RT info:eu-repo/semantics/article T1 Non-Constant Discounting and Ak-Type growth models A1 Cabo García, Francisco José A1 Martín Herrán, Guiomar A1 Martínez García, María Pilar AB This paper analyzes an Ak-type endogenous growth model under non-constant discounting,assuming both naïve and sophisticated consumers. For both type of consumersan isoelastic utility with an intertemporal elasticity below one guarantees observationalequivalence under exponential and non-constant discounting, but rejects strong equivalence(identical overall impatience does not leads to identical growth rates). Further,polices aimed at increasing productivity of the economy are less growth-enhancing thantypically predicted by the literature with exponential discounting.
