Ideology and Revolution in Civil Wars: The “Marxist Paradox” –CORRIGENDUM

T he authors regret that they identified a missingness issue in a few variables in their dataset that capture state capacity, and which was due to an error in the merge code.After fixing this issue, the overall interpretation of the findings or the conclusions of the article remain unchanged.Specifically, the R merge code for the state capacity variables (04_merging_capacity_variables.R) contained errors leading to unnecessary NAs in the cross-sectional (final_cross.dta)and panel (final_panel.dta)final datasets for all the variables that were imported from the Hanson and Sigman (2021) (HS) (Capacity, Pre_ capacity, Post_capacity) and O'Reilly and Murphy (2022) (OM) datasets (Pre_sci_comp, Post_sci_comp).It also led to unnecessary NAs in the cross-sectional dataset (final_cross.dta)for the variable Sci_comp_diff, which is calculated as Post_sci_comp minus Pre_sci_ comp.The authors thank Ula Erdodu for letting them know about unnecessary missing cases in one of the variables, which helped identify the problem in the code.The authors have not identified any other errors in the imported state capacity data-only unnecessary missing values.To fix this problem, they hand coded the values of the HS and OM prewar capacity data in the cross-sectional dataset (Pre_capacity and Pre_sci_comp), and the value of the HS capacity data in the panel dataset (Capacity).They also hand coded the measures of postwar state capacity (Post_capacity and Post_sci_comp).These variables are used to calculate "state capacity difference" (Capacity_diff and Sci_comp_diff), a variable included in Table 7 of the main paper (and Table B.7 of the SM).They note that, for these variables, they have hand coded only the relevant cases for these analyses, which are wars that started before 1991 and did not end in rebel victory.The missingness issue impacted the following tables and figures in the paper and SM: Table 6 and Table 7 in the main article; Figure B.1, Table B.2, and Table B.7 in the SM.The rest of tables and figures in the article and
