收入不平等与石油资源诅咒
Income inequality and the oil resource curse
AI总结：
本文利用Standardized World Income Inequality Database和Heckman selection models，首次实证检验了石油依赖与收入不平等的关系及石油富国低报数据的偏差，发现除极度石油富足经济体外，石油与较低收入不平等相关。
摘要：
令人惊讶的是，关于石油依赖/丰裕度与收入不平等之间的跨国关系，目前几乎没有研究。同时，一些初步证据表明，石油资源丰富的国家倾向于低报收入不平等数据，这可能会影响石油丰裕度与收入不平等之间估计的经验关系。本文从两个方面为文献做出了贡献。首先，我们利用 Standardized World Income Inequality Database（标准化世界收入不平等数据库），深入探讨了石油与收入不平等之间的经验关系；这是关于收入不平等最全面的数据集，为最广泛的国家-年度观测值提供了可比数据。其次，据我们所知，这是首项采用经验框架来检验石油资源丰富国家是否倾向于低报收入不平等数据及其潜在影响的研究。我们利用 Heckman selection models（赫克曼选择模型）验证了石油富国低报数据的倾向，并纠正了可能由此产生的偏差；我们发现，除了极度石油富足的经济体外，石油与较低的收入不平等相关。
英文摘要：
Surprisingly, there has been little research conducted about the cross-country relationship between oil dependence/abundance and income inequality. At the same time, there is some tentative evidence suggesting that oil rich nations tend to under-report data on income inequality, which can potentially influence the estimated empirical relationships between oil richness and income inequality. In this paper we contribute to the literature in a twofold manner. First, we explore in depth the empirical relationship between oil and income inequality by making use of the Standardized World Income Inequality Database; the most comprehensive dataset on income inequality providing comparable data for the broadest set of country-year observations. Second, this is the first study to our knowledge that adopts an empirical framework to examine whether oil rich nations tend to under-report data on income inequality and the possible implications thereof. We make use of Heckman selection models to validate the tendency of oil rich countries to under-report and correct for the bias that might arise as a result of this; we find that oil is associated with lower income inequality with the exception of the very oil-rich economies.
