January 2019Markets for Financial Innovation
with Kinda Cheryl Hachem: w25477
We propose a model where both security design and market structure are endogenously determined to explain why standardized securities are frequently traded in decentralized markets. We find that issuers offer debt contracts in thinner markets where investors have a higher price impact, and equity in deeper markets. In turn, investors accept to trade in thinner markets to elicit less variable securities from issuers if gains from trade are small. Otherwise, investors choose to trade in deeper markets where their price impact is minimized. We also show that there exist equilibrium market structures in which both debt and equity are traded.
July 2010Financial Connections and Systemic Risk
with Franklin Allen, Elena Carletti: w16177
We develop a model where institutions form connections through swaps of projects in order to diversify their individual risk. These connections lead to two different network structures. In a clustered network groups of financial institutions hold identical portfolios and default together. In an unclustered network defaults are more dispersed. With long term finance welfare is the same in both networks. In contrast, when short term finance is used, the network structure matters. Upon the arrival of a signal about banks' future defaults, investors update their expectations of bank solvency. If their expectations are low, they do not roll over the debt and there is systemic risk in that all institutions are early liquidated. We compare investors' rollover decisions and welfare in the two net...
