The documentary series "Travail, salaire, profit" (work, salary, profit) takes us into the mysteries of the global economy, which is often too opaque to grasp all the ins and outs. GÃĐrard Mordillat and Bertrand RothÃĐ interview 21 researchers from around the world - economists, sociologists, historians, anthropologists, philosophers - on the fundamental concepts of the economy: work, employment, wages, capital, profit and the market.
