This article seeks to identify the different types of businesses (surviving firms, new firms, terminated firms) that contribute to the growth of labor productivity and total factor productivity (TFP) in the Moroccan manufacturing industry. We use two breakdown methods (Griliches and Regev, 1995; Foster, Haltiwanger, and Krizan, 2000) that allow us to take account of creative destruction (firm renewal) and the growth of surviving firms. We report three findings: (1) labor-productivity growth is heavily dependent on the growth of surviving firms; (2) inputs play a greater role in TFP growth, particularly by incorporating more efficient capital; (3) firm deaths explain the gap in employment growth between two sub-periods of the 1990s.
