Some consumption opportunities are both indivisible and only valuable in particular tates of nature. The existence of such state-dependent indivisible consumption opportunities influences a person’s risk attitudes. In general, people are not risk averse anymore even if utility from divisible...

Some consumption opportunities, e.g. medical treatments, are both indivisible and only valuable in particular states of nature. The existence of such state-dependent indivisible consumption opportunities influences a person's risk attitudes. In general, people are not risk averse anymore even if...
