The efficient operation and expansion of infrastructures in developing countries is crucial for growth and poverty reduction. However, recent reforms aimed at improving the performance of these sectors have had limited success. Evidence suggests that, in many instances, this was because the traditional regulatory theory relied on by policymakers was not suitable for the institutional context in developing countries. This article surveys more recent theoretical work focusing on problems with regulation in these countries. At the heart of the survey is the work of Jean-Jacques Laffont, who, in the last decade of his life, set about developing a theoretical framework for regulation in developing countries. We consider the implications of his work, which focused on the key institutional limitations faced in developing countries. We then discuss where experience suggests that there are important omissions from this modeling, bringing in extensions and alternative approaches pursued by other authors. We conclude by summarizing the key ways in which regulatory policy will be different when institutions are weak. Overall, we find that an understanding of the institutional context and its implications are crucial when designing a regulatory framework for developing countries.

This paper investigates whether interracial contact in childhood impacts adult romantic relationships. We exploit quasi-random variation in the share of black students across cohorts within US schools. We find that more black peers of the same gender lead whites to have more relationships with blacks as adults. While we do not find impacts on labor market outcomes, there are significant effects on reported racial attitudes. Furthermore, an increase in meeting opportunities is unlikely to explain the increased interracial relationships, since the effect is persistent across time, space, and social networks. Overall, interracial contact during childhood has important long-term behavioral consequences.
