Knowing PED is important to Uber as it relies on knowing how elastic or inelastic demand is at different times and places so it can use dynamic (surge) pricing effectively. When demand in an area suddenly increases and passengers are less sensitive to price, Uber raises fares. This does two things: it increases revenue from riders who are willing to pay more, and it encourages more drivers to move to that area to meet the surge in demand.

Passengers who don’t want to pay the higher price can wait or choose another option, which helps balance supply and demand. Once enough drivers are available and demand becomes more price-sensitive again, Uber lowers prices back to normal. This is why understanding PED is essential to how Uber manages both profit and availability.

The UK government knows that the PED for vapes and tobacco is relatively inelastic amongst adults, who generally earn more, so it can raise the price via a tax and make a large amount of tax revenue. However, it is also aware that youngsters with lower incomes will have more elastic demand, as the % of their income is greater, so this may discourage them from continuing to consume these demerit goods before they become too heavily addicted.
