Inflation, Race, and Legislation—The Erosion in the Real Value of Monetary Compensation for Miners' Occupational Lung Disease in South Africa, 1973–2024

open access: yesAmerican Journal of Industrial Medicine, EarlyView.
ABSTRACT Background For much of the 20th century, the South African mining industry had a statutory compensation system for pneumoconiosis and tuberculosis characterized by gross racial inequality. This study examines the impact of inflation over the period 1973–2024 on the real value of miners' lung disease compensation, including the effect of the ...
