Does Social Capital Sustain Trade Unions? Institutional Absorption and an Informative Null in 34 OECD-Area Countries

Data and Stata code reproducing every table and figure in the paper "Does Social Capital Sustain Trade Unions? Institutional Absorption and an Informative Null in 34 OECD-Area Countries". Balanced panel of 34 OECD-area countries, 2008–2019, N = 408, combining OECD/AIAS ICTWSS version 2.0 net trade union density with the social capital pillar and the interpersonal-trust element of the Legatum Prosperity Index (2023 edition), and World Bank World Development Indicators controls. Estimation covers a Mundlak decomposition, fixed effects with Driscoll–Kraay and country-clustered standard errors, Pesaran (2007) CIPS panel unit root tests, bootstrap Westerlund cointegration, and Machado–Santos Silva method-of-moments quantile regression. Contents: four Stata datasets, a single master do-file plus the same code in eight numbered stages, four figures, a build note documenting how the input panel was constructed from the two raw sources, and a README mapping every table and figure in the paper to the code that produces it. Software is Stata 19.5; required user-written commands are xtcd2, pescadf, xtwest, xtpedroni, xtscc, mmqreg, xtdolshm and wbopendata. File paths are relative, so Stata should be run with the code directory as the working directory. The ICTWSS source workbook is not redistributed here and is downloaded directly from the OECD at https://oe.cd/ictwss-20. The Legatum Prosperity Index workbook is likewise not redistributed; the extracted series appear in the deposited panel. Code is released under MIT and data under CC BY 4.0.
