The determinants of income inequality in OECD countries
研究了1990-2013年25个高收入OECD国家收入不平等加剧的原因，发现金融化、劳动力灵活性增强、工会力量削弱和福利国家紧缩是主要驱动因素。
The objective of this paper is to identify the determinants of the increase in income inequality that OECD countries have experienced over the past two decades. My hypothesis is that along with the financialisation of economies that has taken place since 1990, inequality increased because labour flexibility intensified, labour market institutions weakened as trade unions lost power, and public social spending started to retrench and did not compensate for the vulnerabilities created by the globalisation process. Using data from 25 high-income OECD countries from 1990 to 2013, I empirically evaluate this hypothesis. My results clearly suggest that the increase in inequality over the past two decades is caused by an increase in financialisation, a deepening of labour flexibility, the weakening of trade unions and the retrenchment of the welfare state.
