Blanchard and kahn conditions

Web4.3 Blanchard and Kahn’s Method The first solution method we present was developed by Blanchard and Kahn (1980), and is applied to models written as x1t+1 Et(x2t+1) = A x1t x2t +Ef t, (4.29) where the model variables have been divided into an n1 ×1 vector of endogenous predetermined variables x1t (defined as variables for which WebTo understand how our approach works, it is useful to recall the conditions for determinacy as stated by Blanchard and Kahn (1980). Indeterminacy arises when the parameter values are such that the number of explosive roots is smaller than the number of non-predetermined variables.
