ItemProbing the Effect of the Australian System of Minimum Wages on the Gender Wage Gap(Melbourne Institute of Applied Economic and Social Research, 2017-12-04)When wage setting is more regulated, the gender wage gap tends to decrease. We examine whether this holds for a complex system of occupation- and industry-specific minimum wages, which cover both low-pay and high-pay segments of the labour market. The system has the potential to close the gender wage gap by ensuring equal minimum pay for equal jobs, but i also has the potential to widen it by discriminating against jobs more commonly held by women. We carefully describe wage levels as well as returns to experience and their association with individual gender as well as the male employment share in the individual’s field (industry or occupation) of work. We find that the gender wage gap among employees receiving a minimum wage is less than half the magnitude of the gap among other employees. Despite this, there is nonetheless evidence that, within the minimum-wage system, there is a wage penalty for employment in jobs more commonly held by women, although only for employees without university degrees. Our results suggest that, for university-educated women, the regulated setting of minimum wages helps to close the gender wage gap and counteracts the undervaluation of work typically undertaken by women. However, for less-educated women, who comprise approximately 82% of female minimum-wage employees, minimum wages could do more to close the gender wage gap if they were neutral with respect to the gender composition of jobs.

ItemWomen and Top Incomes in Australia(ANU Press, 2017)Tax, Social Policy and Gender presents new research on entrenched gender inequality in a comparative framework of human rights and fiscal sustainability. Ground-breaking empirical studies examine unequal returns to education for women and men, decision-making about child care by fathers and mothers, the history and gendered effects of the income tax and family payments, and women in the top 1 per cent. Contributors demonstrate how Australia’s tax, social security, child care, parental leave, education, work and retirement income policies intersect to compound gender inequality.

ItemSurvey Under-Coverage of Top Incomes and Estimation of Inequality: What Is the Role of the UK’s SPI Adjustment?(Melbourne Institute of Applied Economic and Social Research, 2017)Survey under-coverage of top incomes leads to bias in survey-based estimates of overall income inequality. Using income tax record data in combination with survey data is a potential approach to address the problem; we consider here the UK’s pioneering ‘SPI adjustment’ method that implements this idea. Since 1992, the principal income distribution series (reported annually in Households Below Average Income) has been based on household survey data in which the incomes of a small number of ‘very rich’ individuals are adjusted using information from ‘very rich’ individuals in personal income tax return data. We explain what the procedure involves, reveal the extent to which it addresses survey under-coverage of top incomes, and show how it affects estimates of overall income inequality. More generally, we assess whether the SPI adjustment is fit for purpose and consider whether variants of it could be employed by other countries.
