人民币汇率政策推出时机抉择: 汇率与股指相关性视角

通过构建T-Copula-GARCH模型从人民币汇率与股市指数相关性视角,分析我国深化金融市场改革开放背景下汇率政策推出时机抉择。结果表明：人民币兑美元、日元汇率贬值时,上证指数下降;而人民币兑美元、日元汇率升值时,上证指数上涨。人民币兑欧元汇率、人民币指数升值时,上证指数下降;而人民币兑欧元汇率、人民币指数贬值时,上证指数上涨。人民币兑美元汇率与上证指数相关性波动趋势跟人民币指数与上证指数相关性波动趋势基本相反,人民币兑日元、欧元汇率与上证指数相关性波动趋势跟人民币指数与上证指数相关性波动趋势基本相同。股票市场趋势性上涨后,我国外汇市场和股票市场关联性进一步降低。因此,为弱化外汇市场和股票市场联动风险,人民币兑美元、日元汇率的改革措施应选择在股票市场趋势性上涨阶段推出,尤其是人民币兑美元汇率改革措施的推出;人民币兑欧元汇率的市场化改革对时机窗口要求不高,故在人民币汇率市场化改革中可优先推行人民币兑欧元汇率市场化改革;人民币汇率综合改革措施则可选择在股票市场趋势性上涨阶段推出。     

人民币购买力平价成立吗?——基于人民币兑欧元的多样本协整分析

选取人民币兑非主权国家货币——欧元的名义汇率,中国CPI指数及欧元区调和HICP指数的数据,以欧元正式成为欧元区唯一合法货币的起点2002年7月到2018年12月为样本,依据影响中欧汇率的重要节点事件对样本进行分段与结合,对人民币兑欧元购买力平价(PPP)成立与否进行协整检验。实证结论有:人民币汇率形成制度改革及欧元平稳运行后的(2005年8月—2018年12月)人民币兑欧元购买力平价协整检验成立;非主权国家货币欧元同样适用经典的购买力平价理论;2008年金融危机是影响汇率市场的重要节点事件,但长期不影响人民币兑欧元购买力平价成立;对PPP冲击影响最大的首先是汇率本身,其次依次是欧元区HICP、中国CPI。因此,购买力平价在一定程度上能够解释人民币兑欧元汇率,对中欧经贸往来有一定的指导作用。

经济基本面可以预测人民币汇率吗？北大核心CSSCI

本文选用七个主流基本面模型,利用2005年8月至2016年12月间数据建立美元、日元、英镑、欧元兑人民币汇率的预测模型,检验经济基本面模型对人民币汇率的预测效果。预测结果表明:纳入实际汇率的基本面模型,人民币汇率的预测效果显著提高;在所有预测期限,基本面模型的可预测性均不弱于随机游走模型;基本面模型的短期预测能力较好,中长期预测能力较差;日元和美元兑人民币汇率的预测效果均好于欧元和英镑。

基于swan图像的汇率均衡机制与错位原因分析

<正>一、引言随着中国对外经济开放度的提高,汇率问题一直困扰着我国的经济增长,在内外均衡的历次冲突中都会发现汇率失衡的影子。1994-1995年的内外冲突是汇率制度改革的结果,人民币汇率由5.8元人民币兑1美元一次性贬值到8.7元人民币兑1美元,刺激了外国资本的流入和贸易顺差,持续的双顺差又加     

当前人民币汇率争议的文献综述及改革的趋势

随着经济步入＂后危机时代＂,国际贸易保护主义风险加剧,人民币汇率再次成为争论的焦点,2010年5月24日至25日在北京举办的一年一度的中美战略与经济对话也将此作为四项议题之一进行讨论。如何判断人民币当前的汇率水平是否合适、人民币汇率变动对中美之间的贸易会产生何种影响、人民币汇率改革将走向何方等成为理解这一热点问题的关键。本文围绕人民币汇率是否低估、人民币汇率是否可以解决贸易问题、以及人民币汇率形成机制改革等议题,对当前理论界和学术界的各种观点进行了全面梳理,试图为深刻理解人民币汇率制度未来的改革方向研究提供参考。     

Debt and Taxes and Uncertainty

With a graduated personal tax schedule, Miller showed that there could be an equilibrium debt supply for the corporate sector as a whole. In the presence of uncertainty there is also a unique debt/equity ratio for each individual firm, and this ratio is related to the firm's operational risk characteristics. However, if firms merge and spin off in response to tax incentives, the identity of firms is ambiguous and only the corporate sector is a meaningful construct. These arguments are developed in both discrete and continuous models that employ extensions of the arbitrage-free pricing theory.     

