Resumen

We consider the existence problem of errors in decision making processes under risk from a set-theoretical perspective. Choice adjustmenterrors have been identified but never formalized by the experimentaleconomics/decision theory literature. We show that choice adjustmenterrors can be naturally derived from gaps in the range of the utilityfunctions of decision makers. Introducing the concept of “error-inducedcertainty equivalent”, we account for the intrinsic generation of errorapproximations in any decision making process under risk. Finally, theexistence problem of minimal error functions is shown to be equivalent to that of determining best approximations to the expected utilityvalues defined by the corresponding decision processes.
