  1. Self-Image and Valuation of Moral Goods: Stated versus Real Willingness to Pay By Johansson-Stenman, Olof; Svedsäter, Henrik
  2. Brazilian 2010 presidential election: psychometric scaling of voting intention By Isabel Marques; Rodrigo Peñaloza

  1. By: Johansson-Stenman, Olof (Department of Economics, School of Business, Economics and Law, Göteborg University); Svedsäter, Henrik (Organisational Behaviour, London Business School, United Kingdom)
    Abstract: Hypothetical bias in stated-preference methods appears sometimes to be very large, and other times non-existent. This is here largely explained by a model where people derive utility from a positive self-image associated with morally commendable behavior. The results of a choice experiment are consistent with the predictions of this model; the hypothetical marginal willingness to pay (MWTP) for a moral good (contributions to a WWF project) is significantly higher than the corresponding real MWTP, whereas no hypothetical bias is present for an amoral good (a restaurant voucher). Moreover, both the theoretical model and the experimental evidence suggest that also the real MWTP for the moral good is biased upwards by being higher within than outside the experimental context.<p>

    Abstract: We apply the Thurstone method of unidimensional psychometric scaling to data sampled by CNI/IBOPE in three di¤erent periods before the Brazilian presidential election in 2010 regarding voting intention with respect to the main three candidates. Our results coincide with the overall rank of the candidates in each period and with the switch between the two main candidates in the last quarter before the election.
