The study looked at how wages and productivity are related in Ghana. They used data on workers and their companies to see how different factors affect both wages and productivity. Here are the main findings: 1) Women get paid less than men, but they are just as productive. 2) As workers gain more experience, their wages and productivity go up, but at a slower rate over time. 3) More education and training lead to higher wages and better productivity. 4) Workers with different levels of education have different productivity levels, with a bigger gap than in wages. 5) Education pays off for everyone, but less so for unskilled workers. 6) Training from outside sources boosts wages but doesn't immediately improve productivity. 7) Union members earn more and are more productive than non-union members.
