We consider preferences over risk and time, two fundamental concepts of economics. Our results provide striking evidence that there are good ...

We find that zero-mean and symmetrically distributed noise in the underlying parameters of these models can systematically distort choice probabilities, leading to false conclusions. Likewise...
