b)Draw the world’d production possibility curve and if
the three countries find themselves in an open economy.
Graph the marginal cost of of producing cars in this
simple economy. Make sure to explain each graph.
2) Suppose a lake is publicly owned, i.e. a common property resource, with free fishing for all. The number of fish caught varies with the number of people fishing as follows:
Labour Total Product
1 13
2 25
3 36
4 46
5 55
6 63
7 70
8 76
9 81
Assume the market price of these fish is $10 per fish, and this price is not affected by the number of fish caught in this lake. Assume that all fishermen can earn $100 per day in their next best alternative. Assume the fishermen share equally in the proceeds of the lake.
a) Explain much fishing will occur ina common property setting i.e. how many people would join the fishery?
b) Assume now that the lake is privately owned and the owner hires fishermen for $100 per day. How much fishing would the owner allow i.e. how many people would join the fishery?
c) Why is the common property result considered to be inefficient?
Answer 1(a) :-
Canada = 6/20=0.33 units of clothing per car
Mexico = 15/20=0.75 units of clothing per car
U.S. = 30/30= 1 unit of clothing per car
Canada has a comparative advantage in producing cars .
Answer 1 (b) :-

Answer 2a :-
| Number of fishermen | Total fishes | Total Revenue | Public setting (per fishermen share ) | Private setting ( Profit earned) |
| 1 | 13 | 130 | 130 | 30 |
| 2 | 25 | 250 | 125 | 50 |
| 3 | 36 | 360 | 120 | 60 |
| 4 | 46 | 460 | 115 | 60 |
| 5 | 55 | 550 | 110 | 50 |
| 6 | 63 | 630 | 105 | 30 |
| 7 | 70 | 700 | 100 | 0 |
| 8 | 76 | 760 | 95 | (40) |
| 9 | 81 | 810 | 90 | (90) |
If the fishing occurs in a common property six fishermen will join fishing as after the seventh fisherman joins, the per person share reduces to dollar hundred which is the opportunity cost of the the fishermen that he could earnwhile working somewhere else. Therefore in a public setting and will join fishing.
Answer 2b :-
If the lake is on privately, then the the owner will hire 3 fisherman as after the fourth fisherman is being hired his total profit starts to reduce. Therefore the most optimal number of fishermen that should be hired by him to earn maximum profit of dollar sixty is 3 fisherman
Answer 2c :-
The the common property fishing is considered to be inefficient as as as the the extra profit earned by 6 fisherman after deducting the opportunity cost of Dollar hundred is $30 . while if the lake is owned by a private person then even after giving fisherman there share of dollar hundred the extra profit on his dollar 60 which is twice as compared to the common property setting.
Answer 3 :-
The steel tarrifs claim to protect 140000 workers however it does not take into account 6.5 million manufacturing workers whose job comes into to danger due to import tariff. As the US government has imposed 25% tariff on import of Steels. This has lead to Instant 25% price rise and the burden of this cost has been shifted to consumers by rising the prices of the goods . Thus the the cost of saving few workers has been largely imposed on a large amount of consumers consuming these products. Another threat is that these companies might shift to abroad where they can gain cheap materials, which will lead to lay off American workers and will work automatically in their disadvantage.
Answer 4a :-
Labour cost = $12000
Rent =$5000
Raw materials = $20000
Opportunity cost = 4000+15000)=$19000
Economic profit = 72000-56000=16000
Answer 4b :-
Total cost of producing 999 units = 999*1=$999
Total cost of producing 1000 units = 1000*1.1=$1010
Extra cost of producing 1 unit = 1010-999=$11
Revenue earned for extra unit =$5
Loss = 5-11=(6)
Thus the company should refrain from producing extra unit .
