Firm size and mobility: descriptive evidence from the Senegalese formal sector, 2008-2020

Since 2008, the 10% largest firms in Senegal have consistently accounted for 90% of the total revenue of the private formal sector. These firms are also more profitable on average, and much more likely to maintain their relative position than other firms are to move up the distribution. Further research should attempt to explore the role of such dominance on market distortions.
