David Laibson

Economist whose name appears on both halves of this site's coverage: how choice environments help people, and how they are used to extract from them.
Who they are
Laibson works at Harvard on behavioural economics, self-control and household finance. He co-authored the shrouded attributes analysis and, separately, the active decisions work on pension enrolment.

Key ideas
Shrouding part of a price can be a stable market outcome where some consumers are inattentive.
Requiring an explicit choice, with no default at all, raised pension enrolment by twenty-eight percentage points against standard opt-in.
The same discipline produces both findings, which is worth noticing when either is quoted in isolation.
