In order to challenge the existing literature that points to the detachment of Bitcoin from the global financial system, we use daily data from August 17, 2011–February 14, 2020 and apply a risk spillover approach based on expectiles. Results show reasonable evidence to imply the existence of downside risk spillover between Bitcoin and four assets (equities, bonds, currencies, and commodities), which seems to be time dependent. Our main findings have implications for participants in both the Bitcoin and traditional financial markets for the sake of asset allocation, and risk management. For policy makers, the findings suggest that Bitcoin should be monitored carefully for the sake of financial stability. 相似文献

This study examines why most derivatives markets that settle on the day following expiration choose the opening rather than the closing price as the final settlement price (FSP), whereas most markets that settle on the expiration day select an average rather than a single price as the FSP. Four exogenous changes in the Taiwan Futures Exchange settlement procedures provide an experimental basis for studying the settlement procedures’ impact on underlying assets. Greatest market efficiency is observed when the FSP is determined by a single rather than an average price and hypothesize that manipulation is prevented at the expense of market quality. 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

技术特征不同行业中FDI技术外溢效果的考察——基于非参数分析方法的研究 总被引:3,自引:0,他引:3
本文通过非参数性方法得到全要素生产率,考察了FDI对我国工业行业技术进步的影响。发现FDI外溢效果在科技含量高的行业中较为明显,在低科技行业中效果较差。并且通过进一步观察发现在外溢效果显著的行业中,技术外溢效果的显著性排名与行业中内资部门的技术进步排名高度吻合。因此我们应调整引资结构,吸引更多外资流入高科技行业以促进我国技术进步。 相似文献

Volatility forecasts aim to measure future risk and they are key inputs for financial analysis. In this study, we forecast the realized variance as an observable measure of volatility for several major international stock market indices and accounted for the different predictive information present in jump, continuous, and option-implied variance components. We allowed for volatility spillovers in different stock markets by using a multivariate modeling approach. We used heterogeneous autoregressive (HAR)-type models to obtain the forecasts. Based an out-of-sample forecast study, we show that: (i) including option-implied variances in the HAR model substantially improves the forecast accuracy, (ii) lasso-based lag selection methods do not outperform the parsimonious day-week-month lag structure of the HAR model, and (iii) cross-market spillover effects embedded in the multivariate HAR model have long-term forecasting power. 相似文献

基于前瞻性指引溢出效应的相关理论,选取17个代表性新兴市场国家为研究对象,运用面板向量自回归(PVAR)模型实证分析美联储前瞻性指引对新兴市场国家的溢出效应.结果表明:美联储前瞻性指引在短期内对新兴市场国家金融市场具有一定的冲击,在长期内对新兴市场国家经济增长存在滞后的正向作用.新兴市场国家应采取应对策略,做好风险识别和预警,加强预期管理,增强货币政策协调和合作,有效防范和化解外溢影响. 相似文献

不良贷款约束下的中国银行业全要素生产率增长研究 总被引:13,自引:0,他引:13
本文运用共同边界Malmquist-Luenberger生产率指数测度了2004—2009年中国27家商业银行在不良贷款约束下的全要素生产率增长及其成分,并对影响全要素生产率增长的宏观经济因素进行了实证分析。本文的主要结论有:在表示偏离共同边界的技术落差比率方面,国有商业银行呈"V"型,股份制商业银行较平稳,城市商业银行逐步上升;总体上,中国银行业的全要素生产率是进步的,纯技术进步是推动全要素生产率进步的主要动力,纯技术效率变化和规模效率变化进步都不明显,技术规模变化显示中国银行业趋向CRS边界;股份制商业银行的纯技术赶超最优,而潜在技术相对变动方面表现较弱;外资银行进入和固定资产投资增加对银行全要素生产率提高有推动作用。 相似文献

This paper introduces an agent-based simulation model to study the technological development, the economic performance of
firms and the evolution of agglomerations in a differentiated industry. The analysis is based on the interaction and behavior
of firms, which might share knowledge but at the same time are competitors on the goods markets. Firms do not only compete
with quantities they can also introduce process and product innovations. The level of knowledge of a firm describes the capabilities
to perform innovations. Knowledge can be accumulated by investing in R&D and by knowledge spillover, which depend on geographical
and technological proximity. Simulation runs show that there is an incentive to agglomerate in young industries and that geographical
proximity enhances innovation, especially the number of product innovations.
