This paper examines the effects of the expansion of non-standard work arrangements on the distribution of wage income. Specifically, we quantitatively estimate the effects of the increased proportion of non-regular workers among wage earners on each income quantile and subsequent changes in Gini coefficient by using the Recentered Influence Function (Firpo et al., 2009). According to the analysis on 2014 survey on the working conditions, the increase in non-regular workers negatively influence income inequality in Korea. It turns out that the rise in non-standard work arrangement aggravates overall income inequality not only by lowering the wages of low-wage workers, but also by improving the wages of high-wage workers.
