Pre-print, Working paper: We investigate the impact of different public transport pricing schemes on daily commuting habits. Psychological inertia, car stickiness, complexity aversion, or skewed perception of prices are expected to influence decisions. We build a controlled experiment, where participants make transport decisions and face various public transport tariffs. Our findings indicate that players are rational as they reach the Nash predictions of our model, but cognitive biases inherent to users are also present. Peak/offpeak and two-part tariffs prove to be more successful in encouraging public transit use than flat fare subscriptions, possibly due to a preference for flexibility and the ability to take past experiences into account (congestion and incident) in future travel choices. Thus, this paper suggests that well designed pricing strategies are useful tools to promote public transit use and reduce road congestion.
