The prospect theory is one of the most popular decision-making theories. It is based on the S-shaped utility function, unlike the von Neumann and Morgenstern (NM) theory, which is based on the concave utility function. The S-shape brings in mathematical challenges: simple extensions and...

We study the optimal output of a competitive firm under price uncertainty. Instead of assuming a risk-averse firm, we assume that the firm is regret-averse. We find that optimal output under uncertainty would be lower than under certainty. We also prove that optimal output could increase or...
