OperationId:research_pwt_country_iso3

Returns the country-year panel for one ISO 3166-1 alpha-3 coded country across all Penn World Table variables (or a caller-chosen subset). Annual cadence. Covers real GDP (expenditure and output side, both current and chained PPPs), national accounts, population, employment, human capital index, capital stock, TFP levels and growth rates, labor share, price levels, expenditure shares, and data-flag metadata. Not every country has full 1950 coverage - post-Soviet and post-Yugoslav states typically start around 1990-1992.
