Economies and diseconomies of scale pt2 Flashcards
Diseconomies of scale
In diseconomies of scale, the LRAC starts to rise with output as a firm expand
Reasons for diseconomies of scale-1
Poor communication in a large firm-hard to communicate ideas affecting staff morale, managers lose control, difficult to coordinate
Reasons for diseconomies of scale-2
More wastage and loss as firm grows-bigger warehouses means that things may go missing
What shifts LRAC?
External EoS shifts LRAC down as it reduces costs at all output levels
External DoS will force it to shift up
Returns to scale
Describes the effect on output of increasing all factor inputs
Shape of LRAC
The shape of the LRAC curve is due to returns to scale (RTS)
Shape of SRAC
The shape of the SRAC curve is due to diminishing returns
RTS graph
Increasing RTS=Economies of scale (decreasing costs)-Zone 1
Constant RTS=Constant costs-Zone 2
Decreasing RTS=Diseconomies of scale (increasing costs)-Zone 3
Zone 1
Increasing returns to scale means that an increase in all FoP leads to a more than proportional increase in output. E.G. Doubling factors leads to triple the amount of outputs. There is more output produced per unit of input
Zone 2
Constant returns to scale means that an increase in all FoP leads to a proportional increase in output. Doubling factors leads to a double amount of output. Costs increase proportionally to output
Zone 3
Decreasing returns to scale means that an increase in all FoP leads to a less than proportional increase. Tripling factors leads to a double amount of output, Less output produced per unit of input