教育与资本怎样的前景怎样的现实

来自政府的声音: "动员各种社会资源,发展教育" 此次论坛上财政部长助理张少春的发言是最受关注的发言之一.他的演讲传达出的信息有这样几方面:第一,谈到现实,他认为全社会对教育的巨大需求与我国公共投入不足已成为我国教育事业发展的突出矛盾.近年来,以公共部门投入为主,多渠道筹措教育经费的教育投入机制成为解决这一问题的重要途径,也使得公共部门与私营部门在教育领域的合作日益密切.第二,谈到前景,他认为,1.中国经济持续、快速的增长对高技能人才产生巨大的需求,这为私营部门的参与提供了广阔空间.2.随着公共财政职能的不断完善,财政资金将在各项教育事业中重新进行分配,进一步优化财政支出结构,提高资金的使用效率.在"十一五"期间,我国将把公共支出的重点转移到农村.我们将逐步把全体农村适龄儿童的义务教育全部纳入公共财政体制.     

Director gender and mergers and acquisitions

Does director gender influence CEO empire building? Does it affect the bid premium paid for target firms? Less overconfident female directors less overestimate merger gains. As a result, firms with female directors are less likely to make acquisitions and if they do, pay lower bid premia. Using acquisition bids by S&P 1500 companies during 1997–2009 we find that each additional female director is associated with 7.6% fewer bids, and each additional female director on a bidder board reduces the bid premium paid by 15.4%. Our findings support the notion that female directors help create shareholder value through their influence on acquisition decisions. We also discuss other possible interpretations of our findings.     

Political corruption and mergers and acquisitions

This research examines the relation between political corruption and mergers and acquisitions (M&As). We find that local corruption increases firm acquisitiveness but decreases firm targetiveness. The levels of corruption in acquirer areas relate positively to the bid premiums and negatively to the likelihood of deal completion. Corruption motivates acquiring firms to use excess cash for payment, which mitigates the negative effect of corruption on acquirer shareholder value. The evidence indicates that acquisitions help acquiring firms convert cash into hard-to-extract assets and relocate assets from the high to low corruption areas, thereby shielding their liquid assets from expropriation by local officials.     

East and west and north and south : A preliminary model

The Brandt report and other proposals for a new North-South world order continue to be the focus of lively debate, yet it is often argued that little concrete has emerged from their recommendations. A major reason for this, the author argues, is that the East-West conflict component is not sufficiently taken into consideration-East-West tensions are a severe constraint on and a determining factor of North-South relations. Using influence diagrams, the author develops a flexible framework for discussion and assessment of N/S-E/W relations.     

Trust and cross-border mergers and acquisitions

A number of studies suggest that social trust matters for investment. Using different measures of trust from World Values Survey, we show that countries where people display higher levels of trust engage in more cross-border M&A activities. When they do, these acquirers pay lower premiums. To the extent that these acquirers also tend to engage in larger acquisitions as well, our findings suggest that a larger selection pool of potential targets and higher value targets enable these acquirers to negotiate for lower premiums. We do not find evidence of the significant effect for target country trust levels. Hence, trust may benefit those acquiring firms in cross-border transactions.     

Tournament-based incentives and mergers and acquisitions

This research examines the relation between tournament-based incentives, which are proxied by the difference between a firm's CEO pay and the median pay of the senior managers, and mergers and acquisitions (M&As). We find that tournament-based incentives are positively related to firm acquisitiveness and acquiring firms' stock and operating performance. Further analysis indicates that positive acquisition performance increases the likelihood of the CEO being promoted from inside the acquiring firm. Our evidence is consistent with the view that tournament-based incentives motivate acquiring firms' managers to make greater efforts and take more risk that result in superior acquisition performance.     

Corporate Innovations and Mergers and Acquisitions

Using a large and unique patent‐merger data set over the period 1984 to 2006, we show that companies with large patent portfolios and low R&D expenses are acquirers, while companies with high R&D expenses and slow growth in patent output are targets. Further, technological overlap between firm pairs has a positive effect on transaction incidence, and this effect is reduced for firm pairs that overlap in product markets. We also show that acquirers with prior technological linkage to their target firms produce more patents afterwards. We conclude that synergies obtained from combining innovation capabilities are important drivers of acquisitions.
