人民币汇率改革的回顾与前瞻

汇率改革的重大意义是使人民币成功退出固定汇率制,并且形成了一整套向市场化转轨的理论、制度和政策框架。汇率改革的进程将进一步实现汇率市场化,逐步加大汇率波动的弹性。随着汇率改革的深化,必须努力完成经济增长路径的转换,完善金融市场的功能,提高企业和商业银行应对外汇风险的能力。     

人民币实际汇率波动对中美贸易收支的影响——基于1990—2009年时间序列分析

基于协整理论、误差修正模型和格兰杰因果检验并根据中国和美国1990-2009年的季度数据,分析人民币实际汇率变动对中美贸易收支的影响.结果表明:影响中美贸易收支的主要因素包括美国的实际GDP、中国的实际GDP和人民币实际汇率,且三者的影响力次第减弱,中美贸易也存在明显的J曲线效应.因此,改善中美贸易失衡应扩大中国内需、调整业口结构和改革人民币汇率制度.     

政府信用创新——基于国债转贷政策的分析

对国债实施转贷是政府信用运作方式的一种创新.理论上,采取有偿方式运用国债资金,有利于提高政府信用资金的使用效率,但是,从审计部门国债资金审计报告及相关文献反映的情况看,这一创新的理论目标与实践效果之间存在明显差距.随着2008年国债转贷资金还本付息高峰期到来,国债资金使用低效问题将会逐步显现成为现实的信用问题,因此,从理论和实践意义上,对以国债转贷政策为内容的政府信用创新进行必要的反思,显然已是恰逢其时.     

加强社保基金管理，提高投资收益

2006年上海社保基金案东窗事发，涉案金额达百亿人民币，由于社保基金牵涉老百姓日后生计，关系到社会稳定，一时之间，该案成为社会关注的焦点。但不可否认，在我国社保资金存在巨大缺口的压力下，将社保基金用于投资赚取收益并没有错。这一案件提醒我们，不能因为社保基金的特殊性，就忽略社保基金的投资管理。随着我国社保基金规模不断变大，投资领域和方式的不断出新，加强社保基金投资管理，非常关键。     

财政收入、财政支出与居民消费率

从财政政策收入分配功能的角度就财政收支对居民消费率的影响进行了理论分析,并采用全国数据和省级面板数据就财政收支对居民消费率的影响进行了实证分析。研究结果表明,我国过高的税负率对我国居民消费率的提高有负面影响,以间接税为主的财政收入结构不能实现社会财富再分配的均等化,不利于促进我国居民消费率的提高。财政消费性支出对居民消费具有挤出效应,而保障性支出有助于提高居民消费率。因此改变财政收支结构,强化财政收支的收入再分配功能是提高居民消费率的关键。     

商业银行资本结构研究

资本结构对于实现商业银行的财务目标和稳健经营起着至关重要的作用.本文从一般的资本结构决定理论出发,探讨银行资本结构决定中的特殊性,最后得出的结论是:政府为银行业提供的担保会促使商业银行提高财务杠杆系数,而监管当局的最低资本充足率要求则限定了商业银行的资本结构选择空间.     

我国人口流动与中央财政转移支付相对力度的区域差异分析

为了缩小东中西部地区的发展差距,中央财政加大了对中西部地区的转移支付力度,但在促进区域经济发展收敛和实现地区财政均等化方面其效果如何,文章试图从一种新的视角加以分析与诠释。改革开放以来大规模的人口跨地区流动,特别是年轻劳动力从中西部地区向发达的东部地区流动,改变了各地区的人口结构和总扶养比,进而影响中央财政转移支付的实际效果。研究结果表明,由于西部地区总扶养比高于东部地区,中央财政对西部地区的转移支付相对力度反而低于东部地区。文章最后提出将地区人口负担差异纳入中央财政预算分析体系,通过增加中央财政对经济落后地区的转移支付促进地区经济增长收敛和提高地区财政帮扶的实效性。     

Institutional determinants of the effective tax rate in G7 and BRIC countries

This paper studies the relationship between the corporate effective tax rate (ETR) and several institutional factors in the G7 and the BRIC countries (Brazil, Russia, India, and China). We use the panel data methodology with a data sample of 25,878 listed firms in 2010–2018. The results show that all the variables analyzed have an effect on the ETR. Some—such as the statutory tax rate, government effectiveness, regulatory quality, rule of law, and open markets—affect all countries, whereas others, such as corruption control and economic freedom, affect only the BRIC countries, and gross domestic product growth, the deficit, and gross debt only affect the G7 countries.     

The impact of government debt on the long-run natural real interest rate – a quantitative evaluation

Persistently low natural real interest rates are a problem for monetary policy and financial stability. I analyse to what extent a permanent increase in government debt that is financed by higher taxes could raise the long-run natural real interest rate. As a measurement tool, I use an incomplete markets model with capital and government bonds. Increasing the public debt/GDP ratio by one percentage point raises the real interest rate by between 0.4 and 1.5 basis points, depending on the degree of inequality generated by the model and the tax instrument used to balance the government’s budget constraint. I also show that the interest rate effect of a change in public debt/GDP predicted by the model is significantly smaller than its empirical counterpart for the US, due to the fact that the model understates the empirical fraction of households that are constrained in their consumption decision.     

Fire sales by euro area banks and funds: What is their asset price impact?

The assets under management of investment funds have soared in recent years, triggering a debate on their possible implications for financial stability. We contribute to this debate assessing the asset price impact of fire sales in a novel partial equilibrium model of euro area funds and banks calibrated over the period between 2008 and 2017. An initial shock to yields causes funds to sell assets to address investor redemptions, while both banks and funds sell assets to keep their leverage constant. These fire sales generate second-round price effects. We find that the potential losses due to the price impact of fire sales have decreased over time for the system. The contribution of funds to this impact is lower than that of banks. However, funds’ relative contribution has risen due to their increased assets under management and banks’ lower leverage and rebalancing towards loans. Should this trend continue, funds will become an increasingly important source of systemic risk.
