Firm Production, Costs, and Revenues Flashcards
Marginal Product (MP)
The additional output produced per period when one more unit of an input is added
Marginal Product Curve (MPC)
Shows the relationship between total product and labor
Law of Diminishing Marginal Returns
States that as the amount of one input is increased, all else equal, the incremental gains in output will eventually decrease
Average Product (AP)
(Total Product)/(Quantity of Input)
Total Product Curve (TPC)
Shows the relationship between the total amount of output produced and the number of units of a input used
Fixed Costs (FC)
Do not change when one more output is produced
Variable Costs (VC)
Change as more output is produced
Marginal Cost (MC)
The amount by which costs increase when one more unit of output is produced (MC = Change in TC/Change in Quantity = Change in TVC/Change in Quantity)
Average Total Cost (ATC)
TC/Q
Average Variable Cost
TVC/Q
Average Fixed Cost
Total Fixed Cost (TFC)/Q
Long Run and Short Run Difference
In the short run, the amount of at least one input cannot change
Economies of Scale
Exist over the range of output were the long-run average cost curve slopes downward
Diseconomies of Scale
Exist over the range of output where the LRAC is increasing
Increasing Returns To Scale
Exist when output increases (proportionally) more than increases in all inputs
Decreasing Returns To Scale
Exist when output increases (proportionally) less than increases in all inputs
Constant Returns To Scale
Exist when output increases in proportion to increases in all inputs
Diminishing Marginal Returns
Exist when an additional unit of an input increases total output by less than the previous unit of input
Increasing Cost Firm
A firm facing decreasing returns to scale
Decreasing Cost Firm
A firm facing increasing returns to scale
Increasing Cost Industry
Experiences increases in average production costs as industry output increases
Constant Cost Industry
Does not experience increases production costs as output grows
