上海股票、债券和基金市场的联动性——基于DCC-MIDAS的实证

运用DCC-MIDAS模型和GARCH-MIDAS模型,深入研究了上海股票、债券和基金市场间的联动性及宏观不确定性对收益率波动的影响。结果表明,股市与基市具有高度的长期和短期正相关性;债市与股、基两个市场的长期相关性较小,短期相关远大于长期相关且呈现大幅波动和频繁的正负转换;货币供应量和工业生产指数对三个市场的收益率长期波动产生正向影响,经济政策不确定性指数的影响则是负向。且宏观不确定性变量对股市和基市的影响显著大于债市。     

宏观经济波动对股票市场的影响分析——基于协整分析与误差修正模型

在有效市场前提下,宏观经济波动对股票市场的冲击会反映在股票价格的变化上,为了研究两者的具体关系,选取2000~2016年上证综合指数与宏观经济相关变量的时间序列数据,运用单位根检验、协整检验以及构造协整方程、误差修正模型的方法对宏观经济波动对股票市场的冲击进行实证分析,结果表明,股票市场反映宏观经济波动的预期并不一致,宏观经济波动与股票市场波动出现了明显的背离,而且短期各个宏观经济变量对股票市场波动的影响大小和显著程度与长期的并不一致,研究结果表明在短期宏观经济变量对股票市场波动的冲击较大。     

基于层次聚类降维模型推测股票组合持仓的研究

股票组合中成分股的构成与权重反映了基金经理的投资策略与投资风格,在实践中,这些信息往往存在披露频率低、披露时间滞后以及有限披露的问题。通过研究提出了一种基于二次规划的层次聚类降维模型,能够仅根据样本空间股票与投资组合的历史收益率,快速估算出股票组合当前成分股的构成与权重。同时选择上证50指数验证模型的效果,发现样本区间内,层次聚类降维模型能够从A股全部样本空间几千只股票中,平均估算出上证50指数50只实际成分股中的29.3只股票,对高权重成分股预测精度约为73%,优于二次规划模型。另外,市场结构分化越显著,层次聚类降维模型相对二次规划模型的改进效果越明显。模型的有效性验证了A股市场分层聚类的结构特征。     

股票价格、房地产价格和我国货币需求的实证分析

本文通过引入股票价格和房地产价格,实证分析了资产价格对我国货币需求关系的影响。协整分析表明,房地产价格对长期货币需求有显著的替代效应,股票价格因素不显著。可变参数误差修正模型分析表明,我国的转轨经济特性使得各经济变量对短期货币需求的影响呈现动态变化的特征,同时金融深化和创新也加快了公众对长期货币需求偏离的修正速度。     

中国的货币流动性分析

货币流动性(M1/M2)测度了货币供应内部的活跃程度,是宏观经济分析中普遍关注的重要变量之一。本文着重对中国货币流动性相对稳定期间(1997～2010年)的情形进行分析,探寻货币流动性的影响因素及其经济内涵。文章发现,近年来工业增加值的增加和股指的高企引发了货币活化程度的提高。实际利率对货币活化水平有短期负向作用,但其影响系数和显著性有限,这可能与我国利率尚未完全市场化有关。实际利率与货币活化却存在长期正向关系,这很可能与"金融深化"有关,即长期内实际利率的提升有助于解除资金价格扭曲和金融抑制,增加货币活化程度。随着中国经济金融的不断发展,影响货币活化的因素必将不断演变,时常考察其决定因素,有助于为宏观分析提供有价值的经济信息,并为前瞻性的宏观金融调控提供决策支持。     

新特里芬悖论的逻辑辨析及对中国的启示

本文从特里芬悖论的原意出发提出新特里芬悖论概念,通过协整检验和构建向量误差修正模型（VECM）,建立美元实际有效汇率与货币供应量、国际资本收支之间的长期均衡和短期动态关系,并利用脉冲响应函数和方差分解原理分析变量短期波动给美元实际有效汇率的冲击。本文分析表明,新特里芬悖论产生的问题对实际经济活动影响有限,当世界各国的美元需求增长可持续时,当前以美元为主导的国际货币体系不存在根本性矛盾,新特里芬悖论并不能作为美元贬值政策的理论依据,这也对人民币国际化和外汇政策有长期的借鉴意义。     

