The usual conclusion in the literature is that sunspots reduce welfare because of the agents' risk aversion. However, if sunspots can lead to escape from an inferior steady state (poverty trap), this conclusion does not necessarily hold. Escaping trajectories can have much higher welfare than...

This paper studies the influence of different modelling assumptions on the determinacy of the steady state in one—sector models of economic growth with externalities in the production function. We show that productive public spending subject to congestion, combined with variable capital...

This paper contains a study of stochastic stability of the development trap in a model of economic growth when the production function is subject to externalities and, as a result, the development trap steady state ins indeterminate. In the presence of indeterminacy, sunspot equilibria can...

This paper considers the well known Romer model of endogenous technological change and its extension where different intermediate capital goods are complementary, introduced in (Benhabib, Perli, and Xie 1994). They have shown that this modification allows indeterminate steady state for...
