 My name is Matteo Wabba and I'm an assistant professor at the Toulouse School of Economics. I'm part of the development economics research group at the TSE and the group is fairly small in size but it covers a fair amount of countries that we study and also different topics that we consider. Industrial organizations in developing countries or the impacts or determinants of civil conflicts. In the recent paper of mine I consider the effects of informality. It is generally defined as the presence of a shadow economy in which both firms and workers do not declare themselves in the tax and government authorities. In this paper we consider one specific cost which is the potential disincentive for accumulating human capital. We find that the presence of informality creates frictions in the labor market that decrease the returns to schooling and by doing so it reduces the extent to which people acquire schooling in the first place. I foresee a potential methodological divide of my field with respect to other empirical fields in economics in terms of the empirical tools of investigation and in particular I envisage or probably desire for the next future is a higher extent or degree of blending of different methods empirical methods within the field to not confine development economics only into the realm of randomized control trials.
