The effects of banning advertising in junk food markets
| External publications
There have been calls for restrictions on junk food advertising to tackle rising rates of obesity around the world. This column examines the likely effect of a ban on potato crisp advertising. Results suggest that the total quantity of crisps sold would fall by around 15% in the presence of a ban, or by 10% if firms respond with price cuts. The welfare benefits from this would depend on whether current advertising is persuasive, informative or complementary.
