So this question says that as a firm finds its profit is greater when it produces $40 dollars watts of product a.
00:13
So its profit is greater when it produces $40 watt of product a.
00:21
And suppose that each of three techniques shown in the following, the table we have, will produce a desired result.
00:31
Now the first question, with the resources price shown, which technique would the firm choose? why, the production using that technique until profit or loss? what would be the amount of that profit or loss? would the industry expand or contract? when will that expansion or contraction end? so to determine the total cost using each technique will multiply, the price per unit by the unit required for each resource multiply price per unit by unit required to get the total cost using each technique so for technique one from the table from for technique one three multiplied by five plus four multiplied by two plus 2 multiply by 2 plus 2 multiply by 4 is equal to 15 plus 8 plus 4 plus 8 and this is equal to 35 and this is 1 now for technique 2 we're going to have 3 multiplied by 2 plus 4 multiply by 4 plus 2 multiply by 4 plus 2 multiply by 4 plus 2 multiply by 4 plus 2 multiply by 4 plus 2 multiply by 4 plus 2 multiply by and this is 6 plus 16 plus 8 plus 4 and this is equal to 34 dollars so this is the second one now moving on for technique 3 we're gonna have 3 multiplied by 3 plus 4 multiply by 2 plus 2 multiply by 5 plus 2 multiplied by 4 and this is 9 plus 8 plus 10 plus 8 and this is equals 35 now the firm will choose going back to the techniques the firm will choose technique 2 because he has the lowest production cost and in the product is sold for 40 dollars and the only cost that's 4 dollars it will it will profit 6 dollar per unit so because it has the lowest production cost and if if it is sold for 40 dollars selling price and it costs and it costs 34 dollars to make then therefore the profit to be six dollar per units and this industry will expand because a profit will be made and the expansion will stop when the production will stop product is no longer profitable.
05:33
It will stop when the product is no longer available.
05:51
Now moving on to the second question, assume now that a new technique, technique 4 is developed and it combines two units of labor, two of land, you combine two units of labor, two units of land, and six units of capital, and three units of entrepreneurial ability.
06:53
Now, in the view of the resources price in the table, the firm adopts the new technique and explain your answers.
07:02
So a new technique that requires two units of labor, two units of land, six units of capital, and three needs of intrepidinary ability, the cost to produce the product with this new technique would be 3 multiplied by 2 plus 4 multiplied by 2 plus 2 multiplied by 6 plus 2 multiplied by 6 plus 2 plus 2 plus 2 plus 2.
07:41
So it costs $32 to produce and we can also that the production cost using this technique is even lower so the firm should adopt this new technique.
07:52
The firm should adopt this new technique.
08:23
So moving on, we have see.
08:38
Suppose that an increase in the labor supply causes the price of labor to fall to a dollar and 50 units, a dollar 50 per unit, all other resources, prices remain unchanged.
09:00
What technique would the producer now choose? explain so the labor cost has been reduced to a dollar and fifty per unit now the new production cost with each technique will now be recalculated so for technique one the production cost will be 1 .5 because of the 150 multiply by 5 plus 4 multiply by 2 plus 2 multiply by 2 plus 2 2 multiplied by 4 and this is 7 .55 plus 8 plus 4 plus 8 and this is equal to 27 .15...
