Regularities in the vertical arrangement of land uses in Sydney's central area

Summary

Previous studies of the vertical arrangement of land uses within the central areas of cities have been few, incomplete and employed crude methods of analysis. The present study employs 24 categories of land uses and analyses their distribution over 50 floor levels in Sydney's central district. To model the data, the gamma distribution is employed, being a flexible curve type. With only trifling exceptions, this distribution represents the data remarkably well. The two parameters of the fitted curves are interpreted as: (a) a measure of the propensity of a use to be accommodated over a wide range of floor levels, and (b) as a measure of resistance to height. The values of the parameters are used to define, using a clustering algorithm, groups of uses having members characterized by the most similar floor level arrangement. The results are of major importance for three reasons: First, the degree of regularity in the way establishments seek locations in the height dimension has not been discovered before. Second, the gamma‐distribution offers utility in modelling vertical location and should be useful in testing aspects of different town planning policies on plot ratios. Third, draconian town planning restrictions imposed on height controls may introduce locational inefficiencies hitherto unsuspected.

实现2500万农民的深层城市化,是中原经济区"三化协调发展"的关键点,这需要解决好土地、就业、社会保障三个方面的问题。中原经济区可以通过先行先试,充分利用支持政策、经济结构调整和自身要素的特点,施行土地的集约利用,积极承接产业转移,鼓励创业等政策,并通过多种渠道筹措所需资金,推动深层城市化的顺利实现。     

The market microstructure of central bank intervention

How quickly do central bank intervention operations impact the foreign exchange market? And, do intra-daily market conditions influence the effectiveness of central bank interventions? This paper uses high-frequency intra-daily data to examine the relationship between the efficacy of intervention operations and the “state of the market” at the moment that the operation is made public. The results indicate that some traders typically know that the Fed is intervening at least 1 h prior to the public release of the information in newswire reports. Also, the evidence suggests that the timing of intervention operations matters—interventions that occur during heavy trading volume, that are closely timed to scheduled macro announcements, and that are coordinated with another central bank are the most likely to have large effects.     

The determinants of service exports from Central and Eastern Europe

The transition economies of Central and Eastern Europe (CEE) have become important exporters of many types of services to Western Europe. We identify the sources of CEE’s advantages over competing exporters, such as India, China and Brazil, using disaggregated data on service exports and a novel estimation technique for the gravity equation. Our results indicate that the importance of geographical distance varies substantially across types of service exports. Geography is important for exports of construction services, but it has a negligible impact on computer‐related services. However, the relative quality of legal institutions influences trade across a broad range of service categories. The results demonstrate that aggregating services that are not homogeneous could conceal important differences in the effects of geographical distance and other variables on the pattern of service trade.

从三次加息看我国央行宏观调控的意图

本文分析了我国央行三次加息的动态、背景厦其政策意图，并进一步指出，央行的这三次加息都是具有方向性的举措，目标是为了进一步巩固宏观调控成果，发挥经济手段在资源配置和宏观调控中的作用。与此同时，三次加息也标志着我国央行释放紧缩信号，开始步入新一轮的宏观调控周期。     

中部崛起政策对地区产业升级的异质性影响与机制分析--基于PSM-DID方法的一项拟自然实验

国家中部崛起政策实施13年来,相关地区的经济发展和产业结构发生不同程度的变化。为进一步引导发展,需对这一政策的实施效果作整体评估和检验。基于1999-2013年我国201个地级市的面板数据,运用PSM-DID方法,从长期影响角度评估中部崛起政策实施效果。结果表明,以地区技术复杂度度量的产业结构得到了显著的提升。在此基础上考察中国式财政分权模式下政府财政行为波动对政策效果的影响,结果显示政府财政支出波动对地区产业升级会起到负面作用。进一步的机制检验表明,吸引外商直接投资、积极性政府财政政策、突破路径依赖是实现政策效果的中介变量;政策着力点主要在高技术水平的产业上;由于地区异质性的存在,部分省份产业升级并未达到预期效果。因此,制定新一轮崛起战略措施时,要因地制宜,充分考虑地区异质性,走内涵式发展道路。
