外汇监管套利研究：基于外汇差额缺口视角

2008年全球金融危机后，学术界一致认为监管套利是导致危机的重要原因。当前，外汇管理处于渐进性改革中，放松外汇管制和人民币国际化步伐加快，外汇监管套利迅速发展。本文以进出口、收付汇、结售汇差额缺口为度量指标，对差额缺口的构成、影响因素进行分析，对外汇监管套利行为进行研究，在此基础上得出研究结论。     

“Moving” land across borders: spatial shifts in land demand and immiserizing effects

The rush for land acquisition has attracted considerable attention from the scientific community, although actual research on the topic remains thin. This paper attempts to break new ground by studying the potential effects of land deals in the context of a small open economy subject to exogenous shocks. In particular, it makes three main arguments: first, an increase in world prices of the agro-business sector causes skewed effects in the subsistence sector; second, an attractive premium offered by hosts to lure investors may have immiserizing effects; and third, technological efforts will have favorable effects if host countries adopt policies to revitalize agriculture.     

居民收入差距的财政调节:绩效测度与因素分析——基于辽宁城镇居民视角的分析

采用统计年鉴权威数据,运用统计与计量研究方法,对辽宁城镇居民收入差距的财政管理绩效进行测度与分析。研究表明2002年以来辽宁城镇居民收入差距未能得到有效缓解和控制,财政管理手段对城镇居民收入差距调节低效,甚至存在负效应;辽宁城镇居民收入差距的静态来源和动态趋势存在各自特征,其中财产性收入的影响与调控值得关注,经营性收入亟待重视。最后依据测度结论及辽宁经济社会发展实际,提出改善辽宁居民收入结构的政策取向和对策建议。     

Regional Energy Efficiency of China’s Commercial Sector: An Emerging Energy Consumer

This article applies a parametric metafrontier method and the Malmquist index to analyze the energy efficiency and its dynamic performance in China’s commercial sector from 1995 to 2013. The results indicate that the energy efficiency in China’s commercial sector is generally low, and there are significant regional differences and enormous energy-saving potentials. Relative to metafrontier, commercial sectors in eastern China have relatively higher energy efficiency; while those in central and western China have relatively low energy efficiency. Besides, the dynamic energy efficiency performance in China’s commercial sector has improved over the period. The technology improvement is a major driving factor to improve the energy efficiency in the commercial sectors of all the three regions.     

Output Gap Estimation and Monetary Policy in China

Using the Bayesian multivariate Beveridge-Nelson decomposition method, this paper estimates China's output gap based on a multivariate dynamic model featuring distinct interactions among real output, inflation, money, and the exchange rate in China during the period 1980-2010. The authors compare the statistical nature and potential forecasting effects of the resulting multivariate gap measure on monetary policy with those of the output gap measures based on univariate models. The empirical results show that only the measure based on the multivariate system significantly predicts monetary policy, which indicates that the output gap estimated by the multivariate system contains more information than the traditional measures for macroeconomic policy adjustments do.     

中国的房价问题：现状、问题、成因及解决方向——现代社会是如何偏离“住者有其屋”这一理想的

当前国内房价的居高不下源于需求和供给两方面的因素:需求方面主要在于投机性需求和投资性需求,其中,投机性需求源于当前房地产市场化过程中的配套制度不健全,而投资性需求则根本上与收入差距的拉大密切相关;而供给方面则主要源于高地价和高利润的冲击,其中,高地价源于不合理的财政税收制度,高利润则根本上与不合理的土地资源占有关系有关。显然,要解决住房问题,也就要从上述四个方面着手。但不幸的是,现代主流经济学却基于伦理自然主义将这种现状合理化了,从而使得住者有其屋这一理想离现代社会越来越远。     

A Meta-analysis of the Gender Gap in Performance in Collegiate Economics Courses

The conventional wisdom has been that men outperform otherwise equivalent women in collegiate economics courses. Recent work in science, technology, engineering, and mathematics (STEM) fields documenting gains by women suggests that it is time to reevaluate the gender performance gap in economics. Surveying 68 studies containing 235 distinct regressions published since 1980, we find that 68.4% of regressions report men outperform women, though this is only statistically significant in 30.7% of regressions. Although the literature points to numerous reasons for this gap, our focus is on the effects of study design and the impact of broad socio-cultural changes over time. Using meta-regression analysis, we find that the likelihood of observing a statistically significant gap has declined noticeably, by almost 3% annually. Although the drop may not be as large as in some STEM fields, the result is highly robust to the specification of the time trend and the model.
