Pleаse mаtch the descriptiоn with the cоrrect аnswer. Hint: Strict exоgeneity is stronger than exogeneity assumption and is more likely to be violated. An implication of weakly dependent time series is that the correlation between xt and xt+h is almost must converge to zero if h grows to infinity. For the law of large number (LLM) and the central limit theorem (CLT) to hold, the individual observations must not be too strongly related to each other; in particular their relation must become weaker (and this fast enough) the farther they are apart.
