Exploiting 2019, 2020, and 2021 labor force survey data of the General Statistics Office to estimate the Mincerian wage model for waged workers in Vietnam, the results show that when controlling for different factors simultaneously, female workers have lower wages than their counterparts. Moreover, compared to before the pandemic (in 2019), the gender wage gap widened during the pandemic (in 2020 and 2021). Furthermore, results confirm social insurance's role in ensuring workers' income during the pandemic. Thus, the government must continue increasing social insurance coverage to ensure better protection for workers against risks occurring in the labor market.
