Okay, so for a, we're going to draw the lrac quantity and let me set it as cost.
00:13
So lrac would curve initially, or this curve initially decreases because of the economies of scale, but then increases because of these economies of scale.
00:28
And the weekly fixed fees would just shift the lrac curve upward uniformly.
00:39
So let me see here, like that.
01:01
Okay, so for b, you want to do a weekly demand curve and short -run industry supply curve.
01:15
Quantity and the price, and then we'll draw the demand curve here downward.
01:20
Downward and the short run supply curve.
01:24
So in the short run the industry supply curve would be the horizontal summation of individual firms marginal cost curves above their abc.
01:40
So let's say something like this supply and this is going to be our equilibrium q star and p star.
02:04
Okay, let me see and so this is where you sell q star and the long run equilibrium.
02:54
So here we have the economic profits of zero for each restaurant.
03:01
So price equals the minimum average cost, which is equal to minimum average cost.
03:22
See the impact of the macwandies deal? so okay, since you're the only mac 1d is in town, if are willing to pay more for branded burgers, the price of mac wendy's hamburgers might be higher than unbranded hamburgers.
03:43
But the price for non -branded hamburgers will remain unchanged.
03:59
Okay, just a moment.
04:48
Okay, so it looks like there is no graph in 4c...
