We study asset prices and portfolio choice with overlapping generations, where the young disregard history to learn from own experience. Disregarding history implies less precise estimates of output growth, which in equilibrium leads the young to increase their investment in risky assets after...

We study an economy with a CEO who trades off the incentive to divert funds, which leads to underinvestment, against the incentive to overinvest based on his optimism. In equilibrium, we see overinvestment relative to what the shareholder or a social planner would implement but underinvestment...

We study how differences in beliefs about expected inflation affect the nominal term structure when investors have “catching up with the Joneses” preferences. In the model, “catching up with the Joneses” preferences help to match the level and slope of yields as well as the level of...

We show theoretically that inflation disagreement drives a wedge between real and nominal yields and raises their levels and volatilities. We demonstrate empirically that an inflation disagreement increase of one standard deviation raises real and nominal yields and their volatilities,...

We show that inflation disagreement, not just expected inflation, has an impact on nominal interest rates. In contrast to expected inflation, which mainly affects the wedge between real and nominal yields, inflation disagreement affects nominal yields predominantly through its impact on the real...

Correlations of equity securities have varied substantially over time and remain a source of continuing policy debate. This paper studies stock market correlations in an equilibrium model with heterogeneous risk aversion. In the model, preference heterogeneity causes countercyclical variations...

We investigate conditions for endogenous incompleteness and completeness in continuous-time financial markets driven by diffusion processes with multiple consumption goods and heterogeneous agents. We show that for a class of utility functions the financial market is endogenously incomplete. A...

With overlapping generations and heterogeneous risk aversion there is no unique relation between aggregate risk aversion and the real rate of interest, and this type of endogenous “noise” cannot arise in an economy where agents live forever. Our framework accommodates many agent types and...
