A field experiment in Sri Lanka provides informal firms incentives to formalize. Information about the registration process and reimbursement of direct costs does not increase registration. Payments equivalent to one-half to one month (alternatively, two months) of the median firm's profits leads to registration of around one-fifth (alternatively, one-half ) of firms. Land ownership issues are the most common reason for not registering. Follow-up surveys 15 to 31 months later show higher mean profits, but largely in a few firms that grew rapidly. We find little evidence for other changes in behavior, but formalized firms express more trust in the state. (JEL C93, D22, L25, L26, O14)
