2008年国际金融危机后,我国M2供给增幅远高于CPI上涨幅度,这一现象被学界称为“货币失踪之谜”。本文构建了一个两部门新凯恩斯货币模型来研究这一问题。当外部需求下降后,央行降低利率以提振经济,房地产部门和非房地产部门同时扩张。由于住房属于耐用消费品,具有一定的金融属性,其需求对利率变化更敏感。利率下降后,住房需求相对普通消费品需求上升更多。因为存在土地市场分割,商住用地供给弹性较小,住房需求上升导致商住用地价格上升较多,地价上涨提升了房地产企业的抵押融资能力,房地产部门进一步扩张。普通消费品需求对利率反应小,需求较弱导致工业用地价格上升幅度较小,非房地产部门抵押融资能力小幅提升。因此,非房地产部门产出和CPI只温和扩张。Ramsey最优货币政策模拟表明,只有实现了房地产部门与非房地产部门均衡发展,才能实现社会福利最大化。  相似文献

文章通过对近年来世界TBT和SPS通报的趋势分析、结构分析和对主要国家的聚类分析,指出食品安全与环境保护是当前和今后一个时期世界技术性贸易措施通报的重点,发达国家已基本建成安全与环境保护体系,食品安全保护重心前移;技术与经济发展水平和本国发展与保护重点是通报数量与结构的主要影响因素,并通过技术标准国际扩散的路径分析,提出了技术性贸易措施国际扩散模型,为重点跟踪分析和应对技术性贸易措施提出了依据.  相似文献

基于新异质性贸易理论,分析贸易自由化与异质性特征对企业资源配置和创新效应的影响.结果表明:贸易自由化可通过技术溢出效应、市场效应影响企业技术创新,提升我国工业企业的创新能力.同时考虑企业内外部异质性,发现贸易自由化与不同属性的企业的技术创新能力有密切关系,东部地区大型国有企业存在显著技术溢出创新提升.鉴于此,应充分结合贸易自由化对异质性企业的影响效应,提高企业的生产率和降低进入壁垒,优化市场结构.  相似文献

While the welfare effect of foreign aid has been extensively analyzed, the impact on the distribution of income has received less attention. At the same time, there has been recent work on tourism where it is complementary to aid in improving welfare. By combining these two strands, this paper concentrates on wage inequality in developing countries. We find that an increase in aid in the form of tied aid can lower the relative price of nontraded goods. The rent extracted from tourists declines, reducing welfare of domestic residents. In addition, the fall in the nontradable price can widen the wage inequality between skilled and unskilled workers. Thus, increased foreign aid may have detrimental effects on national welfare and the distribution of income. Rising wage inequality is confirmed by numerical simulations.  相似文献

长记忆性研究一直是金融实证研究的一个热点,但过去多数研究主要集中于资本市场。汇率收益率的长记忆性将影响外汇市场的有效性,汇率收益波动率的长记忆性则可能对汇率风险及汇率未来变化产生作用。基于此,本文选择人民币兑美元汇率、欧元兑美元汇率作为研究对象,运用经典重标极差分析法、重标方差分析法及小波方差分析法分别考察它们的收益率和收益波动率序列的长记忆性。研究结果表明:人民币汇率收益率存在长记忆性,而欧元汇率收益率不存在长记忆性;两种汇率收益波动率都存在显著的长记忆性特征,但人民币汇率收益波动率的非周期循环天数长于欧元汇率收益波动率。结论说明了欧元汇率发展的成熟以及人民币汇率形成机制的相对低效,并为追踪汇市行为特征及制定外汇政策提供了新的视角。  相似文献

When William Bratton was appointed police commissioner of New York City in 1994, turf wars over jurisdiction and funding were rife and crime was out of control. Yet in less than two years, and without an increase in his budget, Bratton turned New York into the safest large city in the nation. And the NYPD was only the latest of five law-enforcement agencies Bratton had turned around. In each case, he succeeded in record time despite limited resources, a demotivated staff, opposition from powerful vested interests, and an organization wedded to the status quo. Bratton's turnarounds demonstrate what the authors call tipping point leadership. The theory of tipping points hinges on the insight that in any organization, fundamental changes can occur quickly when the beliefs and energies of a critical mass of people create an epidemic movement toward an idea. Bratton begins by overcoming the cognitive hurdles that block organizations from recognizing the need for change. He does this by putting managers face-to-face with operational problems. Next, he manages around limitations on funds, staff, or equipment by concentrating resources on the areas that are most in need of change and that have the biggest payoffs. He meanwhile solves the motivation problem by singling out key influencers--people with disproportionate power due to their connections or persuasive abilities. Finally, he closes off resistance from powerful opponents. Not every CEO has the personality to be a Bill Bratton, but his successes are due to much more than his personality. He relies on a remarkably consistent method that any manager looking to turn around an organization can use to overcome the forces of inertia and reach the tipping point.  相似文献

We test and cannot reject the hypothesis that retail pricing of natural gas is transparent for commercial and residential customers served by regulated local distribution companies in the United States. The periods of adjustment to a wholesale price change are 1.54 months for the commercial price and 1.69 months for the residential price. These findings support the view that regulated local distribution companies quickly adjust retail prices to fully capture any change in the wholesale natural gas price.

投机、操纵与国际油价   总被引:1,自引:1,他引:1  
投机是否推高了原油价格是国际上广泛争议的问题.基于对争论双方论据和论证的考察,认为原油期货市场资金规模的急速扩张是投机推高油价论的重要论据,但是,正方使用的分析方法适用于股票市场,不适用于期货市场;反方的研究方法虽然是科学的,但是由于存在监管漏洞,其论据的可靠性存在问题.通过深入分析期贷市场结构、期货交易特点以及原油期货交易监管等问题,指出期货市场的新型参与者即商品指数基金往往通过与大型投资银行的互换协议进入期货市场,进而从动机和可操作性分析,得出了华尔街大投行和美英大型石油公司可能操纵油价的假说,澄清了先前意见相左的权方在讨论中的一些模糊之处,给后面的研究提供了新的思考路径.同时指出,这种对油价的操纵即使存在,也不能决定油价的长期趋势和水平.  相似文献

This study aims to empirically examine the changes in production efficiencies of China's township and village enterprises (TVEs) between 1988 and 1993 with particular reference to the spatial disparity of these changes. The stochastic frontier production model, which incorporates inefficiency effects, is adopted in the study. Findings of this study indicate that the technical production efficiency of China's TVEs had, on average, declined between the six years under study. Furthermore, the findings also suggest that the industrial performance of China's TVEs (in terms of production efficiency), like the development.  相似文献

This study explores the consistency between human resource (HR) managers' roles and HR performance indicators. In particular it considers the moderating effects of interpersonal trust on the relationship between HR managers' roles and HR performance indicators. We selected 116 HR managers from the top 500 manufacturing companies in Taiwan as our sample, and hierarchical regression analysis was conducted to test our hypotheses. The results showed that the HR managers' roles were consistent with HR performance indicators. Also, a high level of affective trust weakened the positive relationship between HR manager roles and HR performance indicators. Thus we suggested that Chinese companies should design HR performance indicators according to the roles HR managers play. Additionally, when HR managers are playing the role of a strategic partner or change agent, top executives should avoid high affective trust with HR managers.  相似文献
