The U.S. system of securities law was designed more than 70 years ago to regain investors' trust after a major financial crisis. Today we face a similar problem. But while in the 1930s the prevailing perception was that investors had been defrauded by offerings of dubious quality securities, in the new millennium, investors' perception is that they have been defrauded by managers who are not accountable to anyone. For this reason, I propose a series of reforms that center around corporate governance, while shifting the focus from the protection of unsophisticated investors in the purchasing of new securities issues to the investment in mutual funds, pension funds, and other forms of asset management.

How much do cultural biases affect economic exchange? We answer this question by using data on bilateral trust between European countries. We document that this trust is affected not only by the characteristics of the country being trusted, but also by cultural aspects of the match between trusting country and trusted country, such as their history of conflicts and their religious, genetic, and somatic similarities. We then find that lower bilateral trust leads to less trade between two countries, less portfolio investment, and less direct investment, even after controlling for the characteristics of the two countries. This effect is stronger for goods that are more trust intensive. Our results suggest that perceptions rooted in culture are important (and generally omitted) determinants of economic exchange.

We study the location-specific component of research productivity for economics and finance faculty over the last three decades. We find that there was a positive effect of being affiliated with a top 25 university in the 1970s; this effect weakened in the 1980s and disappeared in the 1990s. The decline in elite university fixed effect is due to the reduced importance of physical access to productive research colleagues, which in turn seems due to innovations in communication technology. One implication is that knowledge-based organizations should find it more difficult to capture rents vis-à-vis workers. We find that faculty salaries increased the most where the estimated spillover dropped the most. Despite the loss in local spillovers, elite universities still enjoy an edge in average productivity because of agglomeration of top researchers in prestigious institutions with high long-term research reputations.
