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 the fundamentals solution, the literature describes both finite-state Markov sunspot solutions, satisfying a resonant frequency condition, and autoregressive solutions depending...

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.

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.; Honkapoja, 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...

Money and prices under uncertainty

Nakajima, Tomoyuki; Polemarchakis, Herakles - 2001

remains indeterminacy indexed by an arbitrary probability measure over the set of states of the world. With an interest rate … policy, and only if the asset market is complete, indeterminacy is nominal: it affects prices, but not the allocation of … resources at equilibrium; with a money-supply policy, the indeterminacy is real. Portfolio policy sets the portfolio of assets …

Unemployment and indeterminacy

Nakajima, Tomoyuki - 2003

Using an efficiency-wage model, we examine the relationship between indeterminacy and unemployment insurance. It is … indeterminacy. Our result is based on the fact that the no-shirking condition with marginal utility ofw ealth kept constant is …

The optimal inflation rate and firm-level productivity growth

Weber, Henning - 2012

Empirical data show that firms tend to improve their ranking in the productivity distribution over time. A stickyprice model with firm-level productivity growth fits this data and predicts that the optimal long-run inflation rate is positive and between 1.5% and 2% per year. In contrast, the...

Can taxes stabilize the economy in the presence of consumption externalities?

Lloyd-Braga, Teresa; Modesto, Leonor - 2012

Considering a finance constrained economy, we discuss the stabilization role of variable labour and capital income taxes under a balanced-budget rule in the presence of consumption externalities of the keeping up with the Joneses type. We find that sufficiently procyclical labor and/or capital...

How to escape a liquidity trap with interest rate rules

Duarte, Fernando - 2016

I give necessary and sufficient conditions under which interest-rate feedback rules eliminate aggregate instability by inducing a globally unique optimal equilibrium in a canonical New Keynesian economy with a binding zero lower bound. I consider a central bank that initially keeps interest...
