Replication Data for "Direct and Indirect Effects Based on Difference- in-Differences With an Application to Political Preferences Following the Vietnam Draft Lottery"

Data set from the “Young Men in High School and Beyond” (YESB) survey" for analyzing the impact of the Vietnam draft lottery on political preferences. It was used as empirical illustration for a difference-in-differences approach for disentangling a total treatment effect within specific subpopulations into a direct effect and an indirect effect operating through a binary mediating variable. The results suggest that a high draft risk due to the draft lottery outcome leads to an increase in mild preferences for the Republican Party, but has no effect on strong preferences foreither party. The increase in Republican support is mostly driven by the direct effect not operating through the mediator that is military service.
