Term
Production means
Definition
Transforming productive inputs into products of greater value.
Term
Productive Inputs (Factors of Production)
Definition
Resources used to produce goods and services.
Term
Production Function (Description)
Definition
The maximum amount of output that can be produced with a given set of inputs.
Term
Production Function (Formula)
Definition
q = F(L, K)
Term
Fixed Input
Definition
An input that does not vary with the quantity produced
Term
Variable Input
Definition
An input that varies with the quantity produced.
Term
Short Run
Definition
The time horizon where some factors of production are fixed, and some are variable.
Term
Long Run
Definition
The time horizon where all factors of production are variable.
Term
Law of Diminishing Marginal Returns
Definition
With a fixed input, and an increasing variable input, at some point the marginal product of the variable input must decline.
Term
Opportunity cost
Definition
The next best alternative given up when making a choice.
Term
Sunk Cost
Definition
A cost incurred in the past that cannot be reversed.
Term
Fixed Costs
Definition
Costs that do not vary with the quantity of units produced.
Term
Variable Costs
Definition
Costs that vary with the quantity of units produced.
Term
Short Run Cost Function (Description)
Definition
The minimum possible cost of producing each level of output.
Term
Short Run Cost Function (Formula)
Definition
C = f(q)
Term
Average Cost
Definition
AC = C/q
Term
Average Variable Cost
Definition
AVC = VC/q
Term
Marginal Cost (MC) (Description)
Definition
The change in total cost attributable to the last unit produced
Term
Marginal Cost (MC) (Formula)
Definition
MC = dC/dq
Term
The range of Diseconomies of Scale
Definition
The range where long run average total costs increase as output increases.
Term
The range of Constant Returns to Scale
Definition
The range where long run average total costs remain constant as output increases.
Term
Optimal Firm Size
Definition
The quantity of production that minimizes long run average total costs.
Term
An Isoquant
Definition
A curve that shows all the input combinations that efficiently produce a given amount of output.
Term
Marginal Rate of Technical Substitution (MRTS)
Definition
The rate at which a producer can substitute between two inputs and maintain the same level of output.
Term
Marginal Rate of Technical Substitution for L with K (MRTSlk) (Description)
Definition
The number of units of capital a producer can give up in exchange for one unit of labor while maintaining the same level of output
Term
Marginal Rate of Technical Substitution (Formula)
Definition
-∆Y/∆x=MUx/MUy
Term
The concept of Returns to Scale
Definition
The effect that a proportional change in all inputs has on the level of output.
Term
The concept of Returns to Scale means
Definition
The effect that a proportional change in all inputs has on the level of output.
