There is a clear and persistent inequality of bureaucratic employment between individuals with a bureaucrat parent and those without. Using the recent anti-corruption campaign in China as a quasi-experiment, we investigate how endeavors for counter-corruption affect inequality and potential cronyism in bureaucratic employment through inter-generational transmission. First, we conduct a difference-in-differences analysis to compare changes in the probability of working in bureaucracy after the campaign came into effect in different provincial administrative divisions of mainland China, between individuals with a bureaucrat parent and those without. We find that before the campaign, bureaucrats' children were over 13 percentage points more likely to work in bureaucracy, and that positive selection on human capital can explain about one third of this advantage of bureaucrats' children. However, after the campaign took effect, this premium significantly reduced by more than 5 percentage points. Moreover, we explore potential mechanisms through which anti-corruption efforts have diminished the inter-generational transmission of bureaucratic employment. We provide evidence that the campaign decreased the economic attractiveness of bureaucratic jobs, and that better outside options are more likely to explain the reduced inter-generational transmission. We do not find evidence supporting other two alternative channels: the insider information of bureaucrat parents on the campaign, or changes in perceptions of bureaucracy.
