Abstract
This is a comparative empirical analysis of the effect of unemployment - via a ‘work-intensity effect’ and/or a ‘workplace-innovation effect’ - on manufacturing productivity growth in eight advanced capitalist economies. My econometric results confirm earlier findings of positive work-intensity and workplace-innovation effects of unemployment on productivity growth in the United States; but I do not obtain similarly strong results for the other countries, and in Germany and Sweden I find evidence of negative unemployment effects. My findings are consistent with the comparative hypothesis that the sign and strength of unemployment effects on productivity growth will vary negatively with the degree to which a country's socioeconomic environment is characterized by cooperative capital-labour relations and worker security.
