Popular wisdom holds that publishers revise college textbooks mainly to kill off the secondary market for used books. While this behavior might be profitable if consumers are myopic, uninformed or have high short-run discount rates (that exceed the publishers'), neoclassical authors have noted...

The viatical settlement industry provides an opportunity for terminally-ill consumers, typically HIV patients, to exploit a previously untapped source of equity in existing life insurance contracts to finance consumption and medical expenses. The 1996 introduction and dissemination of effecive...
