This paper studies the short-run and long-run behavior of a competitive economy in which both the discount factor and technological change are endogenously determined. In particular, the effect of saving behavior on persistent economic growth is considered. The paper provides the sufficient...

A challenge facing the literature of equilibrium indeterminacy and sunspot-driven business cycle fluctuations based on increasing returns to scale in production is that the required degree of increasing returns for generating indeterminacy can be implausibly large and rise quickly with the...

A challenge to models of equilibrium indeterminacy based on increasing returns is that required increasing returns for generating indeterminacy can be implausibly large and rise quickly with the relative risk aversion in labor. We show that unsynchronized wage adjustment via a relative wage...

This paper presents a small open economy version of the Benhabib and Farmer [2] two sector optimal growth model with production externalities. It is shown that indeterminacy is considerably easier to obtain under a regime of perfect world capital markets than in the closed economy variant....

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...

It has been shown that under perfect competition and constant returns-to-scale, a one-sector growth model may exhibit local indeterminacy when income tax rates are endogenously determined by a balanced-budget rule while government expendi- tures are fixed. This paper shows that the associated...

This paper makes use of optimal control relaxed problems to prove the absence of optimal trajectory in continuous time models with social increasing returns to scale where indeterminacy occurs. Although an efficient optimal policy does not exist, some chattering stabilization policies can mimic...
