近年来，人们越来越关注不平等对经济增长的影响。然而，理论论文和经验应用都产生了有争议的结果。虽然有相当一部分文献认为不平等不利于增长，但最近的研究对这一结果提出了质疑，并发现不平等对增长有积极影响。在本文中，我们提供了一个贡献的实证之谜，通过使用元分析系统地描述，识别和分析实证研究的结果的变化。我们发现，估计方法，数据质量和样本覆盖率系统地影响结果。研究结果指出，特别有用的是，应越来越多地将研究重点放在利用区域一级的单一国家数据或一组相对同质的国家数据确定收入不平等对经济增长的影响上，这些国家应充分控制经济、社会和体制特征方面的全国性差异。
In recent years there is a growing interest in determining the impact of inequality on economic growth. Theoretical papers as well as empirical applications have, however, produced controversial results. Although there is a considerable part of the literature that considers inequality detrimental to growth, more recent studies have challenged this result and found a positive effect of inequality on growth. In this paper, we provide a contribution to the empirical puzzle by using meta-analysis to systematically describe, identify and analyse the variation in outcomes of empirical studies. We find that estimation methods, data quality and sample coverage systematically affect the results. The results point out that it will be particularly useful to increasingly focus research on determining the impact of income inequality on economic growth using single-country data at the regional level, or a relatively homogeneous set of countries with adequate controls for country-wide differences in economic, social and institutional characteristics.
