Webb15 juni 2024 · The rank condition is a necessary and sufficient condition for a set of simultaneous equations in an econometric system to allow identification of all its parameters from the estimated coefficients of the reduced form equations. The condition simply requires the matrix of all structural equations of the model to have full rank . See … WebbThe same rank condition for identification holds for stationary and nonstationary data and some sort of instrumental variable estimators will have to be employed to yield consis tency. However, nonstationarity does raise issues of inference if the rank of cointegration or direction of nonstationarity is not known a priori.
