Globalization and the Decline in Labor Shares

We examine the empirical relationship between the institutions of economic freedom and labor shares in a panel of up to 93 countries covering 1970 through 2009. We find that a standard deviation increase in the Fraser Institute's Economic Freedom of the World (EFW) score is associated with about a 1/3 standard deviation increase in a country's labor share. Starting from the sample mean labor share in our panel, this amounts to about 4.26 percentage points. This relationship is robust to considering OECD and non-OECD samples separately. It is also (both qualitatively and quantitatively) robust to controlling for differences in human capital levels, labor productivity, trade union density, and international economic flows. We employ data from up to 125 countries during the 1970–2009 period to explore the relationship between globalization and labor share. Existing studies report a negative relationship between trade and investment flows and labor shares. While we also find that economic
