This paper analyzes the behavior of cross-country growth rates with respect to resource abundance and dependence. We reject the linear model that is commonly used in growth regressions in favor of a multiple-regime alternative. Using a formal sample-splitting method, we find that countries exhibit different behaviors with respect to natural resources depending on their initial level of development. In high-income countries, natural resources play only a minor role in explaining the differences in national growth rates. On the contrary, in low-income countries, abundance seems to be a blessing but dependence restricts growth.

资源诅咒的阈值回归

本文分析了跨国增长率在资源丰度和依赖性方面的行为。我们拒绝增长回归中常用的线性模型，而支持多机制替代方案。使用正式的样本分割方法，我们发现各国在自然资源方面表现出不同的行为，具体取决于其初始发展水平。在高收入国家，自然资源对解释国家增长率差异的作用很小。相反，在低收入国家，富足似乎是一件好事，但依赖限制了增长。
