We're given a table of production possibilities of product a to f for steel and wheat.
00:06
We're to find the total opportunity cost of the three units of steel, the marginal opportunity cost of the third unit of steel from c to d, and a change from combination c to b, and in moving stepwise from possibility a to b to c to f.
00:27
We're to find the cost of a unit of steel in terms of wheat and contrast how a market system and a command economy try to cope with economic staticity.
00:40
Firstly, to determine the total opportunity cost of the three units of steel, we need to compare the amount of wheat given up when producing each additional unit of steel.
00:50
So from a to b, the opportunity cost is 100 units minus 90, which is 10 units of wheat.
01:03
And from point b to c, the opportunity cost is 90 minus 75, which is 15 units.
01:12
From c to d, the opportunity cost is 75 minus 55, which is 20 units.
01:18
So the total opportunity cost for the three units of steel is 10 plus 15 plus 20, which is 45 units of wheat.
01:33
Now, for the second question, the marginal opportunity cost, this refers to the additional cost incurred when producing one more unit of a specific product.
01:48
So in this case, the marginal opportunity cost of a third unit of steel from c to d would be 20 units of wheat.
02:10
Now, this means that to produce one more unit of steel, 20 units of wheat must be given up.
02:17
Thirdly, a change from combination c to b means that there is a shift in production from two units of steel and 75 units of wheat to one unit of steel and 90 units of wheat.
02:39
So you can say there's a change or rather there's a shift in production from two units of steel and 75 units of wheat to one unit of steel and 90 units of wheat.
03:06
So this change indicates a decrease in the steel production clearly and an increase in the wheat production...
