Overcoming Consumer Biases in the Choice of Pricing Schemes: A Lab Experiment

This paper uses experimental data to investigate possible biases in consumers' choice of pricing schemes when their demand is perfectly inelastic but uncertain. I consider threepart pricing schemes (i.e. fixed fee, included units, extra-unit price). The analysis suggests a strong bias towards the pricing scheme with the number of included units equal to the expected demand. I interpret this bias as an “anchoring effect” of the expected demand on consumer decisions. Interestingly, subjects invest less effort into the choice problem when the opportunity cost of a mistake is higher. Still, the higher opportunity cost of a mistake helps subjects overcome the bias.
