“…In a series of papers, Sachs and Warner (, , and ) find that there exists a strong negative relationship between a measure of natural resource abundance, share of primary exports in GDP and growth rate. This result is also confirmed by many following studies, like Gylfason, Herbertsson, and Zoega (), Gylfason (), Auty ( and ), Atkinson and Hamilton (), Papyrakis and Gerlagh ( and ), Neumayer (), Kronenberg (), Behbudi, Mamipour, and Karami (), Mavrotas, Murshed, and Torres (), James and Aadland (), Kim and Lin (). Additionally, an important study, Sala‐i‐Martin () describes this relationship as a robust one.…”
