Growth effects of education and social capital in the OECD countries This paper surveys the empirical literature on the growth effects of education and social capital. The main focus is on the cross country evidence for the OECD countries but the paper also briefly reviews evidence from labour economics to clarify where empirical work on education using macro data may be relatively useful. It is argued that on balance the recent cross country evidence points to productivity benefits of education that are at least as large as those identified by labour economists. The paper also discusses the implications of this finding. Finally the paper reviews the emerging literature on the benefits of social capital. Since this literature is still in its early days policy conclusions are accordingly harder to find.
