Revenue Flashcards
TR calculation
P X Q
AR calculation
TR/Q
AR=P
why does AR = P
becuase TR - P*Q / Q = Q so Qs cancel out
Marginal Revenue meaning
extra revenue gained when we sell one more output
Marginal Revenue equation
change in TR / change in Q
Revenue depedns on
level of competition
what are the two types of competition
perfect
imperfect
state the conditions of perfect comp
many buyers and sellers( infinite (extreme))
homogenous goods and services
therefore
firms are price takers
No barriers to entry/exit
Perfect information about market condiitons
insane comp means firms are price takers what does this mean
regardles of number of units being sold
always sold at same price
AR and MR are
same and constant over range of ouptut
what are the axis on the perfect/imp comp rev groahs
y axis -price/revenue
x axis - quantity
Draw + describe how an AR and MR curve look
constant horizontal line
AR=MR=D
draw + describe+ explain how TR curve looks
linear upward sloping line
TR always increases by * so therefore linear upward sloping line shows constant gradient
i.e always increaseing by x
State assumptions of imperfect competiton
few buyers and sellers
all sell differentiated products
therefore
price makers
more brarriers to entry and exit
imperfect info of mkt conditions
How is the price set in imperfect competition
firms are price makers so charge diffrerent pries
