Abstract: |
We run a large-scale natural field experiment to evaluate alternative
strategies to enforce compliance with the law. The experiment varies the text
of mailings sent to potential evaders of TV license fees. We find a strong
alert effect of mailings, leading to a substantial increase in compliance.
Among different mailing conditions a legal threat that stresses a high
detection risk has a significant and highly robust deterrent effect. Neither
appealing to morals nor imparting information about others' behavior enhances
compliance. However, the information condition has a positive effect in
municipalities where evasion is believed to be common. Overall, the economic
model of crime performs remarkably well in explaining our data. |
