The authors investigate the effect of an EU-wide consumer protection regulation on consumer trust as well as consumer behavior. The Unfair Commercial Practice Directive (UCPD) was implemented by EU member states between 2007 and 2010. They utilize data from the Special and Flash Eurobarometer for the years between 2006 and 2014 and experts’ evaluation on consumer protection levels before the introduction of the regulation. This rich data set allows to apply a difference-in-difference estimator with multiple time periods. The authors find a significant relationship between the introduction of the UCPD and consumer trust and cross-border purchases for countries with a low consumer protection level before the introduction of the UCPD. The relationship increases over time and stays then relatively constant.
