Denmark is getting rid of its “fat tax” imposed last year, as it has failed to solve the problem it was intended to address:
Gone, by popular demand: Denmark’s fat tax. ‘The fat tax is one of the most maligned we [have] had in a long time’, said Mette Gjerskov, the Danish food and agriculture minister, in a press conference on Saturday announcing the decision to ditch the policy. ‘Now we have to try improving the public health by other means.’
[. . .]
It turns out, unsurprisingly, that slapping taxes on things doesn’t necessarily persuade people to consume less of them. So Danes either went downmarket in their buying habits by buying cheaper products, or popped across the border to Sweden or Germany to buy their fatty foods there instead. The only real effect was to hit the profits of Danish companies. Chastened by the experience, the Danish government has also scrapped plans for a sugar tax, too.
As the OECD notes: ‘The impact of imposing taxes on the consumption of certain foods is determined by the responsiveness of consumers to price changes, ie, price elasticity. However, it is difficult to predict how consumers will react to price changes caused by taxation. Some may respond by reducing their consumption of healthy goods in order to pay for the more expensive unhealthy goods, thus defeating the purpose of the tax. Others may seek substitutes for the taxed products, which might be as unhealthy as those originally consumed. Depending on the elasticity of the demand for the taxed products, consumers will either end up bearing an extra financial burden, or changing the mix of products they consume in ways that can be difficult to identify.’
So, simply from a practical point of view, food taxes — indeed, any sin tax, including extra duty on tobacco or minimum prices for alcohol — can have some unwanted negative consequences while largely failing to achieve their intended aim.
