| Abstract: | When rational risk-averse agents must choose among and share monetary risks, it is known that efficient sharing is typically nonlinear, even whit common beliefs. Wherever it is, the sharing rule may affect the choice, randomized choice may allow everyone to gain, and indeed a randomized choice between unacceptable risks may be acceptable. An important exception occurs if the agents' utility functions are all exponential, all logarithmic, or all the same power (HARA). |
