Fixed effect predictions from all demand models from the alcohol purchase task used in Kaplan et al. (2021). Y-axis is number of drinks purchased; x-axis is log10 price per drink. All model predictions were transformed to represent raw consumption values rather than scaled predictions to allow for plotting to group data. The size of the data points are representative of the number of participants that purchased that number of drinks at a given price. Larger circles indicate higher frequencies. Y-axis is compressed from 11 to 50 but included to illustrate consumption occurring at higher values. Circles touching the y-axis (i.e., left-most circles) represent consumption at 0 cost. Because values of 0 cannot be plotted on a logarithmic scale, models predicted to 0.0000001 for plotting purposes. The break in the x-axis is meant to approximate price as it approaches 0 to demonstrate predicted consumption near 0. X values left of break span from 0.0000001 to 0.15.
