We show how to use Hurwitz polynomials to study the stability and uniqueness of Rational Expectation equilibria (REE) in Dynamic General Equilibrium models (DGE). We apply this method to a model characterized by sticky wages and prices and by limited asset market participation (LAMP). We prove analytically in a fourth-order dynamics system that, once nominal wage stickiness is taken into account, LAMP does not invalidate the Taylor Principle.
