What do you mean by economic efficiency? It seems like the model of a lot of gig jobs encourages the employer to waste the worker's time.
This happens because the employer pays per job. For example, Bird and Lime waste workers time by letting them all chase after the same scooters to be charged so a worker might spend time going to pick-up a scooter only to be beat to it by another by a few moments. It seems highly suspect that this is the most efficient way to get this done unless your idea of efficiency only means lowest cost to the company.
