      abstract = {We measure the behavioural and motivational impacts of a  legislative change in England that required supermarkets to  charge for new plastic carrier bags they issued. Using a  difference-in-difference estimator, we find that the  treatment group used 1.7 less new plastic bags per shopping  trip after seven weeks. We also find evidence of  motivational 'crowding in'. That is, we find increased  motivation to reduce plastic bag use and acceptance of the  government's role in regulating their use. Using mediation  analysis we find that the price effect of the charge grows  over time, whereas the internal motivation effect falls (in  relative terms). Seven weeks after the legislation came  into force the price change explains 90% of the reduction  in new plastic bags used, while the change in motivation  explains only 10% of the reduction.},
