I am a econometrics student, and I've to understand what type of process the one in the image below is. I am not able to go back to the main classic stochastic processes (AR, MA, ARMA, ARCH/GARCH). In particular, the fact that epsilon is multiplied and not added generated confusion in me. Epsilon is a Gaussian white noise Thanks!
