But those conditions are often not met, such as when production of the good creates negative externalities. If Farmer Ben produces apple cider and dumps his apple waste into the creek behind his barn, what negative externality might that create? Make up...

Tariffs never make small countries better off, but there are cases where they can make a large country better off. Draw side-by-side graphs for a good (call it “toothpicks”) where the small country can produce the good at a lower price than the large country. In this problem: SA : P =5 + 1.1Q DA : P =14 − 1.1Q SB : P =2 + 1.1Q DB : P =10 − 1.1Q Note that there is a worked example similar...
