Identifying income heterogeneity determinants using the method of moments quantile regression

Prior studies have typically concentrated on poverty status to determine anti-poverty measures; however, this approach cannot sufficiently detect income heterogeneity. This study employs quantile regression for panel data to investigate the Korean Labour and Income Panel Study 2003–2020. Moreover, it adopts both household- and community-level variables and separates demographic groups as working-age and older adults, considering Korea's severe old-age poverty. The findings indicate that household-level characteristics, such as householder's gender, physical health, and employment status, present heterogeneous effects across the income distribution. Second, low-income households are more vulnerable to regional economic and labour market downturns than high-income neighbours. Lastly, although the National Pension, a backbone of the public pension system, provides limited supports for retirees because it was introduced much later than other countries, it assists low-income old adults more effectively. Therefore, this study suggests more tailored redistribution measures, considering heterogeneous effects of household- and community-level environments, and a further expansion of the National Pension to mitigate old-age poverty.     

风险投资驱动企业“脱虚向实”了吗

近年来，企业金融化现象在学术界备受关注。国内外研究表明，风险投资对企业投资和企业创新均具有积极影响，那么风险投资能否影响企业金融投资行为？以2009—2019年沪深两市首次公开发行的A股上市公司为研究样本，实证分析风险投资对企业金融化的影响。结果表明：风险投资对企业金融化具有显著抑制作用，且这种抑制作用存在异质性。具体而言，风险投资对企业金融化的抑制效应主要体现在制造企业、盈利能力较弱企业、非国有企业以及东部区域企业中。同时，机构投资者持股比例越高，风险投资对企业金融化的抑制作用越强。机制分析结果表明，风险投资通过促进企业实体投资抑制企业金融化。进一步分析发现，风险投资能够缓解被投企业融资约束，而融资约束的改善并未促进企业金融化，而是促进企业创新。结论可丰富风险投资与企业金融化相关领域研究，证明风险投资能够驱动实体企业“脱虚向实”，对政府发展多层次资本市场，引导金融回归实体具有一定的参考价值。
