Blanchard and kahn's condition
WebDi erence equation with no initial conditions Consider the following equation, with no initial condition x t+1 = ˆx t assume the model cannot explode. Then we have: ˆ>1, unique solution with x t= 0 for all t: ˆ= 1, many solutions. ˆ<1, many solutions. BK method Blanchard-Kahn method.

Webframework by expanding the y vector. This paper’s analysis is similar to that of Blanchard and Kahn (1980) with four important differences: (i) They assume regularity conditions as they proceed that leave some models encoun-tered in practice outside the range of their analysis, while this paper covers all linear models with expectational ... WebNov 21, 2015 · Blanchard Kahn conditions are not satisfied: no stable equilibrium So I think this is an issue about dynare syntax (about which I will happily admit I may be confused), not about the mathematics of difference equations. I am hoping there is some trick that allows me to change the timing of what information the decision-maker has, that …
