Informal firms account for roughly one-third of production and one half to three-quarters of the non-agricultural labor force in developing countries and the informal sector is particularly important as a source of employment for the poor. However limited data and a focus on formal firms means relatively little is known about the productivity of these firms, the barriers they face for growth, and their spillover effects on the formal economy. This project therefore is conducting new surveys of informal firms, which can be used to study the dynamics of the informal sector, measure their interaction with the formal sector, and provide an empirical basis for modeling the aggregate growth effects. The initial phase of the research concentrates on informality among microenterprise firms. Panel surveys in Mexico and Sri Lanka have collected detailed information on the constraints facing microenterprises, their degree of interaction with the formal sector, and their motives for choosing informal entrepreneurship. Few microenterprise owners view the regulatory aspect of informality as being an obstacle to the growth of their business, with the majority seeing themselves as too small to benefit from registration. | Attitudes towards formalization among unregistered firms |

| Process of registration is too expensive Process of registering takes too much time The additional costs of operating as a regisered business are too high My business is too small I don't see the benefits of registering I do not know how to register No business like mine is registered Registration isn't ncessary Other | 2.0 8.2 4.1 75.5 6.1 6.1 6.1 2.0 8.2 | 2.0 6.4 2.9 52.0 7.7 8.0 12.5 - 6.1 | 
| The second phase of this work will collect detailed information on informality across the firm size distribution, allowing us to answer the following types of questions: - Are small firms constrained more by regulations, access to credit, or entrepreneurial talent?
Is there really a missing middle in the size distribution of firms, or do our surveys just not measure the middle well? Is the informal sector a breeding ground for formal sector entrepreneurs? How many medium and large firm owners got their start in the informal sector?
