As of October 15, 2015, large stores (with 250 or more full-time employees) in England are required to charge shoppers 5 pence per new plastic bag. Plastic bags at airport shops or aboard trains, planes, and ships are not included, and neither are paper bags. An article in The Guardian indicated that the number of single-use plastic bags handed out by the seven largest supermarkets fell by more than \(85 \%\) in the first six months of the charge, more than \(£ 29\) million was raised for charities and community groups, and more people were bringing their own bags when shopping (Barkham, 2016). Does such a charge affect the marginal cost of any particular good? If so, by how much? Is this charge likely to affect the overall amount that consumers pay for the goods they buy?
