Chia seeds are an agricultural good produced in many countries and priced in US dollars (US$).
Figure 1 illustrates the market for chia seeds in a small country called Nofiberland. D is the domestic demand and S is the domestic supply for chia seeds. Chia seeds can be initially imported at the current world price of US$15.00 per kg. Sw is therefore the world supply faced in Nofiberland with free trade. To protect Nofiberland producers, the government decides to impose a US$6.00 tariff on chia seed imports. St is therefore the world supply faced in Nofiberland after the tariff is imposed.
Figure 1
Calculate the total welfare loss resulting from the imposition of the tariff on chia seeds.
