There are two goods, both of which are characterized by internal returns to scale, and therefore consistent with intraindustrv trade. The values of imports and exports for the two goods are indicated in the table below. There are other goods in the background, so the value of total imports of these two goods need not equal the value of total exports. Calculate the GrubelLlovd index of intraindistrv trade for both goods. Imports Exports Cars 400 200 Vaccines 50 200 Be sure to provide explanations for vour answers and clearly show your calculations
