This survey investigates the inequality-fine wine imports nexus. To this end, the study employs cointegration techniques to analyze two panel datasets, one of which will analyze data from 12 countries between 1871 and 2018, and another that analyzes data from 66 countries between 1995 and 2017. Estimations indicate that income inequality leads to more fine wine imports in the long run. Changes in income have only a short-term effect on fine wine imports. Nonlinear autoregressive distributed lag (NARDL) estimators reveal an asymmetric long-run relationship between income inequality and fine wine imports in the cases of Argentina and the United States.

收入不平等和地位象征：优质葡萄酒进口案例

本次调查调查不平等——优质葡萄酒进口关系。为此，该研究采用协整技术分析两个面板数据集，其中一个将分析 1871 年至 2018 年间来自 12 个国家的数据，另一个将分析 1995 年至 2017 年间来自 66 个国家的数据。估计表明，收入不平等导致更多从长远来看，优质葡萄酒的进口。收入的变化对优质葡萄酒的进口只有短期影响。在阿根廷和美国的案例中，非线性自回归分布滞后 (NARDL) 估计量揭示了收入不平等与优质葡萄酒进口之间的不对称长期关系。（JEL 分类：C19、D01、D12、D31、L66）
