Data for: Four-decision tests for stochastic dominance, with an application to environmental psychophysics

Dataset used in the paper "Four-decision tests for stochastic dominance, with an application to environmental psychophysics" by Angel G. Angelov, Magnus Ekström, Bengt Kriström, & Mats E. Nilsson. The data are from an experiment where participants were asked about their willingness to pay for an improved residential sound environment (traffic noise reduction). Each participant was requested to answer by means of: (i) a self-selected point (SSP), i.e., the amount in Swedish kronor he/she would be willing to pay per month for the improvement, and (ii) a self-selected interval (SSI), i.e., the lowest and highest amounts he/she would be willing to pay. Description of the variables and some remarks are given in a separate file.
