In the U.S. and a number of other countries, individuals wishing
to make organ donations at the end of their life have to “opt-in,”
i.e., to affirmatively agree to be a donor. In contrast, a host of
other countries have an “opt-out” policy, whereby you have to
explicitly state that you do not wish to be a donor to reject the
organ donation option. Can you use your knowledge of
behavioral economics to explain the empirical phenomenon that
organ donation rates are substantially higher in opt-out countries
than in opt-in countries?
