Was the introduction of Uber Eats a Pareto improvement? Explain why or why not. You may wish to support your answer with a graph, but this is not required. If your answer is "no", explain whether it would be possible to design a way to introduce the Uber Eats service in a way that leaves everyone at least as well off (in terms of economic surplus) as they were before. (Note: You can be the "dictator" in this hypothetical, meaning that you can organise Uber Eats, allocate resources, direct payments, etc., however you see fit.)
