We develop a search and matching model where matches (jobs) can be formal or informal. Workers choose their level of schooling and search for an employee job either as unemployed or as self-employed. Firms post vacancies in each schooling market, decide the formality status of the job, and bargain with workers over wages. The resulting equilibrium size of the informal sector is an endogenous function of labor market and institutional characteristics. We estimate the model parameters using labor force survey data from Mexico and the exogenous variation induced by the roll-out of a non-contributory social program. Counterfactual experiments based on the estimated model show that eliminating informal jobs increases schooling investments but at the cost of decreasing welfare for both workers and firms.
