An investigation of individual preferences: consistency across incentives and stability over time


Mentzakis, Emmanouil; Zhang, Jingjing (2012). An investigation of individual preferences: consistency across incentives and stability over time. Working paper series / Department of Economics 70, University of Zurich.

Abstract

This study compares individual preferences across incentives (i.e., hypothetical vs. real incentives) and over time (i.e. elicitation at two different points in time) in a choice experiment involving charitable donating decisions. We provide evidence of hypothetical bias but little evidence of instability of individual giving. There is significant heterogeneity in individual preferences, with real incentives either dampening or pronouncing the observed donating behaviour. Neither hypothetical bias nor instability is observed when we examine the propensity of individuals to make internally consistent decisions over identical choices.
