The above paper (Shepherd and You 2020) was published with two errors. First, in attempting to provide a substantive interpretation of the primary coefficient in one of our analyses,wemade amistake on page 227. Given that our outcome variables are log-Transformed, a one standard deviation increase in the number of future lobbyist staff (0.34) is associated with 1.8% increase in a member's Legislative Effectiveness Score (LES) (exp(log(1.7)10.031730.34)21.750.0184), ifweevaluate the effect fromTable 2 at themeanlevel of LES. We mistakenly overstated the effect size by around 11 times. However, the corrected effect size is still substantiallymeaningful.Based on the coefficients of TableA.3 from theOnlineAppendix, which present the full regression results of Table 2, the effect of having an additional revolving-door staffer is about 19 th of the effect of switching tomajority party status on LES. This error does not affect the other analyses presented in the article and the corrected results do not change the main argument of the paper. Second,we reported results in Panel (B) ofTable 3without includingmember fixedeffects. In thetablebelow, we present the original Panel B in Table 3 (on the top) and the results with member-fixed effects included (on the bottom). Given that we already added a rich-set of member-level characteristics in our regression, adding member-FE does not significantly change the results.However, now theAdjustedR2 in PanelBcorresponds to the results in Panel A in Table 3. We regret both of these errors.
