information for Japan\u2019s House of Representatives elections held under the single nontransferable vote (SNTV) in multimember districts from 1958 to 1993. It draws on the Reed\u2013Smith Japan MMD data and linked reference sources, combining official election returns, candidate background codings, and census-based district demographics. Candidates include Liberal Democratic Party (LDP) nominees as well as LDP-related independents who commonly joined the party after election, reflecting the intraparty competition that characterized the SNTV era.\n\nEach record corresponds to a candidate in a given election and district, with identifiers for elections and districts, candidate attributes (age, gender, prior offices, bureaucratic career, secretary experience, hereditary or successor status), party information, and detailed election statistics (vote share, vote-share margin, counts of co-partisan candidates, incumbents, electorate size, valid votes, and turnout). Forward- and backward-looking indicators mark whether the same candidate (or a successor/heir) ran or won in adjacent elections. District demographics include population size and composition, urbanization (DID), and industrial structure, and year dummies tag specific election years. The file also contains flags related to redistricting and district magnitude, enabling analysts to study candidate performance and party competition across time and districts during Japan\u2019s pre-1994 electoral system.","file_sha256":"4779655b8f0ac7b0645e51f3f4b3d85985adaf80cda15d6c8112abb9bddb4144","frame_sha256":null,"role":"agent","transforms":[]}},"epoch":1,"event":"sample_init","question":"Among candidates at the win-loss margin, what is the average causal effect of holding office on the probability of running in the next election?","question_sha256":"ef29a35480088db5730ecab3c5d598aedf05775fba20cc5df9e92d51101a93ab","run_id":"20261015T171027Z-suite-crb_papers-naive-54c3f2","seq":0,"skills":[],"task_id":"crb_papers.q083","task_sha256":"277cd05b005b5ee27f6a81b19bbb0c5721199f04be015fbfa0d307bdf0ae6fd3","timestamp":"2026-10-15T17:10:29.691580Z"}
