Abstract In this paper we use a modified neoclassical business cycle model to test two competing explanations of the expansion of the 1990s. The model can have indeterminate, multiple equilibria that give rise to expectation-driven business cycles. We fit into the model series of estimated...

We examine determinancy and expectational stability (learnability) of rational expectations equilibrium (REE) in sticky price New Keynesian (NK) models of the monetary transmission mechanism. We consider three different New Keynesian models: a labor-only model and two models that add capital --...

In this paper we use a modified neoclassical business cycle model to test two competing explanations of the expansion of the 1990s. The model can have indeterminate, multiple equilibria that give rise to expectation-driven business cycles. We fit into the model series of estimated speculative...

We introduce increasing returns to scale into an otherwise standard New Keynesian model with capital, and study the determinacy and E-stability of Taylor-type interest rate rules. With very mild increasing returns supported by empirical research, the conventional wisdom regarding the design of...

We examine the expectational stability (E—stability) of rational expectations equilibrium under optimal interest rate rules in the context of the standard, “New Keynesian” model of the monetary transmission mechanism. We focus on the case where the monetary authority adds interest rate...

Based on database of ecological factors and geographic information space analysis method, we analyzed suitability of Wolfiporia extensa (Peck) Ginns producing regions, in the hope of providing reference for scientific zoning and cultivation. Ecological factors we analyzed mainly include...
