  • Medicine low marginal health value

  • Idea: loved ones push, to show care

  • Theory approach

    • seek few assumptions explain much

    • evolutionary psychology

  • Non-obvious results inform policy


Rand health insure experiment

RAND Health Insure Experiment

  • 2000 families ‘74-’82, random vary copay

  • Free care (vs. pay) gave

    • MORE spending (25-30%), glasses, fillings, “restricted activity days,” appropriate visits

    • SAME deaths, general health index, physical functioning, physiologic measures, health practices, satisfaction, appropriate therapy

    • LESS blood pressure? (mortality: ~1% = 7wks)


Evolutionary psychology

Evolutionary Psychology

  • Our preferences, behavior adapted to hunter-gatherer environment

  • Illuminates mating, parenting …

    • eat too much fat, sugar, salt

    • women live longer than men

“I care, so keep me.”

“We care, so calm down.”


Predictions

Predictions

  • More care by insecure individuals with fewer other ways to signal.

  • Little effect of quality info unless commonly publicly accepted.

  • Spending increases not depend on technology, but on cohort changes.


Policy implications

Policy Implications

  • Need publicly accepted quality signals

  • Insure min/subsidy helps if signal risk, but hurts if signal concern

  • Need review all allegiance signals

    • care no longer reveals long-term
