DESCRIPTION:In prospect theory (PT) the loss aversion index measures the si
 ze of the concave kink of the gain-loss utility function at the reference p
 oint. A truth-telling mechanism for assessing personal beliefs\, the quadra
 tic scoring rule\, is extended to measure loss aversion. We control for the
  bias captured by decision weights in PT and quantify efficiently with only
  three quadratic scores. In an experiment\, we demonstrate these features f
 or risk and extend the tool to ambiguity. We find median values of one at t
 he aggregate level for both sources of uncertainty. Probability and event w
 eighting are less pronounced but accord with earlier findings from the lite
 rature. These weights depend on the sign of the corresponding outcomes\, wh
 ich is implication of reference-dependent preferences. Event weighting is a
 lso observed at the individual level. After controlling for these weights\,
  we find very few subjects who are loss averse or gain seeking.\\n\\nContac
