Dear researchers, please I would like to ask this question: I have a yearly dataset covering 35 countries and with 3 variables. The idea for the 3 variables is to find a tripartite relationship between the three, e.g., whether A=B=C. Similarly, I want to find whether or not A granger causes B, C in that order. I want to know whether my sample size (N=35, T=14) is too small or not to use Panel VAR. I read pieces of literature, but it seems my sample is too small, and I have been thinking about the options to consider. Please, can you tell me the requirement for the usage of Panel VAR concerning the N and T for yearly data? Thank you.
