This study examines the time-frequency co-movement and network connectedness between green bonds and other financial assets in China. We propose wavelet coherence and multiscale TVP-VAR to explore the time-frequency co-movement and spillover connectedness. The empirical results are as follows. First, green bonds positively co-move with conventional bonds across time scales and negatively co-move with stocks and commodities. Second, there is a significant network connectedness of green bonds with conventional bonds in the short term, and the connectedness with stocks and commodities gradually strengthens with the increase in time scales. Third, the dynamic spillover between green bonds and other assets is much greater in the long and medium terms than in the short term. Finally, under crisis shocks, the spillovers spike temporarily in the short term, while they are persistent and at a high level in the long term. Overall, some practical implications are proposed for investors and policymakers. 相似文献

This study analyzes the overall and time-varying effects of global and domestic uncertainty on the Korean economy by estimating constant parameter and time-varying parameter vector autoregressive models. Global and Korea-specific uncertainty are measured using the method proposed by Mumtaz and Theodoridis (2017). A rise in both the uncertainty measures has an adverse impact on the Korean economy by lowering stock market returns and output growth, and by creating inflation caused by currency depreciation. Quantitatively, the domestic uncertainty shock exercises a larger effect on the Korean economy than the global uncertainty shock, as the former uncertainty shock accounts for about one-fifth of output variation and the latter accounts for about one-tenth. Regarding time-varying effects, substantial increases in domestic uncertainty during the Asian Financial Crisis and global uncertainty during the Global Financial Crisis explain a significant part of macroeconomic fluctuations in Korea during those periods. This is because of the increased volatility of uncertainty shocks during these periods, rather than a structural change in the way these shocks affect the economy. 相似文献

Many central banks have now developed their digital currencies in response to the challenges posed by the proliferation of decentralised digital cryptocurrencies. However, little is known about the effects of the introduction of central bank digital currencies (CBDCs) on extant digital cryptocurrencies. This paper, therefore, aims to identify both the time- and frequency-domain spillover effects among cryptocurrency markets and a newly developed central bank digital currencies attention index (CBDCAI) by using two TVP-VAR-based spillover models. Our results demonstrate that CBDC attention significantly impacts cryptocurrency markets. Also, most investors in cryptocurrency markets are more likely to trade in the short term. The results of this study contribute to helping investors and investment institutions effectively avoid investment risks, reduce losses, and predict the return of some cryptocurrencies. Also help policymakers better understand the impact of markets and policies, and provide a reference for them to formulate policies. 相似文献

保险业促进经济发展的相关理论及由实践经验数据所得结论并未达成一致共识,部分学者认为保险业的发展有助于推动经济增长;同时也有部分学者认为保险业的经济助推作用并不明显。本文基于1999~20丨7年财险和寿险月度数据,运用时变参数向量自回归模型(TVP-VAR)研究保险业对经济增长的促进作用,得出如下结论:整体上,保险业对经济增长能够产生促进效应,并且随着保险业的发展,促进作用愈发显著;财险和寿险的发展均对经济增长产生显著地直接促进作用,在不同的期限结构时点,其持续程度与显著程度不同;此外,保险业对经济增长还存在持续的间接促进作用。该结论对于新常态下的保险监管政策制定者存在一定借鉴意义。 相似文献

The paper examines the dynamic spillover among traditional currencies and cryptocurrencies before and during the COVID-19 pandemic and investigates whether economic policy uncertainty (EPU) impacts this spillover. Based on the TVP-VAR approach, we find evidence of spillover effects among currencies, which increased widely during the pandemic. In addition, results suggest that almost all cryptocurrencies remain as “safe-haven” tools against market uncertainty during the COVID-19 period. Moreover, comparative analysis shows that the total connectedness for cryptocurrencies is lower than for traditional currencies during the crisis. Further analysis using quantile regression suggests that EPU exerts an impact on the total and the net spillovers with different degrees across currencies and this impact is affected by the health crisis. Our findings have important policy implications for policymakers, investors, and international traders. 相似文献

基于TVP-VAR模型对结构性货币政策、金融杠杆与经济增长三者关系进行动态识别,并结合我国“去杠杆”的特殊时点进行补充性分析。研究发现：MLF在单独调节金融杠杆、实现经济增长方面的执行效果优于其他工具,而整体上数量型工具的调控幅度和持续性优于价格型工具;“结构性货币政策—金融杠杆—经济增长”间接作用机制表明,短中期内稳杠杆措施加剧了金融体系的脆弱性,对经济发展产生负面影响,而结构性货币政策的长期效应能够通过持续、精准调控金融杠杆促进经济平稳增长。据此,应把握“灵活适度”“精准导向”原则,逐步扩大结构性货币政策的覆盖范围和使用频率。同时,深化金融体制改革,强化宏观审慎管理。 相似文献

依据铜、铝和锌三种典型性基本有色金属在金融危机前后的期货价格波动数据,运用分解-合成框架和时变TVP-VAR分析模型,考量影响基本有色金属期货价格波动重大事件和长期趋势价格波动的因素及价格时变特征。结果发现:铜、铝和锌三种基本有色金属期货的价格走势基本一致,且与中国宏观经济密切相关,其价格的最低点都出现在金融危机期间,而价格的最高点基本都出现在经济繁荣期;基本有色金属价格存在同涨同跌关系,而且涨跌幅基本趋势相一致。鉴此,可以对具有周期变化特征的基本有色金属价格走势进行预测,并规避价格波动的风险。 相似文献

为了揭示中国金融体系与宏观经济运行的系列结构性变化及其关联动态,文章分别基于货币流动性宽松程度、剩余收益模型以及银行资产负债表,对中国货币市场、股票市场与银行体系的风险进行了测度和评估;并在分析上述三个金融子市场风险变动规律及其传递机制的基础上,运用时变参数向量自回归模型实证检验了各金融市场风险与宏观经济景气之间的关联动态。研究发现:在金融危机爆发前后,不同金融市场风险之间的传递关系发生了重要转变,并且与宏观经济景气变动之间的交互影响也存在显著的阶段性差异,呈现出\"良性循环\"与\"恶性螺旋\"的非对称性切换。这些研究为中国新时期积极转变宏观经济调控政策决策机制、创新宏观经济调控与金融监管模式,实现宏观经济与金融体系的双重稳定提供了有益的经验依据与政策启示。 相似文献

本文利用主成分分析方法计算出中国的金融形势指数,以此考察了中国金融周期的波动特征,并进一步运用时变参数向量自回归模型分析中国金融周期波动对宏观经济的时变影响及其非对称性特征。研究结果表明,中国金融周期波动先行于宏观经济景气波动,周期长度大致为3年,且存在长扩张短收缩的非对称性特征;金融冲击的“产出效应”不如“价格效应”明显,金融形势好转所产生的加速效应比金融形势恶化所带来的负面影响更为显著。 相似文献

This paper examines the role of monetary policy (MP) as a driver of connectedness patterns in speculative activities in financial markets. Examining measures of speculation in four major markets including gold, equities, Treasury bonds and crude oil, we show that speculative activities can spill over across markets with the stock market generally serving as the main transmitter of speculative shocks. While unconventional MP is associated with greater connectedness of speculative activities in financial markets, we also find that unconventional (conventional) MP drives gold (financial assets) to serve as a net transmitter of speculative shocks to the other markets. The findings establish an important link between the monetary policy signals and trading behavior in financial markets with significant policy implications. 相似文献
