Impact of macroeconomic surprises on the Brazilian yield curve and expected inflation

This study investigates how unexpected announcements in Brazilian and U.S. macroeconomic indicators affect the term structure of nominal interest rates, as well as implicit inflation expectations and real interest rates. Using daily data from March 2005 to December 2012, we employ an extended Vector Error Correction Model to take into account nonstationarity and the long-term equilibrium among different maturities of those curves. We found empirical evidence that macroeconomic surprises, domestic (Brazilian) and external (U.S. American), which lead the market to believe that there might be a higher risk of inflation or an overheated economy, raise nominal interest rates, implicit expected inflation and real interest rates. Surprisingly, in relation to the efficient-market hypothesis, we found that some macroeconomic surprises have a lagged effect on the yield curves. We also tested the impact of the global financial crisis of 2007–09 and found that the crisis affected significantly the direction and magnitude of the responses to macroeconomic news.     

Lack of divine coincidence in New Keynesian models

The literature has long agreed that the divine coincidence holds in standard New Keynesian models: the monetary authority is able to simultaneously stabilize inflation and output gap in response to preference and technology shocks. I show that the divine coincidence holds only when inflation is stabilized at exactly zero. Even small deviations from zero generate policy trade-offs. I demonstrate this result using the model׳s non-linear equilibrium conditions to avoid biases from log-linearization. When the model is log-linearized, a non-zero steady state level of inflation gives rise to what I call the endogenous trend inflation cost-push shock in the New -Keynesian Phillips curve.     

Does Money Matter in Shaping Domestic Business Cycles? An International Investigation

We study the contribution of money to business‐cycle fluctuations in the United States, the United Kingdom, Japan, and the euro area using a small‐scale structural monetary business cycle model. Constrained likelihood‐based estimates of the parameters are provided and time instabilities analyzed. Real balances are statistically important for output and inflation fluctuations. Their contribution changes over time. Models giving money no role provide a distorted representation of the sources of cyclical fluctuations, of the transmission of shocks, and of the events of the last 40 years.     

我国通货膨胀过程的社会福利成本度量与经验分析

通过利用1994年至2006年之间的我国GDP、M1和名义利率的季度数据,采用协整检验和回归系数估计方法,获得我国长期货币需求函数,在此基础上对我国通货膨胀的社会福利成本进行了实证分析。实证结果表明,我国较高的通货膨胀率会带来比较大的福利成本,因此,当前通胀压力较大的时期,采取适当的宏观调控措施,将通货膨胀率控制在3%以下的低水平状态。     

通胀预期与物价变化关系实证研究

本文分析了通胀预期的表现形式,重点探讨了通胀预期与物价变化的关系。研究结果显示,通胀预期对不同种类的价格影响程度是不同的,对消费品价格变化影响较小,CPI对通胀预期缺乏敏感;对企业生产品价格影响程度远大于对消费品价格的影响。     

缓解人民币升值压力的思考——巴拉萨-萨缪尔森效应与人民币汇率升值

2005年人民币汇率制度改革以来,人民币升值压力和预期始终没有消除,造成我国宏观经济困境。根据巴拉萨-萨缪尔森效应,随着我国经济的快速追赶,人民币实际汇率有长期升值趋势,而当我国可贸易品部门的单位劳动成本相对下降,这一趋势就通过名义汇率升值压力体现。巴拉萨-萨缪尔森效应提示我们可以通过一般物价水平调整缓解升值压力,即采用温和的结构性通胀策略降低升值预期。这对于稳定我国宏观经济,消除外汇储备泡沫,转变经济结构具有积极作用。     

股价波动、通货膨胀与固定资产投资——基于协整和VEC模型的经验证据

经验证据表明,我国股票市场时全社会固定资产投资的影响作用还比较小,股票市场对固定资产投资的冲击在部分时段是负效应,可能存在部分"挤出效应".而影响固定资产投资的主要因素是GDP的变动.另外在我国,通货膨胀率对固定资产投资的影响比较明显.从短期来看,固定资产投资也带动了通货膨胀.国内固定资产投资的波动不仅受偏离均衡的影响,还受到GDP、Cpi、上证综合指数与存款利率水平自身变动的影响.央行应加强审慎的宏观调控,优化信贷结构,加强农村水利建设的长期投资,为经济结构调整和经济增长方式的转变提供稳定的货币金融环境.     

产能利用不足和通胀压力并存的悖论——从产能角度思考中国经济的深层次问题及对策

从中国经济运行的实证轨迹来看,产能过剩存在于以钢铁等为代表的中上游工业制造业和以部分机械制造行业为代表的中下游工业制造业,近年来在以高速公路、高速铁路和轨道交通为代表的基础设施行业也有所体现.在产能过剩的同时,中国的通胀压力尤其是生产资料价格上涨压力却难以消减.产能利用不足与通胀压力并存的根源值得深入分析.生产要素价格...     

货币政策为何及如何关注食品价格

食品价格是通货膨胀压力的灵敏反映指标,且由于食品部门供应价格弹性、存货缓冲能力、需求价格弹性和生产效率相对较低,产品同质化程度相对较高,食品价格的弹性明显高于非食品价格,加之在通货膨胀和经济周期过程中,食品部门具有需求顺周期和供给逆周期的特征,食品价格波动幅度往往远高于非食品价格,存在一定程度的超调。因此,文章建议货币政策应充分关注食品价格,同时适当提高对食品价格波幅的容忍程度。     

信用评级高估与融资的所有制歧视——基于中国公司债的数据

为了分析发债主体所有制性质对公司债发行定价影响的作用机理,从信用评级高估的假设出发,将所有制性质的定价作用区分为直接效应和间接效应,基于贝叶斯法则得出两个推断：评级高估会导致发债主体所有制性质对公司债发行定价的直接效应;高信用等级公司债发行定价会受到发债主体所有制性质的直接影响,低信用等级公司债则不然。通过对2007—2013年沪深两市公开发行的公司债进行实证分析,推断得到了验证。这些分析有利于剖析民营企业融资歧视的形成机制。
