WebbTo this end, two new measures of EPU (Twitter-based economic uncertainty and Twitter-based market uncertainty) are considered. A Granger causality test using the recursive evolving window approach shows a significant causality between the Twitter-based EPU measures and the BTC/USD exchange rate from October 2016 to July 2024. WebbSince a rolling window is used, it is a given that the statistical characteristics will change throughout the windows and the sub-samples, the high values would be more common …
WebbThis paper employs a new time-varying causality test based on the recursive evolving window (REW) algorithm and VAR (LA-VAR as well) model proposed by Shi et al. [18,19] to explore the real-time causal relationships between AH stock prices and between AH stock volatilities. This novel time-varying causality test has two advantages for our analysis.
