A Guide to Duration, DV01, and Yield Curve Risk Transformations
Yield curve risk and sensitivities (DV01s) can be measured with respect to different variables: forward rates, par rates, zero yields, or others. This paper describes a simple method for transforming sensitivities between alternate representations and provides examples. The benefit of … Continue reading

A Dynamic Model of Labor Supply Under Uncertainty 1985
This paper lays out the model as in the 1981 paper but also discusses estimation and identification in some detail. Simplifies to a stationary environment with a single wage and then fits gross flow data. Includes empirical results showing interesting … Continue reading
A Dynamic Model of Labor Supply Under Uncertainty 1981
This paper lays out the theory of a three-state model of labor supply (job, unemployed, and out of the labor force) in full detail – stationary and non-stationary, discrete and continuous time. Proves existence and uniqueness of the value function. … Continue reading
