The present contribution tests whether countries can be pooled when studying the finance-growth nexus. Overall, our results point toward a 'pragmatic' positive answer, though considerable heterogeneity is present among developing countries.

In this paper we adopt both a nonparametric and a semi-parametric IV estimator to show that the relationship between inflation and output growth is non-linear and that there exists a threshold level below which inflation has no effects on growth.
