Time Averaging Meets Labor Supplies of Heckman, Lochner, and Taber
We incorporate time-averaging into the canonical model of Heckman, Lochner, and Taber (1998) (HLT) to study retirement decisions, government policies, and their interaction with the aggregate labor supply elasticity. The HLT model forced all agents to retire at age 65, while our model allows them to choose career lengths. A benchmark social security system puts all of our workers at corner solutions of their career-length choice problems and lets our model reproduce HLT model outcomes. But alternative tax and social security arrangements dislodge some agents from those corners, bringing ...

Tracking Trend Inflation: Nonseasonally Adjusted Variants of the Median and Trimmed-Mean CPI
We make five contributions. We demonstrate that extant trimmed-mean and median CPI construction procedures depart from Bureau of Labor Statistics index construction procedures, and that the departures don't make much of a difference. We produce nonseasonally adjusted variants of the trimmed-mean CPI and median CPI, and demonstrate that these are useful real-time estimates of trend inflation; the NSA median CPI outperforms the median CPI, but both SA and NSA variants of the median and the trimmed-mean CPI easily dominate the so-called "core" CPI. We introduce superior ex post measures of trend ...

Time Averaging Meets Labor Supplies of Heckman, Lochner, and Taber
We add endogenous career lengths to the Heckman, Lochner, and Taber (1998a) (HLT) model with its credit markets and within-period labor supply indivisibilities, all of which are essential features of Ljungqvist and Sargent (2006) “time-averaging.” A benchmark social security system puts all workers at corner solutions of their retirement decisions. That lets our model reproduce most outcomes in HLT’s model with its inelastic labor supply and mandatory retirement date for all types of workers. Eight types of workers are indexed by pairs of innate abilities and choices of education ...
