Natural Resource Booms and Inequality: Theory and Evidence*
构建了一个两部门增长模型，解释资源丰富国家在自然资源繁荣后收入不平等的时间路径，并用90个国家1965-1999年的数据验证了理论，尤其适用于石油和矿产繁荣。
Abstract We develop a theory, in the context of a two‐sector growth model in which learning‐by‐doing drives growth, to explain the time path of income inequality following natural resource booms in resource‐rich countries. Under the condition of a relatively unskilled labor intensive non‐traded sector, inequality falls immediately after a boom, and then increases steadily over time until the initial impact of the boom disappears. Using data for 90 countries between 1965 and 1999, we find evidence in support of the theory, especially for oil and mineral booms. We also find that uncertainty about future commodity prices increases long‐run inequality.
