Biplab Ghosh recently defended his thesis under the advisorship of Prof. Dharmapala. His research interests lie in financial economics. His dissertation comprised three chapters, the first one tackles the theory that information asymmetry among investors leads to higher asset price volatility for firms. Testing this empirically, he finds that this is indeed the case, especially for small and illiquid firms, and those with a low book-to-market ratio. In the second chapter, he finds that higher firm level asset volatility leads to lower leverage. This can be viewed as a consequence of undiversified managers trying to reduce their own risk. And in the final chapter, he tries to explain the reason for the higher return of firms with high asymmetric information. It appears to originate with news about future cash flows rather than changes in the discount rate.
Ghosh will soon join Gustavus Adolphus College, a liberal arts college in Saint Peter, an hour from Minneapolis with about 2500 students. He will be teaching mostly finance courses in the College’s Department of Economics and Management.
