Dynamic pricing worked for Uber because it's a system where demand and supply can be influenced economically, leading to a surplus of trips and a big economic win.
Fast food like Wendy's operates in a non-stochastic system, making the effectiveness of dynamic pricing more limited compared to a system like Uber's.
Implementing dynamic pricing at Wendy's could help shape consumer behavior, improve operational efficiency, and line up customer demand with employee staffing, but may not have the same revolutionary impact as it did for Uber.
