Answer:
a) if the terms of trade are 4 chips for 1 pretzel, would trade be advantageous for Luxland? explain.
Yes, it is advantageous for Luxland. On its own, Luxland can only produce 1 chip for 1 pretzel, but with trade, 1 pretzel would now be equivalent to 4 chips, representing a net gain of 3 chips.
b) if the terms of trade are 4 chips for 1 pretzel, would trade be advantageous for Leanderland? explain.
No, trade would not be advantageous. We can see than domestically, Leanderland can produce 2 pretzels for every chip, because the graph shows that 4 chips are equivalent to 8 pretzels for this nation.
For trade to be advantageous, Leanderland should obtain at least 9 pretzels for the 4 chips.