国际环境变动对我国货币需求的影响及启示

基于Engle-Granger两步法和引用虚拟变量的方法,采用1992年到2009年的季度数据为样本,分别就20世纪90年代末和21世纪初的两次国际金融危机对我国货币需求稳定性是否产生影响做出检验。结论是1997年亚洲金融危机的影响力度较大,而2008年的金融危机对此影响并不显著。在此基础之上,采用协整的方法,寻求到新的稳定的长期货币需求方程。并且,通过建立误差纠正模型考察了我国短期货币需求的动态变化,并从中发现狭义货币m1更能反映我国货币政策对短期货币需求的控制情况,应将m1作为货币政策的反应变量。最后,本文指出只有灵活、及时地将货币政策和财政政策相结合,增强人民的信心,拉动内需才能应对外来环境的变化,促进经济的平稳发展。     

我国广义货币供应量M2的回归模型与预测

货币供应量是货币政策工具重要的中介变量。该文通过分解我国货币供应量的诸多宏观影响因素，尝试建立一个较为完整的货币供应量多变量回归模型，揭示宏观经济变量对货币供应量的影响程度，并运用该模型对货币供应量的短期变化进行预测，以期为把握宏观经济形势、理解货币政策变化及预判金融市场走势提供参考依据。检验结果表明，该模型对货币供应量的预测比较符合实际情况。     

陕西省货币需求分析与实证研究

本文在对陕西省货币需求相关统计数据分析的基础上,采用单位根检验、协整检验并建立误差修正模型的方式,对陕西省货币需求总量与机会成本变量、规模变量之间的函数关系进行实证研究。结果表明陕西省货币需求与收入、利率以及预期通胀率之间存在长期的稳定关系,而在短期动态模型中,收入与利率的调节功能较显著。     

国际金融市场长短期波动的外溢方向、传递强度和影响因素分析

近年来,由于经济贸易联系不断加强,不同经济体金融市场的联系也在不断加强。本文选取了1996—2019年美国、英国、德国、日本、中国香港地区、澳大利亚、中国七个经济体的金融市场数据,利用GARCH-MIDAS模型分离长期和短期风险,并采用TVP-VAR模型的脉冲响应函数进行广义方差分解,构造波动溢出矩阵,衡量风险传递方向和程度以及经济体各自的溢出作用和吸收作用,分析风险相互传递的情况;通过计算出风险净溢出指数,分析经济体之间净溢出指数趋势的变化。本文选取市场行为和宏观经济基础两类指标,采用面板回归研究分析出长短期净溢出指数的影响因素,实证发现波动占比较大的短期风险的溢出比长期风险严重,而突发性金融事件会使得净溢出指数不断上升;在面板回归中,短期净溢出指数金融压力指数和汇率指数与短期净溢出指数之间呈现负相关关系,其余指标呈现正相关关系;市场行为对长期净溢出指数的影响不显著。     

Money demand heterogeneity and the great moderation

A forward-looking model of the demand for money based on heterogeneous and sluggish-portfolio adjustment can simultaneously account for the low short-run and high long-run semi-elasticities reported in the literature. The parameter estimates from the model for the short-run and long-run interest semi-elasticities are 1.04 and 13.16, respectively. A simulated version of the model suggests that the Great Moderation can be partially attributed to financial innovations in the late 1970s. When moving toward a more flexible portfolio, the model can account for almost one-third of the observed decline in the volatilities of output, consumption, and investment.     

Investigating M3 money demand in the euro area

Euro area monetary growth has exceeded its target since 2001. Likewise, recent empirical studies did not find evidence in favour of a stable long-run money demand function. In contrast to the bulk of the literature, we are able to identify a stable long-run money demand relationship. This result is obtained when the analysis is done without the short run homogeneity restriction between money and prices. The basic equation can be improved by allowing for asymmetric adjustment. In a low inflation environment, opportunity costs of holding money have decreased. Thus, the apparent monetary overhang is reconciled within standard models.     

ON THE DYNAMIC RELATION BETWEEN STOCK PRICES AND EXCHANGE RATES

Abstract In this study we apply recent advances in time-series analysis to examine the intertemporal relation between stock indices and exchange rates for a sample of eight advanced economies. An error correction model (ECM) of the two variables is employed to simultaneously estimate the short-run and long-run dynamics of the variables. The ECM results reveal significant short-run and long-run feedback relations between the two financial markets. Specifically, the results show that an increase in aggregate domestic stock price has a negative short-run effect on domestic currency value. In the long run, however, increases in stock prices have a positive effect on domestic currency value. On the other hand, currency depreciation has a negative short-run and long-run effect on the stock market.     

