abstract="Taking advantage of merged administrative data, we estimate the intended and unintended effects of two public policies aimed at combating driving under influence (DUI) of alcohol in Taiwan: the three-month-long campaign of random sobriety checkpoints in mid-2012, and the legal reform carried out in mid-2013 leading to much harsher punishments for DUI offenders. Our study gives rise to several important findings: (i) The checkpoint campaign substantially reduced DUI deaths and injuries, and the effect persisted after the campaign ended; (ii) the campaign also had a strong spillover effect of reducing non-DUI deaths and injuries, and this unintended effect was four times the size of the intended effect on DUI cases; (iii) these effects were not driven by social pressure or self-awareness arising from the intensive media coverage taking place at the same time; and (iv) there was little response to either policy among repeat DUI offenders and those who caused serious injuries.<p /> <p>Language: en</p>",
