Inclusion of lagged dependent variable in regression

WebMany variables that have an effect on included endogenous variables also have a direct effect on the dependent variable. IV estimators are innately biased, and their ﬁnite-sample properties are often problematic. Thus, most of the justiﬁcation for the use of IV is asymptotic. Performance in small samples may be poor. WebFor example, eqn [1] has one right-hand-side endogenous variable (P) and one excluded exogenous variable (Z). When the number of included endogenous variables is equal to the number of excluded exogenous variables, then the equation is just identified.
