Abstract

This paper presents an experimental study of common consequence effects in binary choice, willingness-to-pay elicitation, and willingness-to-accept elicitation. We find strong evidence in favor of the fanning out hypothesis for both WTP and WTA. In contrast, the choice data do not show a clear pattern of violations in the absence of certainty effects. Our results underline the relevance of differences between pricing and choice tasks, and their implications for models of decision making under risk.
