Do Minimum Wage Increases Matter to Firm Profitability? The Case of Vietnam



This paper measures the impact of a minimum wage increase in 2005 on profitability of private firms in Vietnam using a difference-in-differences with propensity score matching method. Data used for this analysis are from Vietnam Enterprise Censuses in 2004 and 2006. It is found that the impact estimate of the minimum wage increase in 2005 from 290 to 350 thousand VND on firms’ profit margins is very small and negative and not statistically significant.
