Note BAD : Why do some Firms abandon Formality for Informality? Evidence from African Countries

This paper analyzes the determinants of firms exiting the formal sector after registering at start-up. Using a unique and new dataset from four African countries (Cote d’Ivoire, Kenya, Nigeria and Senegal) with detailed information on firms that have transitioned between formal and informal status, we shed further light on the determinants of formality. We found that productivity and corruption (in terms of informal payments to public officials made by firms) significantly lead to firms going back into the informal sector even after initially registering at start-up. In the other direction, we found that higher productivity, better access to bank finance at start-up and education increase the likelihood of switching to formal status after initially being unregistered or informal at start-up. The results are robust to controlling for many relevant variables and controlling for selection.
