$2.[15]$ Draw demand and supply curves for a good that is not private and use your graph to show that if the suppliers collude and all agree to charge a monopoly price higher than their marginal private cost, it might make the total surplus from the market $($for all the economy$)$ higher than if the suppliers acted perfectly competitively. Explain how this can occur. Is it possible that the buyers of the good in the market of part a also benefit from the collusion even though the output price is higher? If so$,$ show in a graph how it is possible. If not, justify your claim that it is not possible.
