Nоte: Sаme infоrmаtiоn for questions 1-4. Two countries, A аnd B, share a border. Country A has five states: A0, A1, A2, A3, and A4. Country B has four states B1, B2, B3, and B4. The states were numbered in such a way that: Equally numbered states have the same GDP (GDP of state A1 = GDP of state B1, etc.). The distance between A0 and equally numbered states is about the same (the distance between A0 and A1 is about the same as the distance between A0 and B1, etc.). The following table shows distance in miles and total trade in millions of dollars, between A0 and the different states of each country. Use the gravity model to answer this question: Tradeij= A (GDPi GDPj) / Distanceij, where Tradeij is the trade volume between states i and j, A is a constant, GDPi is the GDP of state i, and Distanceij is the distance between state i and state j. Country A States Distance between Country A States and state A0 Trade between Country A States and state A0 Country B States Distance between Country B States and state A0 Trade between Country B States and state A0 A1 350 1388 B1 345 678 A2 350 1022 B2 345 481 A3 700 B3 673 A4 1567 544 B4 1593 233 Note that the distance between A0 and A3 is exactly double of the distance between A0 and A1. Suppose that the GDP of A3 is double of the GDP of A1, and that the GDP of A1 is double of the GDP of A0. Enter an estimate for the total trade between A0 and A3, in millions of dollars, or enter 0 if there is not enough information to estimate it.
