Income Distribution and Aggregate Demand: A Global Post-Keynesian Model

The authors estimate the effects of a change in the wage share on growth at a national and global level in the G20 countries. They find that a decrease in the wage share leads to lower growth in the euro area, Germany, France, Italy, UK, US, Japan, Turkey, and Korea, whereas it stimulates growth in Canada, Australia, Argentina, Mexico, China, India, and South Africa. However, a simultaneous decline in the wage share in all these countries leads to a decline in global growth. Furthermore, Canada, Argentina, Mexico, and India also contract when they decrease their wage-share along with their trading partners.
