|March 2013||Bond Market Clienteles, the Yield Curve, and the Optimal Maturity Structure of Government Debt|
with Stéphane Guibaud, Dimitri Vayanos: w18922
We propose a clientele-based model of the yield curve and optimal maturity structure of government debt. Clienteles are generations of agents at different lifecycle stages in an overlapping-generations economy. An optimal maturity structure exists in the absence of distortionary taxes and induces efficient intergenerational risksharing. If agents are more risk-averse than log, then an increase in the long-horizon clientele raises the price and optimal supply of long-term bonds--effects that we also confirm empirically in a panel of OECD countries. Moreover, under the optimal maturity structure, catering to clienteles is limited and long-term bonds earn negative expected excess returns.

|May 2006||Intergenerational Risksharing and Equilibrium Asset Prices|
with John Y. Campbell: w12204
In the presence of overlapping generations, markets are incomplete because it is impossible to engage in risksharing trades with the unborn. In such an environment the government can use a social security system, with contingent taxes and benefits, to improve risksharing across generations. An interesting question is how the form of the social security system affects asset prices in equilibrium. In this paper we set up a simple model with two risky factors of production: human capital, owned by the young, and physical capital, owned by all older generations. We show that a social security system that optimally shares risks across generations exposes future generations to a share of the risk in physical capital returns. Such a system reduces precautionary saving and increases the risk-...
