Theory of of Production Flashcards
What is production concerned with?
The nature of the conversion process, i.e., how inputs are converted into output
It involves the actual transformation of inputs into outputs or the creation of goods and services.
What does the production function show?
The relation between input changes and output changes
It also shows the maximum amount of output that can be obtained by the firm from a fixed quantity of resources.
What is the Law of Diminishing Returns (LDR)?
As more units of a variable input are added to fixed amounts of capital, the change in total output will first rise and then fall
What occurs when diminishing returns to labour happen?
Marginal product of labour starts to fall, meaning total output increases at a decreasing rate
What are the three stages of production?
- Stage of Increasing or Positive Returns
- Stage of Declining or Diminishing Returns
- Stage of Negative Returns
What characterizes Stage 1 of production?
Variable input is used with increasing output per unit, reaching a maximum at point B
In Stage 2 of production, what happens to output and physical products?
Output increases at a decreasing rate; average and marginal physical product both decline
What occurs in Stage 3 of production?
Too much variable input is used relative to fixed inputs, leading to a decline in output per unit of both fixed and variable inputs
In Stage 1, what is the relationship between average product (AP) and marginal product (MP)?
At this stage AP = MP
What is Total Product (TP)?
Measures the total productivity of variable inputs applied to a fixed input
Define Average Product (AP).
Measures output per worker employed or output per unit of capital
What is Marginal Physical Product of Labor (MPP)?
The change in output from increasing the number of workers used by one person or by adding one more machine to the production process
What is the Short-Run in production?
A time too short that can’t allow the firm to vary all its inputs; at least one factor of production is fixed
What are fixed inputs?
Inputs whose sizes do not vary with outputs, e.g., land, labor, capital, buildings
What are variable inputs?
Inputs that vary with outputs, e.g., raw materials, electricity, water
What is the Long-Run in production?
A time period long enough that allows the firm to vary all inputs used in the production process
What does the long-run allow a firm to do?
Choose those quantities of all factors of production that seem most suitable, including the option for a new factory
What is the expression for the production function?
X = f(a, b, c,…nth)
