合作的探讨

中国—东盟自由贸易区成立以来,越南一直是广西第一大贸易伙伴和第一大出口市场。通过深化跨国物流协调合作来提高物流效率,进而增强商品核心竞争力,优化双边外贸活动,是广西和越南共同面对的问题。为了解决桂越跨国物流合作中存在的基础设施建设滞后、交通合作机制未能发挥预期作用、物流发展水平低等问题,当务之急,一方面是进一步完善跨国物流硬件设施,另一方面建立桂越跨国物流协同机制,是规范双方物流合作的"软件"工程。桂越跨国物流协同综合系统的建设及其作用的发挥,有待双方在政治、法律、信息技术、服务业等方面的深化合作。
