1. 1Preparação da base de dados
   ds_0079— | Variable Name | Description | | --- | --- | | Unnamed: 0 | Row identifier for the candidate observation (index carried over from the source CSV; not a substantive variable). | | d_board0 | Binary indicator equal to 1 if the individual ever served as a director on the board of at least one publicly traded corporation observed in BoardEx during 2000–2013, excluding any board positions held before the candidate’s first Senate election; 0 otherwise. | | margin | Vote margin in the candidate’s first U.S. Senate general election used for the dataset, measured as (candidate vote share − 0.50). Units are vote-share proportion (e.g., 0.03 = 3 percentage points above 50%; −0.03 = 3 points below 50%). | | everwon | Binary indicator equal to 1 if the candidate ever went on to hold U.S. Senate office at any point (i.e., ultimately won a Senate election and served), and 0 otherwise. This can differ from the first-election result captured by `margin` (e.g., a candidate with a negative first-election `margin` may later win and thus have `everwon = 1`). | Dataset Context: This dataset is a candidate-level file focused on U.S. Senate contests. Each row corresponds to an individual candidate, keyed to the candidate’s first Senate election used in the dataset, and includes (i) an election vote margin for that first contest and (ii) information on whether the individual later appeared as a director on the board of a publicly traded firm during the BoardEx coverage period. Corporate board service outcomes are based on BoardEx’s historical database of publicly traded firm directorships, which compiles board membership information from public disclosures for firms traded on U.S. exchanges. The BoardEx coverage window used here spans 2000–2013. Election results used to construct the vote margin were drawn from official election returns and standard political data sources. The board-service outcome variables are constructed to exclude board positions held prior to the candidate’s first Senate election. The dataset also applies eligibility restrictions consistent with the underlying data availability window (e.g., board outcomes are only observed in 2000–2013) and excludes cases where board service cannot be meaningfully assessed (such as candidates who did not survive into the relevant observation window or other similar sample restrictions implemented in the source study).
