My answers:

In monopoly the demand is inelastic because the monopolist can restrict output and/or rise price. There is less competition and also the MR = 0.

To answer your quetsion Lex:

If those elasticities are 1:

PES - 1 the supply line is going through the point of origin. This means it is UNITARY
PED = 1 = UNITARY. This means that if you raise or drop price then the revenue stays the same
.

If XED = 1: if price goes up by 10% then demand goes up/down by the same amount (you did not say -1 or + 1)

If YED = 1 then the income change and the change in demand are the same.

Now you tell me:

If the supply curve goes through the vertical then supply is elastic - why?

  1. Thanks for ur help....
    And about ur question....my answer is:Im an AS student and this is the A2 question(which means I don't know)....Kekekeke.....But I will still try to answer it:
    If the supply curve goes through the vertical then supply is elastic - why?
    Because the supply curve goes through the vertical ,so even the demand = 0 there's still supply,supply still exist...so the supply is elastic....Right...???Im not sure...

  2. And ye....one more question:
    1)What's the point of origin???
    2)If XED = 1: if price goes up by 10% then demand goes up/down by the same amount (you did not say -1 or + 1)
    XED=1:price goes up by 10% then demand goes UP by 10% right?Thanks again!

  3. The questions about elasticity is AS - we have done this in lessons!

    If XED = + 1 then they are....substitutes.

    1 and + 1 are the same
