Trade‐led growth hypothesis in Cuban commercial regimes since 19601,2

This study examines the impact of trade on Cuban growth during different commercial policy regimes spanning the period from 1960 up to 2004, encompassing two essential economic structural transformations: the Cuban revolution and the fall of the Berlin Wall. For this purpose, the Granger causality is used by means of the modified Wald test for augmented‐level vector autoregressive model with integrated and cointegrated processes introduced by Toda and Yamamoto (1995) and Dolado and Lutekepohl (1996) . We show an import‐led growth hypothesis during the Soviet‐oriented pattern that is rejected after 1990, when exports are not only responsive to growth expansion but also to imports’ behaviour.

Abstract

The great world economic and globalisation boom of the pre-First World War era was accompanied by great inequality in the distribution of income and wealth particularly during industrialisation, with the new world European settler economies being no exception. Canadian wealth inequality over the period 1870–1930 was also substantial and is examined using probated estates from the Eastern Judicial District of the province of Manitoba and Wentworth County, Ontario. However, wealth inequality is found to be less pronounced in frontier Manitoba relative to Ontario with higher and more dispersed rates of land ownership in the West as well as lower wealth levels and greater farm employment, as the key factors in this difference. This suggests that the farm economy of pre-First World War Canada was associated with greater equality of wealth. One of the inevitable effects of Canadian industrialisation and economic development was a rise in wealth inequality but the process of western settlement and associated free grants helped mitigate it. By extension, global economic inequality might also have been mitigated during this period by the presence of agricultural frontiers with subsidised land grants.     

Underwriter Lock-up Releases, Initial Public Offerings and After-market Performance

The lock‐up agreement between an underwriter and an issuing firm's principals prohibits sale of securities for a period of time following the offering date. Investment banks must support the stock following an offering. The lock‐up assures investors that the restricted shares will not enter the market, at least for a period of time. Negative abnormal returns prior to the lock‐up release show that unrestricted investors liquidate positions prior to the scheduled lock‐up release. Negative abnormal returns are more robust for firms that are not influenced by SEC Rule 144 than for firms that are.     

中国应对美国启动IPR争端解决机制的对策

知识产权（IPR）保护问题已经成为中国贸易关系中的一个非常严重的问题。虽然中国的知识产权保护法律体系已经相当完善，但并不排除中国知识产权立法、执法和《与贸易有关的知识产权协定》项下中国承担的义务不相一致的情形。如何使中国的知识产权保护立法和执法符合中国“入世”承诺，是中国面临的紧迫问题。否则，美国将会毫不犹豫地启动WTO争端解决机制。     

“美丽乡村”视角下河南省乡村聚落空间优化研究

[目的]在国家高度重视建设"美丽乡村"的背景下,加强乡村聚落空间分布格局及优化研究,对指导新农村建设,实现农村居住地的集约化管理,改善农村现有生态环境,促进城乡协调发展具有重要意义。[方法]文章运用平均最邻近比率、平均分布密度和乡村聚落平均人数描述河南省乡村聚落分布特征,并采用Arcgis10. 2绘制乡村聚落平均分布密度图,从县域和市域尺度分析了乡村聚落的空间分布特征,指明该省乡村聚落发展中存在的问题,并提出了合理性的优化建议。[结果](1)河南省乡村聚落整体呈集聚分布,从空间位置来看,都集中在东北部地区。(2)乡村聚落县域分布密度差距较大,主要表现在中东部地区和东北部地区平均分布密度较大,呈沿交通要道周围分布,东南和西北地区平均分布密度较低。(3)各市级行政单位乡村聚落分布区域差异比较明显,洛阳市、驻马店市、南阳市、信阳市和三门峡市的聚落密度较小,均低于全省乡村聚落平均密度。漯河市、三门峡市、濮阳市和济源市的行政村均人数不足800人。[结论]针对小规模聚落的零散分布和偏远贫困区域乡村聚落的边缘化等问题,今后该省可重点建设中心村,以城带乡发展城边村,同时加大对边缘聚落的改造,结合当地文化优势,发展乡村旅游,提高当地居民进行自我建设的积极性。     

河北保定农户居住空间行为选择的动力机制研究

农户对居住空间的行为选择是直接影响乡村空间秩序的重要因素,只有充分认识并准确把握其空间行为选择的现状及存在问题,才能从行为主体空间行为选择上进一步探寻合理引导其空间行为演变的发展道路。为了探讨当前新型城镇化背景下农户居住空间行为的演变规律,研究基于微观视角对保定市不同地区的农户进行了居住空间行为的问卷调查,并对结果进行了统计分析和结构方程模型的构建与检验。实证结果表明:(1)调查区域大部分农户对当前居住空间的满意程度为一般;(2)在农户居住空间满意度方面,配套环境驱动占主要地位,其路径系数高于住房条件驱动;(3)在配套环境驱动方面,经济活动交易便利是最主要因素;在经济生产条件驱动方面,耕种便利因子的影响程度高于灌溉条件。在住房条件驱动方面,各具体测度变量根据影响的主次程度排序依次为:建筑面积、宅基地面积、房屋结构、排水便利、出路与交通。建议保定市从配套设施建设、循序渐进的规范化引导、创新制度体系建设等方面合理引导农户居住空间的行为演变。
