1) Explain the relationship between total, marginal, and
average product.
2) Distinguish between fixed, variable and total
costs.
3) Explain the difference between average and marginal
costs.
b. Explain the relationship between total product, marginal
product, and average product. [3 marks]
c. What is the law of diminishing returns and what does it
explain the shape of the short run average cost curve. [3
marks]
d. Why is the level of output at which marginal revenue equals
marginal cost the profit maximizing output?
1. What is the relationship between marginal cost (MC) and
average total cost (ATC)?
2. What is the difference between positive and normative
statements? Which do economists generally consider the more
persuasive statement type, and why?
3. What are the conditions needed for the Supply and Demand
model to hold?
4. What is the difference between Quantity Demanded (Q_D) and
Demand (D)?
Plot the total, marginal, and average products and explain in
detail the relationship between each pair of curves. Explain why
marginal product first rises, then declines, and ultimately becomes
negative. What bearing does the law of diminishing returns have on
short-run costs? Be specific. “When marginal product is rising,
marginal cost is failing. And when marginal product is diminishing.
Marginal cost is rising.” Illustrate and explain graphically.
Define and explain the relationship between total revenue,
average revenue, and marginal revenue for a monopolist. What is
monopoly profit? Should a monopolist produce quantities of product
greater than that which would maximize profits?
Explain the relationship between elasticity, total revenue, and
marginal revenue. If you have a new product in the market, will you
set the product price in the elastic or inelastic area? Why?
