Factors of Production-
|
Inputs or ingredients mixed together by a firm through its technology to produce output
Ex. Motion picture studio uses inputs such as producers, directors, actors, costumes, capital, sound stage etc. to produce movie |
Production Function
|
Relationship between inputs and outputs that identifies the maximum output that can be produced per time period by each specific combination of inputs
|
Q = f(L,K)
|
L- Labor K- Capital Q - Output
|
Technologically efficient-
|
Condition in which the firm produces the maximum output from any given combination of labor and capital inputs
|
Production function identifies...
|
Production function identifies hysical constraints with which the firm must deal
|
Assume the firm knows the production function for the good it produces and always uses this knowledge to...
|
Achieve maximum output from whatever combination of inputs it employs
|
Production when only one Input is Variable occurs in the-
|
Short Run
|
Fixed inputs-
|
Resources a firm cannot feasibly vary over the time period; costly to alter in a short time period
Ex. Commercial real estate developer unable to supply additional office space in response to increase in market demand |
Total Product-
|
The total output of the firm; varies as the firm employs different quantities of labor
|
Average Product-
|
The total output (or total product) divided by the amount of the input used to produce that output
Total product and thus average product of labor depends on the amount of other inputs (capital) being used- the amount of non labor inputs are held constant |
Marginal Product-
|
Represents the change in total output resulting from a one-unit change in the amount of the input, holding the quantitiesof other inputs constant
|
As long as marginal prodict is positive-
|
Total product wil rise; as long as an extra unit of labor produces some extra output (however small) total amount produced increases
|
When marginal product is negative...
|
Total product Falls
|
When marginal product is zero...
|
Total product is at its maximum
|
The rational producer will never operate where marginal product is negative because..
|
Employing a variable input at a level where Marginal Product is negative is technologically inefficent
* The firm can increase total product and lower production cost by using less of the variable input |
