I've seen it happen at varying levels: Carrefour supermarket opened in my block next to a decades old famously local bakery/grocery store and undercut their prices by more than half, with a focus on infrastructure, quality and service, bakery went out of business, one year later all the prices in the supermarket were way up, staff was cut and service went terrible afterwards. There's a huge war on this with tons of delivery apps/ride sharing as well, in different corners of the world, Uber tried to burn cash to get ahead of taxis with coupons and discounts in several markets, it won in some, but lost big in China(Didi), India(Ola), and Indonesia(Grab). Another major example was the "Brazilian airbridge", the flights between SDU - CGH airports, when a growing company tried entering that market, three airlines bundled their offerings together to set prices and coordinate flight times, which priced their competitor out of the route, eventually getting them bankrupt.
