d for the first one. Dunno, but the opportunity cost concept comes into play.

d for the first one

Why? I thought C, because I thought that is the level of normal profit so anything above that is abnormal/supernormal profit?

A firm earns supernormal profit when its profit is above that
a) earned by competing firms
b) needed to cover its fixedcosts
c) needed to keep the firm in production in the short run
d) required to keep its resources in their present use

d) A definition of normal profit is that which is required to keep the firm's resources in their present use.
Supernormal or abnormal profit is anything over and above that.
It's similar to transfer earnings and economic rent for an individual.

No, normal profit is for the Long Run. :smile:

Might be a) for the second one, higher natinoal income means higher demand for money, so LPC shifts right.

Ahh... silly me, normal profit recquired to stay in the industry in the long run! :mad:

Yes, it is a). I hate liquidity preference.... annoying topic.
As higher income, shouldn't you demand less money? Because you need less of a proportion of your income?

You get paid Friday, and gradually use the money to buy things, so there is an average money holding. If you start the week with a bigger wage, the average money holding/demand for money, is higher.

Sorry, it seemed hard that's all. But it's not,lol.

Just think the MC must cut the AVC at the minimum point on the AVC curve. It's straightforward now.

Reply 793

Yea, thats why I put the answer as increasing and increasing.
The answer scheme says increasing and decreasing. I don't understand how ATC can fall?? Doesn't it rise after the point where MC cuts AVC?

Reply 794

AVC must rise as you started at the minimum. ATC also rises, because it has reached a mimum already at a lower output. But I don't know why this happens. I'll let some else answer that.

thanks for the rep.

ATC = AVC +AFC, so if the fall in AFC exceeds the rise in AVC, ATC can fall.

Ignore this though, as if MC is rising then ATC must rise too, as far as I can see

Yeh, it does in the diagram I have. Maybe there is something else happening.
