All right, let's use this diagram to explain why each of the following statements is false for a competitive firm.
00:07
All right, so the first statement is that competitive firms will produce where price equals average variable cost.
00:13
All right, so this is wrong because, so let's draw a new curve on this graph we have.
00:17
So let's say that this is marginal benefit.
00:21
Right, so this is what's going to set the price.
00:25
Right, so right here will be our price if we set price equal to marginal cost.
00:32
Here is our price if we set it equal to a .v .c.
00:37
Right.
00:37
So the issue with setting it at average variable cost is that now marginal benefit is a lot less than marginal cost, right? so we could be producing less and be more efficient, right? so we, and over here, we have that marginal benefit would be greater than marginal cost, right? so we want to produce more.
00:59
So right here, we are actually going to set the price to be where marginal cost is.
01:09
And that's to make sure that marginal cost equals marginal benefit.
01:12
So we're having an efficient market.
01:14
All right.
01:14
So i'm going to reset our market here.
01:18
All right.
01:18
So our second question is that firm shut down when price is less than average total cost.
01:23
All right.
01:23
So this is false because although when price equals average total cost, oops, that should be a straight line.
01:31
When price is equal to average total cost, that means that we break even, right? so every additional unit that we get is equal to every additional costs.
01:40
So we're breaking even.
01:41
We're not making a profit or losing anything.
01:44
Right.
01:44
So let's say that it's less than average total cost, right? we are, although we're not making a profit, we're making a negative profit, we're still above our average variable cost, right? because one thing we have to keep in mind is our fixed cost.
01:57
No matter what, if we produce or not, we still have these fixed costs that we must pay, regardless of if we shut down or not...
