We review experimental evidence collected from risky choice experiments using poor subjects in Ethiopia, India and Uganda. Using these data we estimate that just over 50% of our sample behaves in accordance with expected utility theory and that the rest subjectively weight probability according...

We present a new theory of decision under risk called third-generation prospect theory. A novel feature of our version of prospect theory is that, by allowing reference points to be uncertain, it is able to accommodate the phenomenon of preference reversal. While several previous theories of...
