The paper shows that financial market equilibria need not exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. The reason is an infiniteshort-selling problem. But even when a short-sell constraint is added, non-existence can occur due to...

We observe that the standard variant of Prospect Theory cannot describe very risk-averse choices in simple lotteries. This makes it diffcult to accommodate it with experimental data. Using an exponential value function can solve this problem and allows to cover the whole spectrum of risk-averse...

Prospect theory has found an increasing attention in many fields of economics. However, it has scarcely been addressed in a macroeconomic growth model. In an earlier paper we introduced prospect theory into a stochastic growth model. This paper focuses on linking the Euler equation induced by...
