Income inequality, labor market inequality

The report published recently by the Paris School of Economics measures income and wealth inequality around the world and reveals the high share of total income accounted for by the top earners, reflecting a very worrying situation. The report notes that the top 1% of earners worldwide captured 27% of total income growth since 1980 (net of inflation), while the bottom 50% captured only 12% of income growth over the same period. The world’s reference points have definitely changed over this period. Individual country income-inequality trajectories are sometimes even more stark, but inequality in Europe has remained relatively stable since 1980.

Income distribution inequality raises a number of questions, particularly the challenge of achieving strong and sustainable growth. If growth only benefits a very small minority, then our aims cannot merely be restricted to growth at any price. The trickle-down theory whereby the poor derive benefits when the rich get richer is clearly not working, so it is vital to come up with different targets and mechanisms alongside growth to ensure a more balanced society.

On the US Income Distribution

A  national accounts framework  that can show the income distribution by decile is a priori  fascinating. Piketty, Saez and Zucman have done that for the US. It allows to look at income shares through time. They show that the first 5 déciles share in national income intersects this share of the top 1% in the 90’s. The first five déciles share went from circa 20% in the 70’s to a little more than 12% in 2014. The top 1% has had a profile that mirrored this trajectory from 11% to 20%. 

A comparison of the first five déciles share between the US and France shows that French people have had really a better situation.
