4. (32 points) Two mushroom hunters (Arslan and Barbara) go mushroom-hunting in the same wood (a common pool resource) and have the following utility functions, in which y is output (number of mushrooms obtained) and e is effort (time spent mushroom-hunting in the wood per day). Aslan's utility: uf = y4 - -(e4)2 (1) Barbara's utility: uB = yB 6 (e B) 2 (2) The number of mushrooms they catch (y) depends on their hunting effort (the number of hours spent mushroom-hunting per day), according to the following production functions: Arslan's catch: y = (1 -eB)ed Co Barbara's catch: y = (1 - e)eB (4)(d) Is the Nash Equilibrium of this game Pareto efficient?
