Individual fixed effects No Yes No Yes No Yes

Notes: All regressions contain individual and state level controls, state, month, and year fixed effects, lead term, and state-specific linear time trend. Specifications 2, 4, and 6 add individual fixed effects. Standard errors, corrected for clustering at the state level, are reported in parentheses. The signs *, **, and *** denote statistical significance at 10, 5, and 1 percent significance level.
