“…The discussion was spurred by the finding of De Melo et al (1996) of a strong positive relationship in a cross section of 26 countries, with data covering the early 1990s.

While several studies replicated the finding of a positive impact of reform policies on growth, others found a weak or insignificant relationship.…”
