WebBlanchard and Kahn (1980) showed that a LRE model can be written as a linear combination of backward-looking and forward-looking solutions. Since then, a number of alternative approaches for solving linear rational expecta-tions models have emerged (King and Watson, 1998; Klein, 2000; Uhlig, 1999; Sims, 2001).

Homework Statement I have understood the point with the Blanchard Kahn condition, my problem is to find the explicit solution when I know there exists one unique solution to the problem. The problem comes from a DSGE model. WebIn these both situations the coefficients of the linear approximation of the model are constant and we can apply Blanchard and Kahn's results. The eigenvalues of the second linear approximation are equal to times those of the first.

Web(2) Secondly, later in the text a similar issue recurs in chapter 11.5 when analyzing the model of optimal monetary policy in a forward-looking setting. Romer considers cases where self-fulfilling equilibria arise (I guess Blanchard-Khan conditions): So why do we have to assume that our variable is bounded? Webstable solution under two conditions: (i) there exists a number z such that the determinant polynomial, jAz ¡ Bj, is non-zero; and (ii) a direct generalization of the Blanchard-Kahn rank condition (stated precisely in Section 4 below) is satis–ed.
