2012). In addition, Goodkind (1995) has identified four main factors to explain the reason why women in Vietnam often have low income. First, itis the influence of the war period before 1975 that undermined the positions of women in society, putting them in inferior job titles. Second, men's participation in war has made female workers redundant in the labor market, pushing their incomes down. Third, the commitment to policies of gender fairness in society pursued by Vietnam government are weakened during the 1980s. Moreover, confucianism and patriarchal monopoly in families tend to go up, and, as a result, women have to stand a lot of injustices in their life. Finally, due to a series of other policies and some historical factors, the desires to have sons, rather than daughters increased, leading to a decline in the position of women in society.Going deeper into the causes and factors affecting women's income in Vietnam, Liu (2004), using a data set of the private sector, showed that Vietnamese women are often underpaid because of their low levels of education, on average. Nguyen et al. (2011) used business data and showed that women in Vietnam often do not satisfy the high requirements in foreign-invested companies, who usually pay higher income for workers. As a result, women often decide to choose informal jobs or even unpaid housework.The above studies imply that although there are a number of studies about predictors of women income in both Asia and Vietnam, those studies do not systematically investigate the factors related to policy instruments, state institutions, women's gender roles and human capital that may affect women income. Besides, most studies in Vietnam use data of private sectors and companies, so there is a paucity of research that uses provincial data in Vietnam. This study utilizes data of 63 provinces in Vietnam for 5-year period from 2014 to 2018 to analyze factors influencing women income.
