From the initial idea, writing, submitting, and reviewing to the online presentation of a research paper takes a long time. The identified intellectual structure of a research paper may have a certain time lag. In view of this problem, scholars have suggested that research grants may be an alternative way to identify intellectual structure as early as possible. However, these comments are mentioned qualitatively. Few researchers have verified the research grant by early identification of the int...

ABSTRACTThis paper provides evidence for the impact of oil price shocks on economic policy uncertainty (EPU) from a multi-scale perspective using discrete wavelet transform and VAR model. Results indicate that oil price shocks impose a positive effect on EPU at an original level while effects of oil price shocks on EPU are time-varying over different time-scales. Particularly, oil price shocks lead to a positive change in the trend of EPU in the short- and long-term. Whereas, in the medium term,...

Abstract Dynamic interactions between policy uncertainty and economic activity, including oil prices, have attracted increasing amounts of scholarly interest, but few studies have considered the inherent feature that the entire market is composed of different stakeholders operating in different time horizons. To fill this gap and address this issue, this paper proposes a multi-scale correlation framework. Specifically, we use the wavelet coherence method and scale-by-scale linear Granger causali...

Ways to accurately identify and measure systemic risk of oil imports continues to be the focus of intense research because of the increasing importance of energy security. This study reexamines the risk of oil imports from the perspective of global oil supply chain (OSC) and designs a standardized framework of four risk factors, that is, availability, accessibility, affordability and acceptability risk. The former three factors reveal the internal physical disruption risk of OSC and the last des...
