Time on PED (Short-Run)
In the short-run demand is price inelastic as there’s not enough time to search for substitutes. For example, if the train increases price by £2 you will still have to use it to go to school/work .
Time on PED (Long-Run)
In the long-run demand is price elastic as the consumer has had time to search for other substitutes. For example, if the train increased the price of a ticket by £2 last month- the consumer would of had time to switch to different means of transport e.g. bus.
