The Wendy's restaurant chain will set Uber-style prices: its hamburgers will rise depending on demand. Wendy's CEO Kirk Tanner said a few weeks ago that the Dublin, Ohio-based chain will begin testing dynamic pricing next year.

A strategy that already works among app-based taxi companies - such as Uber or Cabify - and in the sale of tickets for events. The chain is the third largest hamburger chain in the United States, behind McDonald's and Burger King. Wendy's stock prices fell slightly in the morning session on Tuesday following the announcement.
