Use a domestic-market graph to: (a) show the effect of the export subsidy on the world price of solar panels, country A's domestic price, export quantity, consumer surplus, producer surplus, government expenditure, and total welfare; (b) Assuming that consumers are also taxpayers that pay for the government's subsidy expenditure in the above graph, identify the total change in consumer surplus due to the export subsidy.
