Our current social security system operates on a pay-as-you-go basis; benefits are paid almost entirely out of current revenues. As the ratio of retirees to taxpayers increases, concern about the high costs of providing benefits in a pay-as-you-go system has led economists to explore other...

We study mortgage design features aimed at stabilizing the macroeconomy. We model overlapping generations of mortgage borrowers and an infinitely lived risk-averse representative mortgage lender. Mortgages are priced using an equilibrium pricing kernel derived from the lender's endogenous...

We show that reaching for yield--a tendency to take more risk when the real interest rate declines while the risk premium remains constant--results from imposing a sustainable spending constraint on an otherwise standard infinitely lived investor with power utility. When the interest rate is...

This paper explores the effect of equity volatility on corporate bond yields. Panel data for the late 1990's show that idiosyncratic firm-level volatility can explain as much cross-sectional variation in yields as can credit ratings. This finding, together with the upward trend in idiosyncratic...

Goyal and Welch (2007) argue that the historical average excess stock return forecasts future excess stock returns better than regressions of excess returns on predictor variables. In this article, we show that many predictive regressions beat the historical average return, once weak...

To address the moral hazard problem that can motivate bank executives to take excessive risks and to fail to raise capital when needed, a group of 13 distinguished financial economists recommends that systemically important financial institutions be required to issue contingent convertible debt...
