Tariffs and quotas (E.S. de Dios) 1. Suppose the market for a good in the absence of international trade (i.e., autarky) is described by the following functions of demand and supply: Q D = a bP (1) Q S = – c + dP . So that – as before – equilibrium price and quantity in autarky are given respectively by: P 0 = a + c b + d and Q 0 = ad - bc b + d . (2) 2. If there is international trade and the country is “small” relative to the rest of the world, it can import as much or as little as it needs at the world price P w without affecting that price. This implies that rather than P 0 , the world price P w (which is less than P 0 ) becomes the domestic price. It is easy to see that buyers will then demand the quantity Q D * = a bP w , (3) while sellers will produce Q S * = – c + dP w . (4) But where before quantity demanded equalled quantity supplied, now because price is lower, Q D * is greater than Q S * , and the difference is made up by imports. What will be the quantity of imports? The equilibrium quantity of imports M * is simply the difference between Q D * and Q S * , and this is obtained by subtracting (4)
