Stable Sunspot Equilibria in a Cash-in-Advance Economy∗
نویسندگان
چکیده
We analyze a monetary model with flexible labor supply, cash-inadvance constraints, and seigniorageand tax-financed government spending. If the intertemporal elasticity of substitution of labor is greater than one, both determinate and indeterminate steady states exist. If the elasticity is less than one, there is a unique steady state, which can be indeterminate. Only in the latter case do there exist sunspot equilibria that are stable under adaptive learning. A sufficient reduction in government purchases or increase in tax rates eliminates the sunspot equilibria in many cases. However, raising taxes enough to balance the budget can fail to achieve determinacy. JEL classifications: C62, D83, D84, E31, E32

Sunspots in a Cash-in-Advance Model: A Quantitative Assessment
Does consideration of sunspot equilibria in the cash-in-advance model help the model match key features in the US macroeconomic data? One can use the cash-in-advance model to generate predictions of macro time series via an equilibrium of the model. However, when restricted to minimum state variable stationary rational expectations equilibria, the model’s predictions do not match the data well....
متن کاملTemporary bubbles in an economy with under-accumulation
This paper studies the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each date the economy can experience two different regimes. In the first one the cash-inadvance constraint is binding and money is a dominated asset. In the second one, the constraint is strictly satisfied and money has the same return as capital. When the seco...
متن کاملStable near-rational sunspot equilibria
A new class of near-rational sunspot equilibria is identified in economies expressed as non-linear forward-looking models. The new equilibria are natural extensions of the usual sunspot equilibria associated to the linearized version of the economy, and are near-rational in that agents use the optimal linear forecasting model when forming expectations. A generic existence result is established....
متن کاملSticky Prices and Indeterminacy
The aim of the present paper is to analyze the link between price rigidity and indeterminacy. This is done within a cash-in-advance economy from which we know that it exhibits indeterminacy at high degrees of relative risk aversion. I Þnd that price stickiness reduces the scope of these sunspot equilibria: sluggish price adjustment requires degrees of relative risk aversion compatible with inde...
متن کاملCARESS Working Paper 00-08 REDUCING OVERLAPPING GENERATIONS ECONOMIES TO FINITE ECONOMIES
This paper establishes in a general way the existence of a connection between the stationary equilibria of an infinite horizon economy and the equilibria of a naturally related finite economy. More specifically, the connection is established first between the cycles of a stationary overlapping generations economy and the equilibria of a related finite economy with a cyclical structure. Then the...
