Theory of Production and the Firm Flashcards
the study of how firms’ decisions about prices and quantities depend on market conditions
Industrial Organization
The goal of a firm
Maximize profit
total revenue (formula)
P x Q
Profit (formula)
TR - TC
require an outlay of money by the firm
Explicit Costs
do not require an outlay of money by the firm
Implicit Costs (ex: rent)
relationship between the quantity of inputs and quantity of outputs
production function
the increase in output that arises from an additional unit of input
marginal product
marginal product declines as the quantity of input increases
diminishing marginal product or law of diminishing returns
Does not depend on the quantity of output produced
fixed costs
A cost that changes as the firm alters the quantity of output produced
variable costs
total cost (formula)
FC + VC
Average total cost (formula)
TC / Q
an increase in total cost that arises from an extra unit of production
marginal cost
Three common features of cost curves
- MC rises with quantity output
- ATC is U-shaped
- MC crosses ATC at the minimum of average total cost
The efficient scale of the firm
the quantity that minimizes average total cost
When MC < ATC
ATC is falling (a good thing)
When MC > ATC
ATC is rising (bad)
When long-run ATC declines as output increases,
there are economies of scale
When long-run ATC rises as output increases
there are diseconomies of scale
the economies stock of equipment and structures
capital
inputs used to produce goods and services
factors of production
