We study the optimal consumption and portfolio choice problem over an individual's life-cycle taking into account annuity risk at retirement. Optimally, the investor allocates wealth at retirement to nominal, inflation-linked, and variable annuities and conditions this choice on the state of the...

We study the economic importance of time-varying bond risk premia in a life-cycle consumption and portfolio-choice problem for an investor facing short-sales and borrowing constraints. On average, the investor is able to time bond markets only as of age~45. Tilts in the optimal asset allocation...

We study a dynamic asset allocation problem in which stock returns exhibit short-run momentum and long-run mean reversion. We develop a tractable continuous-time model that captures these two predictability features and derive the optimal investment strategy in closed-form. The model predicts...

A security's expected return can be decomposed into its "carry" and its expected price appreciation, where carry can be measured in advance without an asset pricing model. We find that carry predicts returns both in the cross section and time series for a variety of different asset classes that...

We propose a new way to construct instruments in a broad class of economic environments. In the economies we study, a few large firms, industries or countries account for an important share of economic activity. As the idiosyncratic shocks from these large players affect aggregate outcomes, they...

A large literature is concerned with measuring economic uncertainty and quantifying its impact on real decisions, such as investment, hiring, and R&D, and ultimately economic growth. The COVID-19 pandemic underscores the importance of timely measures of uncertainty and expected growth across...

We provide a theoretical and empirical analysis of the link between financial and real health care markets. This link is important as financial returns drive investment in medical research and development (R&D), which in turn, affects real spending growth. We document a "medical innovation...

We study the importance of time-varying bond risk premia in a consumption and portfolio-choice problem for a life-cycle investor facing short-sales and borrowing constraints. Tilts in the optimal asset allocation in response to changes in bond risk premia exhibit pronounced life-cycle patterns....

During the financial crisis, life insurers sold long-term insurance policies at firesale prices. In January 2009, the average markup, relative to actuarial value, was $-25$ percent for 30-year term annuities as well as life annuities and $-52$ percent for universal life insurance. This...
