Production Theory Quiz

What does an isoquant represent in production theory?

• Levels of profit for a firm

• Combinations of inputs producing the same level of output

• Cost minimization points

• Maximum utility for the consumer

What does the slope of an isoquant represent?

• Marginal product of labor

• The rate of technical substitution

• The opportunity cost of capital

• The break-even point

What is the main purpose of an isocost line?

• To show combinations of output levels

• To represent budget constraints for input costs

• To measure profit levels

• To maximize utility

If an isoquant is closer to the origin, it represents:

• Higher output levels

• Lower output levels

• A combination of higher costs

• None of the above

Isoquants that are convex to the origin imply:

• Increasing returns to scale

• Diminishing marginal rates of technical substitution

• Constant marginal product of inputs

• Decreasing returns to scale

The least-cost combination of inputs is achieved when:

• Marginal rate of substitution equals the ratio of input prices

• Marginal cost equals marginal revenue

• Total cost is minimized

• Profit is maximized

Which condition must be satisfied to achieve least-cost production?

• Marginal cost equals fixed cost

• Marginal product per dollar spent is equal across inputs

• Total revenue equals total cost

• Inputs are perfect substitutes

In a cost-minimizing input combination, if the wage rate increases, a firm will:

• Increase labor usage

• Decrease labor usage and substitute it with capital

• Maintain the same input mix

• Increase total costs

What happens when inputs are perfect substitutes in production?

• The isoquants will be convex to the origin

• The isoquants will be straight lines

• The isocost lines will become vertical

• There will be no least-cost combination

The law of diminishing returns applies when:

• Additional units of input lead to proportional increases in output

• Each additional input adds less output beyond a certain point

• Total cost increases with output

• Marginal revenue exceeds marginal cost
