A Contribution to the Empirics of Total Factor Productivity’s Theory Based on a CES Production Function-Case of Moroccan Economy

This is the case for the estimation of total factor productivity based on the growth accounting’s approach which is easily verified with a Cobb-Douglas production function, but difficult to obtain with a CES production function. In this paper, we will try to do that estimation using Moroccan data.
