elections in the mid\u20112000s to early\u20112010s (covering multiple general and regional election cycles). The file merges administrative incident records (citizen reports filed with regional offices of the Attorney General), incident logs collected by the domestic observer Misi\u00f3n de Observaci\u00f3n Electoral (MOE), official polling\u2011station result files from the National Registrar (used to derive polling\u2011station size and rule\u2011based size measures), municipal demographic and fiscal indicators from administrative sources, and survey\u2011based individual measures where available (LAPOP). Variables include identifiers (department and municipality), election\u2011year indicators, several alternative and transformed measures of polling\u2011station and electorate size, presence/lagged indicators for nonstate armed actors and monitors, municipal socioeconomic controls (population, revenue and poverty measures), and multiple municipality\u2011level aggregates of reported electoral irregularities.\n\nThe released extract contains 4,352 municipality-year observations from elections in 2006, 2007, 2010, and 2011. The National Registrar sets voter-cap rules, and registered voters within a precinct are allocated to stations alphabetically. In the supplied construction, the cap is 400 in 2006 and 2007, 500 in 2010, and 350 in 2011. For potential electorate V and cap C, z_pob_mesa_f is V divided by (floor((V\u22121)/C)+1). Crossing a multiple of the cap adds a predicted station and lowers the predicted average size. Actual station arrangements can differ because of geography and special voting locations. The near-threshold subset flag is retained as supplied; it is separate from the full-file sample flag.\n","file_sha256":"5074479809b19d8b0940810ad65624efcd6d2593a1768c4c44406560c5ae6d69","frame_sha256":null,"role":"agent","transforms":[]},"ref_iv":{"description_shown":"","file_sha256":"5074479809b19d8b0940810ad65624efcd6d2593a1768c4c44406560c5ae6d69","frame_sha256":null,"role":"reference","transforms":[{"args":{"columns":["e_vote_buying","lm_pob_mesa","lpopulation","lpotencial","lz_pob_mesa_f","muni_code"]},"op":"select"},{"args":{"columns":["e_vote_buying","lm_pob_mesa","lpopulation","lpotencial","lz_pob_mesa_f","muni_code"]},"op":"dropna"}]}},"epoch":1,"event":"sample_init","question":"What is the local causal effect of a higher average polling-station size on municipalities' counts of citizens' reports of vote buying?
