Using data from the Vietnam Labor Force Survey, this paper takes a granular look at the most salient drivers of labor informality in Vietnam by examining: (i) the nature of labor informality and transitions from formal to informal employment status and the role of worker characteristics; (ii) the empirical likelihood of being in informal employment and the policy determinants of informality using within-in country variation in the business climate and governance; and (iii) whether different policy reforms have a differential impact on workers. Our analysis sheds light on how individual characteristics and policy impediments contribute to high levels of informality and points to the need for a comprehensive agenda to tackle informality.
