How do economic policy uncertainty and geopolitical risk drive Bitcoin volatility?

We investigate how economic policy uncertainty (EPU) and geopolitical risks (GPR) impact Bitcoin volatility with respect to factors related to type and nationality of uncertainty, investigated period, relationship horizon and extreme conditions. Applying ARDL model and quantile regression for monthly data from August 2010 to September 2021, we reveal that June 2014 corresponds to a key date that marks a reversal in the investigated relationship. Furthermore, we show that the relationship between uncertainty and bitcoin volatility changes according to different factors. US uncertainty has short run effects on Bitcoin volatility, while China’s uncertainty has rather long run effects. Moreover, Bitcoin volatility responds in the same manner to US EPU and GPR, while, it responds differently to China's EPU and GPR. In extreme quantiles, we find that Bitcoin hedges against US EPU and GPR. Further, Bitcoin hedges against either individual or joint effects of US uncertainty, but not both.     

Does economic policy uncertainty drive the dynamic spillover among traditional currencies and cryptocurrencies? The role of the COVID-19 pandemic

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.     

国家审计对地方财政支出结构的影响研究

运用国家审计理论,依据2007—2018年中国30个省份相关数据,考量国家审计对地方财政支出结构的影响机制以及财政资金使用效率和财政压力的中介效应。结果表明,国家审计对地方财政支出结构影响显著,国家审计通过提高财政资金使用效率和缓解财政压力两种机制影响地方财政支出结构;同时,财政资金使用效率与财政压力在国家审计提升地方社会性支出占比中发挥链式中介作用。鉴于此,应充分发挥国家审计治理效能,秉持研究型审计新理念,优化地方财政支出结构;开展财政资金绩效审计,提升地方财政资金使用效率。     

网络经济视角下的垄断与中国反垄断改革

网络经济条件下的垄断与传统工业经济中的垄断是不同的,在网络经济条件下,垄断结构更有利于技术进步,更能促进竞争,提高资源配置效率。当前中国反垄断的核心是保护竞争秩序、规制企业的垄断行为,激励企业提高自主创新能力,积极参与国际范围的垄断竞争。
