Under free trade, a large country produces one million leather bags per year and imports another two million bags per year at the world price of $60 per bag. Assume the country imposes a specific tariff of $5 per bag. As a result, the per-unit price of leather bags decreases to $58 in the international market and the import of leather bags drops to 1.6 million. The domestic production, on the other hand, increases to 1.1 million. Calculate the tariff revenue collected by the domestic government.
