Existence of adaptively stable sunspot equilibria near an indeterminate steady state
Evans, George W.; Honkapohja, Seppo - 2001
We examine the nonlinear model Xt = Et F(xt+1) . Markov SSEs exist near an indeterminate steady state, X = F(X), provided F´(X)> 1. We show that there exist Markov SSEs that are E-stable, and therefore locally stable under adaptive learning, if F´(X)< -1.

Expectational stability of resonant frequency sunspot equilibria
Evans, George W.; Honkapohja, Seppo - 2001
We consider the stability under adaptive learning of the complete set of solutions to the model when . In addition to … relationships between these solutions and show that the stability properties of equilibria may depend crucially on the …

Stable sunspot equilibria in a cash-in-advance economy
Evans, George W.; Honkapohja, Seppo; Marimon, Ramon - 2001
We develop a monetary model with flexible supply of labor, cash in advance constraints and government spending financed by seignorage. This model has two regimes. One regime is conventional with two steady states. The other regime has a unique steady state which can be determinate or...

Are stationary hyperinflation paths learnable?
Adam, Klaus; Evans, George W.; Honkapohja, Seppo - 2003
Earlier studies of the seigniorage inflation model have found that the high-inflation steady state is not stable under adaptive learning. We reconsider this issue and analyze the full set of solutions for the linearized model. Our main focus is on stationary hyperinflationary paths near the...

Stable Sunspot Equilibria in a Cash-in-Advance Economy
Evans, George W.; Honkapohja, Seppo; Marimon, Ramon - Barcelona Graduate School of Economics (Barcelona GSE) - 2003
We analyze a monetary model with flexible labor supply, cash-inadvance constraints and seigniorage-financed government deficits. If the intertemporal elasticity of substitution of labor is greater than one, there are two steady states, one determinate and the other indeterminate. If the...
