econ questions聽日考T^T

聽日考T^T,THZ!

1)why income elasticity increases in LR decreases for durable goods in LR?our income will inc in LR?

2)

no supply curve for monopolists

why MR curve cannot represent?MR=MC->profit maximizing output

what is the difference between a MR curve and supply curve(a firm sell outputs at diff P)?

3)

MR=(delta PQ)/deltaQ=P+Q(deltaP)/(delta Q)

how to derive the statements below from this equation?

1,produce one more unit brings in extra revenue: P

2,with downward sloping demand,producing and selling one more unit results in small drop in price: (deltaP)/(delta Q)

reduction in revenue from all units sold: Q(deltaP)/(delta Q)

4)

P/MC=1/(1+1/Ed)=1+markup(in %)

=>markup =P/MC -1=(P-MC)/MC

But, i have asked my teacher what is the mark up in calculation before

she said P-MC

==>the underlined part is wrong?why?



5)

with a lower AC,it is more efficient to let it serve the entire market rather than have several firms compete in the market.Why?i dont understand@~@

6)perfect price discrimination
MR curve is the D curve =>no surplus
this means MR curve is the supply curve?why?

7)MRS=- deltay/deltax why there is a negative sign?

slope of budget line only=deltay/deltax

8)why diverify consumption is convex shape?
9)lumpsum cost of production inc=>inc MC,Ac COST SURVES?




Thanks!!!!!!!!!!
