It has come to the attention of the publisher that article by Forgione, A.F., Migliardo, C., Otranto, E., Scaffidi Domianello, L. (2025), “The impact of WTI futures on Shanghai crude futures: identifying spillover effects on crude oil prices using the multiplicative error model”, Journal of Economic Studies, Vol. 52 No. 9, pp. 215-233, https://doi.org/10.1108/JES-02-2025-0132, contains errors in the set of equations in the final PDF.The corrected equations are:xt=μtϵt,ϵt∼Gamma(a,1/a) ∀ tμt=ω+αxt−1+βμt−1xt=μtεt,εt∼ Gamma(a,1/a) ∀ tμt=ζt+ξtζt=ω+αxt−1+βζt−1ξt=δzt−1xt=μtεt,εt∼ Gamma(a,1/a) ∀ tμt=ζt+ξt+ηtζt=ω+αxt−1+βζt−1ξt=δzt−1ηt=γ rt−1xi,t=μi,tεi,tεi,t∼ Gamma(a,1a) ∀ i=1,…,Nt and t=1,…,Tμi,t=ζi,t+ξi,t+τtζi,t=ω+αxi−1,t+βζi−1,tξi,t=δzi−1,tτt=θ ∑k=1Kφk(λ1,λ2)xt−kφk(λ1,λ2)=[(kK)λ1−1 (1−kK)λ2−1][∑j=1K(jK)λ1−1 (1−jK)λ2−1]xt=μt,stεt,st,εt,st∼ Gamma(ast,1ast) ∀ tμt,st=ξst+ζtξt,st=δstzt−1ζt=ω+α xt−1+β ζt−1xt=π8×(ln⁡Pth−ln⁡Ptl)where π8.The publisher asks that affiliation be entered correctly at submission and confirmed at article proofing stage.
