This paper is based on the first chapter of my PhD dissertation at Wharton, and the author thanks advisors Andy Abel, Joao Gomes, Michael Roberts, and especially Urban Jermann for advice. The author thanks the editors and two referees for constructive feedback and conference discussants Nicholas Crouzet, Zhiguo He, Lei Mao, and Alessio Saretto and audiences at various venues for helpful comments. All errors are my own.