The demand for eurozone stocks and bonds in a time-varying asset allocation framework

This paper analyzes the short and long-run demand for traditional financial asset classes in eleven founding eurozone members. Our sample period starts from the introduction of euro till 2017. We calculate the welfare losses stemming from ignoring the demand for domestic and eurozone equities and bonds, for various levels of risk aversion. Our results show that the bonds of eurozone countries are, in general, desirable for short-run only. However, in Ireland, Portugal and Spain the bonds are desirable for both short-run and long-run investment horizons. Stocks exhibit both short-run and long-run desirability for all countries except Greece. The Greek stocks are desirable for short- run only.     

Short-run money demand

The conventional wisdom holds that the short-run demand for money is unstable. This paper challenges the conventional view by finding a stable demand for M1 in U.S. data from 1959 through 1993. The approach follows previous work in interpreting long-run money demand as a cointegrating relation, and it uses Goldfeld's partial-adjustment model to interpret short-run dynamics. The key innovation is the choice of the interest rate in the money demand function. Most previous work uses a short-term market rate, but this paper uses the average return on “near monies”—the savings accounts and money market mutual funds that are close substitutes for M1. This choice helps rationalize the behavior of money demand; in particular, the increase in the volatility of velocity after 1980 is explained by increased volatility in the returns on near monies.     

The dynamic relationship among the money market mutual funds,the commercial paper market,and the repo market

In this paper, we present the short-run and the long-run relationships among the financial assets of the money market funds, the commercial paper market, and the repurchase agreement market by undertaking a cointegration analysis of quarterly data over the 1985–2017 period. This was based on the empirical observation that the commercial paper and repo markets account for 50 percent of the assets of money market funds. The evidence suggests that there exists a common long-term cointegrating trend among these three components of the shadow banking system. Any disequilibrium in this long-run relationship among these variables is corrected by movement in the financial assets of money market funds. The Beveridge-Nelson decomposition from the estimated cointegrating relationship shows that the cyclical component of money market funds is large and captures huge swings in these markets during the financial crisis. We also find evidence of change in these dynamic relationships in the post-crisis period, where in addition to the money market funds, the commercial paper market also exhibits a tendency to correct for the disequilbrium.     

Output–employment relationship across employment status: evidence from Turkey

This paper investigates output–employment relationships across different employment statuses and formal versus informal employment divisions for Turkey. Even if we fail to find a long-run relationship between aggregate output and total employment, there are long-run relationships between the aggregate output with all of the formal employment statuses. A further investigation for short-run relationships reveals no statistically significant relationships between aggregate output and total employment and between aggregate output and casual employment but there is a significant short-run relationship between aggregate output and total regular employment. Thus, a sustainable economic growth policy should aim to create formal and regular employment.     

Asymmetric Cointegration,Nonlinear ARDL,and the J-Curve: A Bilateral Analysis of China and Its 21 Trading Partners

This article follows the nonlinear Autoregressive Distributed Lag (ARDL) error-correction methodology to explore nonlinearity in the relationship between the trade balances and the real exchange rates for China and its 21 partners. We find evidence for short-run asymmetric effects of exchange rate in cases of 18 partners, short-run adjustment asymmetry in cases of 11 partners, short-run cumulative asymmetry in cases of seven partners, and a significant long-run asymmetric effect cases of five partners. We find support for the “J-curve” that is only due to appreciation or depreciation of the Yuan in cases of five partners, including the U.S.     

Long-run dynamics of official and black-market exchange rates in Latin America

This paper attempts to investigate the long-run dynamic relationship between official and black-market exchange rates for four Latin America markets namely, Argentina, Brazil, Chile, and Mexico. We follow (Moore, M. J., & Phylaktis, K. (2000). Black and official exchange rates in the Pacific Basin: Some tests of dynamic behaviour. Applied Financial Economics, 10, 361–369.) and we distinguish between long-run informational efficiency and short-run predictability in a sense that these notions are compatible with cointegration and error-correction mechanisms (ECM). Our findings indicate a constant black-market premium for each country, which is taken as strong support for long-run informational efficiency between the official and black markets for foreign currency. In addition, the evidence of short-run predictability is not considered as a violation of market efficiency, but it is the outcome of optimal arbitrage by rational economic agents.
