Quizplus · Accepted Answer

Export supply is the quantity of a good or service that a nation is willing and able to sell to foreign buyers at a given price. In the given data, Q_s represents the domestic quantity supplied and Q_d represents domestic quantity demanded. Therefore, Alpha's export supply would be the difference between the domestic quantity supplied and domestic quantity demanded, which is shown as (Q_s - Q_d) in the data. In choice A, the expression (Q_d - Q_s) represents Alpha's export demand, which is not the same as export supply. In choice C, the expression (Q_d + Q_s) represents the total quantity of the good in Alpha, which is not relevant to determining export supply. In choice D, the expression (Q_s / Q_d) represents the price elasticity of supply, which is not relevant to determining export supply. Therefore, choice B is the correct answer as it represents the difference between the domestic quantity supplied and domestic quantity demanded, which is Alpha's export supply.
