摘要

本文旨在利用 1989-2016 年期间意大利家庭财富调查(SHIW)的数据,分析有薪家庭和自营职业家庭的收入和消费不平等趋势,并研究总消费和收入不平等的变化在多大程度上可以用其长期和暂时组成部分的变化来解释。广义矩法(GMM)分析得出的结果显示,自雇家庭和工薪家庭在消费和收入不平等及其永久和暂时成分方面存在差异。特别是,自营职业家庭的收入和消费不平等程度都较高,总收入和消费不平等的增加主要是由其过渡性部分的增加所驱动的。此外,吉尼系数、对数方差、第 90/10 个百分位数和第 50/10 个百分位数等其他描述性不平等指标的研究结果也支持这样一种观点,即所有群体的收入不平等程度都高于消费不平等程度,而自营职业家庭的差异更为明显。

Income and consumption inequality trends: a comparative analysis between paid employees and the self-employed

Income and consumption inequality trends: a comparative analysis between paid employees and the self-employed

This paper aims to analyze trends in income and consumption inequality for paid and self-employed households and examine to what extent changes in aggregate consumption and income inequality can be explained by changes in their permanent and transitory components over time using data from the Italian Survey of Household Wealth (SHIW) covering the period 1989-2016. The results obtained from the Generalized Method of Moments (GMM) analysis reveal differences in consumption and income inequality, as well as their permanent and transitory components, between self-employed and payroll households. In particular, self-employed households experience higher levels of both income and consumption inequality, the increase in total income and consumption inequality is mainly driven by an increase in its transitory component. Furthermore, findings from other descriptive measures of inequality, such as the Gini coefficient, the variance of the log, 90th/10th, and 50th/10th percentile ratios, support the notion that income inequality is higher than consumption inequality across all groups, with self-employed households exhibiting a more pronounced difference.

期刊介绍: The Journal for Labour Market Research is a journal in the interdisciplinary field of labour market research. As of 2016 the Journal publishes Open Access. The journal follows international research standards and strives for international visibility. With its empirical and multidisciplinary orientation, the journal publishes papers in English language concerning the labour market, employment, education / training and careers. Papers dealing with country-specific labour market aspects are suitable if they adopt an innovative approach and address a topic of interest to a wider international audience. The journal is distinct from most others in the field, as it provides a platform for contributions from a broad range of academic disciplines. The editors encourage replication studies, as well as studies based on international comparisons. Accordingly, authors are expected to make their empirical data available to readers who might wish to replicate a published work on request. Submitted papers, who have passed a prescreening process by the editors, are generally reviewed by two peer reviewers, who remain anonymous for the author. In addition to the regular issues, special issues covering selected topics are published at least once a year. As of April 2015 the Journal for Labour Market Research has a "No Revisions" option for submissions (see ‘Instructions for Authors’).
