Sample questions

1. In the context of the law of diminishing marginal returns, if the total product is increasing at a decreasing rate, what can be said about the marginal product?

   1. Marginal product is positive and increasing.
   2. Marginal product is positive and decreasing.
   3. Marginal product is negative and decreasing.
   4. Marginal product is zero.
   Show answer

   Answer: B. Marginal product is positive and decreasing.

   The law of diminishing marginal returns states that as more of a variable input is added to a fixed input, the marginal product of the variable input will eventually decline. When total product is increasing at a decreasing rate, it implies that each additional unit of input is contributing less to the total output than the previous unit, meaning the marginal product is positive but falling.

2. In the context of returns to scale, what does it mean if the isoquant map shows that to double output, a firm must more than double all its inputs?

   1. The firm is experiencing increasing returns to scale.
   2. The firm is experiencing constant returns to scale.
   3. The firm is experiencing decreasing returns to scale.
   4. The firm is operating in the short run.
   Show answer

   Answer: C. The firm is experiencing decreasing returns to scale.

   If doubling all inputs results in less than double the output, it signifies decreasing returns to scale. This means that as the scale of operation increases, the efficiency of combining inputs decreases, leading to a less than proportional increase in output.

3. Which of the following best describes Stage I of production?

   1. Marginal product is negative.
   2. Average product is at its maximum.
   3. Marginal product is positive and increasing.
   4. Total product is falling.
   Show answer

   Answer: C. Marginal product is positive and increasing.

   Stage I of production is characterized by increasing returns to the variable factor. This means that as more of the variable input is added, the marginal product increases, and consequently, the average product also increases.

4. The point at which the marginal product of labor (MPL) equals the average product of labor (APL) signifies:

   1. The end of Stage I of production.
   2. The beginning of Stage III of production.
   3. The point of maximum total product.
   4. The point of minimum average variable cost.
   Show answer

   Answer: A. The end of Stage I of production.

   The average product of labor is maximized when it is equal to the marginal product of labor. This intersection point marks the boundary between Stage I (increasing AP) and Stage II (decreasing AP) of production. It also represents the point of maximum average product.

5. When a firm is in Stage I of production, its average product is:

   1. Falling.
   2. Constant.
   3. Rising.
   4. Zero.
   Show answer

   Answer: C. Rising.

   Stage I of production is characterized by increasing returns to the variable factor. In this stage, both the marginal product and the average product of the variable input are rising.
