3. Consider the following non-stationary process: 3t = 7o+y₁t+24. with uput-1+ and ei.i.d. ². Indicate (with explanation) the source(s) of non-stationarity of y. Show that you can rewrite the model as: Ayt = Bo+B₁t+ B₂3t-1 + Et. Clearly indicate the one-to-one relation between (Yo. 71, P) and (Bo.B1, B₂). What name do we give the non-stationary process yt when p= 1? Briefly indicate how to test whether this is the case.
