Abstract

Within high-income countries, there is a notable income inequality spectrum, with certain nations positioned close to a predefined economic threshold, while others within this cohort simultaneously embark on substantial economic growth. This study investigates the influence of critical factors on economic growth and the transition from lower-high and middle-high income to upper-high income. Between 1990 and 2019, 25 of the 28 nations successfully advanced to upper-high income levels. Several key factors contribute to overcoming the barriers associated with lower-high income or middle-high income to upper-high income status. These factors include labor force participation, labor productivity, life expectancy, high-tech exports, reduction in unemployment rates, age dependency ratio, and poverty. The regression discontinuity analysis reveals a positive impact on the experimental group, as economic globalization surpasses the threshold of 78 % facilitating the achievement of upper-high income status.

探究高收入国家之间收入差异的原因

在高收入国家中，存在着明显的收入不平等现象，某些国家接近预定的经济门槛，而其他国家则同时实现了大幅经济增长。本研究探讨了关键因素对经济增长以及从中低收入向中高收入过渡的影响。从 1990 年到 2019 年，28 个国家中有 25 个成功晋升到高收入水平。有几个关键因素有助于克服与较低收入或中等高收入向高收入地位过渡有关的障碍。这些因素包括劳动力参与率、劳动生产率、预期寿命、高科技出口、失业率下降、受抚养人口年龄比和贫困。回归不连续分析表明，经济全球化超过 78%的临界值有助于实现高收入地位，这对实验组产生了积极影响。

期刊介绍： Established in 1947, Research in Economics is one of the oldest general-interest economics journals in the world and the main one among those based in Italy. The purpose of the journal is to select original theoretical and empirical articles that will have high impact on the debate in the social sciences; since 1947, it has published important research contributions on a wide range of topics. A summary of our editorial policy is this: the editors make a preliminary assessment of whether the results of a paper, if correct, are worth publishing. If so one of the associate editors reviews the paper: from the reviewer we expect to learn if the paper is understandable and coherent and - within reasonable bounds - the results are correct. We believe that long lags in publication and multiple demands for revision simply slow scientific progress. Our goal is to provide you a definitive answer within one month of submission. We give the editors one week to judge the overall contribution and if acceptable send your paper to an associate editor. We expect the associate editor to provide a more detailed evaluation within three weeks so that the editors can make a final decision before the month expires. In the (rare) case of a revision we allow four months and in the case of conditional acceptance we allow two months to submit the final version. In both cases we expect a cover letter explaining how you met the requirements. For conditional acceptance the editors will verify that the requirements were met. In the case of revision the original associate editor will do so. If the revision cannot be at least conditionally accepted it is rejected: there is no second revision.
