Theory of production

1. What is the "production function" in economics?

• The process of distributing goods

• The relationship between inputs and outputs in production

• The total revenue generated by a firm

• The price elasticity of demand

2.The Law of Diminishing Marginal Returns states that:

• Adding more of a variable input increases total output at a decreasing rate

• Output increases proportionally with inputs

• Fixed inputs increase returns indefinitely

• Variable inputs lead to constant returns over time

3. 3. Which of the following represents a "fixed input"?

• Labor

• Raw materials

• Machinery

• Fuel

4. 4. In the long run, all inputs in production are:

• Fixed

• Variable

• Infinite

• Unchangeable

5. 5. The law of returns to scale is concerned with:

• Changes in output when one input is varied while others remain fixed

• Changes in output when all inputs are varied in the same proportion

• Changes in total cost as output increases

• Changes in revenue with respect to sales

6. 6. In the production function, "total product" refers to:

• The total number of inputs used

• The total output produced by the firm

• The total cost of production

• The marginal output from the last input

7. 7. Increasing Returns to Scale occurs when:

• Output increases more than proportionally to the increase in inputs

• Output decreases with an increase in inputs

• Output increases in the same proportion as inputs

• Output increases less than proportionally to the increase in inputs

8. 8. Constant Returns to Scale implies that if inputs are doubled, output will:

• Double

• More than double

• Less than double

• Remain the same

9. 9. In which stage of production does diminishing marginal returns set in?

• First stage

• Second stage

• Third stage

• Long-run stage

10. 10. Which of the following best defines "economies of scale"?

• The reduction in cost per unit as production increases

• The increase in output from additional inputs

• The increase in costs as production decreases

• The point at which marginal cost equals marginal revenue
