"As the role of mortgage brokers in mortgage origination grew from insignificant in the 1980s to dominant in recent years, questions have arisen about whether its services help or harm consumers. In response, states have increasingly regulated the business, largely by creating and tightening occupational licensing requirements for mortgage brokers. The question of whether increased occupational licensing of mortgage brokers improves consumer outcomes is theoretically ambiguous and has been little studied empirically. This study introduces a new database of mortgage broker licensing requirements and assesses the relationships between these requirements and outcomes in both the labor market for brokers and the consumer market for mortgages. We find that most aspects of mortgage broker licensing systems, such as mandatory professional education, do not have a significant and consistent statistical association with market outcomes. However, one component -- the requirement in many states that mortgage brokers maintain a surety bond or minimum net worth -- does have a significant and fairly consistent statistical relationship with both labor and consumer market outcomes. In particular, we find that tighter bonding/net worth requirements are associated with fewer brokers, fewer subprime mortgages, higher foreclosure rates, and a greater percentage of high-interest-rate mortgages. Although we do not provide a full causal interpretation of these results, we take seriously the possibility that restrictive bonding requirements for mortgage brokers have unintended negative consequences for many consumers. On balance, our results also seem to support theories of occupational licensing that stress the importance of pure entry and exit barriers over those that focus more on the human capital effects of licensing"--National Bureau of Economic Research web site.
