We would expect the number of sold plastic trash bag sales bags to increase, because as the summary points out, some people use the free bags as trash bags. However, I believe that simple comparison is incomplete. One of the environmental reasons for the ban was how the light-weight free bags get blown about and stuck in trees, clogs up the drains, etc., while the heavier-weight ones I could buy for 5 cents are more likely to be disposed of in an appropriate waste facility. This summary and what I can read of the paper don't touch on those other effects, which https://nextcity.org/urbanist-news/dallas-new-plastic-bag-fee-nickel https://nextcity.org/urbanist-news/dallas-new-plastic-bag-fe... implies were part of the reason for the short-lived ban, with: "In Dallas, the bag charge was a result of plastic bags’ toll on the environment and the general build-up of litter."
