Discipline: Economics
Classical macroeconomic model is first developed by French economist Jean-Baptiste Say (1767-1832), and later revised by other classical economists.
Through the assumptions of factor and product price flexibility, and in the absence of regulations which prevent the market adjustment of demand and supply, full employment equilibrium will be reached in the classical macroeconomic model.
