Time delay, complexity and support for taxation

People often experience the benefits of taxation over time. We design an intertemporal market experiment with negative externalities to examine how delaying the benefits of taxation affects support for taxes. We find that when negative externalities occur immediately, people learn to adopt Pigouvian taxes, which are aimed at reducing negative externalities and restoring market efficiency. By contrast, when negative externalities are delayed, people are less receptive to taxation. This effect persists over time. Our data reveal that the strong negative delay effect can be explained in large part by narrow bracketing and the increased perceived complexity of the environment, rather than by time discounting per-se. We argue and demonstrate that increasing the transparency of intertemporal tradeoffs can effectively promote support for taxation.
