1.(15%) Two persons are involved in a situation where the public good, G, is privately provided. The utility function of each individual is denoted as ui(G,x) = ai InG + xi, for all i = 1,2 where x is a private good. Denote gi as the amount of the public good contributed by the individual i such that G = g1 +g2. Each individual's budget constraint is shown as xi + gi = my. Assume a1 ＜ a2. How much will the individual 1 contribute, i.e. g1, in equilibrium?
