In the study, the Granger causality test and an augmented autoregressive distributed lag (ARDL) bound test were used.
WebNov 13, 2024 · Granger Causality tests try to determine if one variable(x1) can be used as a predictor of another variable(x2) where the past values of that another variable may or may not help.

WebOct 12, 2015 · In the end, we find that lag = 2 is the best fit according to AIC and BIC. We subsequently test for Granger causality (Wald-test) and indeed we find a causality ( X → Y 0.04** vs Y → X 0.56). However, if we apply the Impulse Response Function (IRF) of the VAR, we see that the most significant shock seems to be at lag = 4.
