价格型与数量型货币政策工具比较——基于包含时变通胀目标的DSGE模型

建立包含时变通胀目标的新凯恩斯DSGE模型,研究在分别使用数量型和价格型的货币政策工具的情况下通胀目标变动冲击对中国经济波动的影响。结果显示:在两种情况下,通胀目标变动冲击对通货膨胀和利率的波动均产生重要影响;当使用数量型货币政策工具时,通胀目标变动冲击是导致产出波动的主要因素;整体而言,价格型货币政策工具的调控效果要优于数量型货币政策工具。提出:我国央行应保持货币政策的连续性和稳定性,形成长期稳定的通胀目标,并使货币政策调控模式逐步向价格型调控模式转移。     

The time-varying effect of inflation uncertainty on inflation for Turkey

We investigate the effect of inflation uncertainty on inflation from January 1982 through March 2016 for Turkey by using the Stochastic Volatility in Mean model with time-varying parameters. Our empirical evidence from consumer price index (CPI) inflation suggests that the observed positive relationship between inflation and inflation uncertainty is not robust. This positive relationship diminishes after 2002. This finding is valid for all five subcomponents of CPI inflation; however, for Health Services, Transportation Services, and Recreational and Cultural Services, an inflation-positive association is reported after 2010.     

财政赤字的通货膨胀风险——理论诠释与中国的实证分析

财政赤字与通货膨胀的关系一直是理论界与决策部门密切关注的问题。文章在构建财政赤字与通货膨胀联系机制的理论框架基础上,结合两者在我国宏观经济运行中的客观运行轨迹,对我国财政赤字的通货膨胀风险进行了实证分析。实证结果表明,虽然我国财政赤字在不同的融资方式下均具有一定的货币扩张效应,但由于财政赤字的规模仍然在适度的范围内,财政赤字所引起的货币供给量增加幅度还不足以导致通货膨胀发生,我国财政赤字并不是通货膨胀产生的主要原因。     

中国经济增长与通货膨胀:非典型滞胀特征

近年来,中国的宏观经济运行出现了高增长、低就业并存,资本存量与收入流量失衡的新局面.这种现象无法用传统的典型滞胀理论来解释说明,因此,构建一种针对中国实际情况的分析视角和方法的需要变得更为迫切.基于纯货币经济的分析方法,本文将中国的经济增长与通货膨胀归纳为一种含有非典型滞胀特征的经济现象.     

The Generalized Unit Value Index Family

This study introduces a group of Generalized Unit Value indices that evaluate price level changes. The approach is to transform the original price and quantity data into numbers that all relate to a common unit which provides the same intrinsic worth to the consumers. When, in the transformed data, an equivalence of worth is present, then even incommensurables can be aggregated by the standard unit value method. The group of Generalized Unit Value indices includes some well‐known (Laspeyres, Paasche, Banerjee), barely known (Lehr, Davies), and previously quite unknown price indices. Using a Generalized Unit Value price index as a deflator yields a particularly appealing and useful quantity index.     

Structural vulnerability and resilience to currency crisis: Foreign currency debt versus export

Is there any factor that is not analyzed in the literature but is important for preventing currency crises? I argue that exports are an important factor to prevent currency crises that has not been frequently analyzed in the existing theoretical literature. Using the third generation model of currency crises, I derive a simple and intuitive formula that captures an economy’s structural vulnerability characterized by the elasticity of exports and repayments for foreign currency denominated debt. I graphically show that the possibility of currency crisis equilibrium depends on this structural vulnerability and also analyze how this vulnerability impacts the effectiveness of monetary policy response.     

Central bank independence,inflation and political instability in developing countries

We test whether political instability affects central bank independence in developing countries. Both a legal measure and the turnover tate of central bank governors are used as proxies for central bank independence and the frequency of government transfers is used to proxy political instability. Only the number of coups affects the turnover rate of central bank governors. We also find that both the turnover rate of central bank governors and political instability affect the rate of inflation.     

科技进步与通货膨胀

经济学的本质是研究市场不变下的技术组合,因此科技进步始终是经济研究的焦点,而在经济工业化的快速增长期里,科技进步更值得关注。此外,在工业化快速增长期里同样值得关注的是通货膨胀。因此,科技进步与通货膨胀的关系格外引起经济学家的兴趣。关于通货膨胀的定义以及有关分析,都基于固定替代弹性定律。这令人们想到,从已有的有关通货膨胀模型出发,融入技术的初始陈述,再运用固定替代弹性定律,便可以对科技进步与通货膨胀的基本关系进行分析。结果表明,技术进步会导致经济容量扩大,对货币的需求趋于宽松,在现有的经济学模型和统计手段里,会有助于通货膨胀。     

意外险的需求模式、感觉阈限与通货膨胀率——基于三区制门限回归模型的实证分析

文章基于中国2000-2010年季度数据的实证分析表明,通货膨胀率不仅显著影响意外险需求,而且意外险保费收入增长率与通货膨胀率之间不是简单的线性负相关。首先,意外险需求对通货膨胀率的敏感程度是边际递减的;其次,与通货膨胀风险相比,投保人更加厌恶通货紧缩风险;最后,由于需求模式在门限值附近出现较大改变,可能会冲击意外险市场,当通货膨胀率接近门限值时保险公司应及时调整营销策略。     

从OCA理论看东亚地区货币金融合作的前景

在经济全球化和金融自由化的背景下,国家之间的货币政策协调越来越显得重要,最优货币区理论就是在这一背景下提出的.对东亚地区而言,在东南亚金融危机爆发以后,加强国家之间的货币金融合作的呼声越来越高,并且东亚地区许多方面已经满足了最优货币区的标准.但由于政治上的原因,在东亚地区建立统一货币区的时机还不成熟,因此,东亚地区货币区的建立应该在最优货币区理论的指导下循序渐进地进行.
