We test implications of a simple equilibrium model of informality using a survey of 48,000 small firms in Brazil. In the model, agent's ability to manage production differ and informal firms face a higher cost of capital and limitation on size, although these informal firms avoid tax payments. As a result, informal firms are managed by less able entrepreneurs, are smaller and employ a lower capital-labor ratio. When education is an imperfect proxy for ability, the model predicts that the interaction of the manager's education and formality is positively correlated with firm size. Using the model, we estimate that informal firms in our dataset faced at least 1.3 times the cost of capital of formal firms.
