total cost function?
110.

112.
Refer to Figure 21.5. Economies of scale occur in the following range of factory sizes
113.

114. Which of the following is least likely to increase productivity?
115. Unit labor cost is equal to the
116. When the wage rate is $10 per hour and the MPP of a worker is 15 units per hour, the unit labor cost is
A. $0.67 per unit.
118. Assuming labor is a variable input, an increase in labor productivity will result in
119. Technological changes that increase productivity shift the
120. Higher education levels and better management
121. The creation of the World Wide Web has contributed to all of the following except
122. One In the News article titled "Funeral Giant Moves In on Small Rivals" reports that profit for a Houston-
based funeral giant is 31 cents on every dollar versus a profit of 12 cents for the funeral industry in general.
Such profits are most likely the result of
123. According to the World View article titled "United States Gains Cost Advantage," during the last decade,
unit labor costs in the United States declined
124. The World View article titled "United States Gains Cost Advantage" says productivity advances have
contributed to U.S. competitiveness in world markets. When improvements in productivity reduce costs, the
production function shifts
A. Upward and cost curves shift upward.
125. The In The News article "Ford Pumps $400 Million into Kansas City Plant" says that
126. Actual output will always equal the limit described in the production function.
127. The productivity of any input is independent and is not affected by the other resources that are used.
128. When a firm is able to achieve the output indicated by a production function, it is producing with
technical efficiency.
129. Short-run choices imply that at least one factor of production is fixed.
130. Total output may continue to rise even though marginal physical product is declining.
131. Marginal physical product is the change in total output associated with one additional unit of input.
132. Total output may continue to rise even though marginal physical product is negative.
133. The law of diminishing returns indicates that the marginal physical product of a variable input declines as more
of it is employed, ceteris paribus.
TRUE
134. Total revenue plus total cost equals profit.
135. Marginal cost always reflects the cost of variable factors.
136. If MPP declines with greater output, then MC must increase.
137. Total cost refers to the market value of all resources used in producing a good or service.
138. The total cost at a zero level of output is always equal to the variable cost.
139. When the marginal cost curve is below the average total cost curve, the average total cost curve must be
falling.
TRUE
140. The marginal cost curve intersects the minimum of the average total cost curve and also the minimum of the
average variable cost curve.
TRUE
141. The vertical distance between a firm's ATC and AVC curves grows smaller as output increases.
142. The difference between the accountant's and the economist's measurement of cost equals implicit costs.
143. There are still some fixed costs in the long run, such as rent.
144. In the long run, a company should choose the plant size that yields the lowest average total cost for the desired
rate of output.
145. The long-run ATC curve is simply a composite of the best short-run ATC possibilities.
146. If choosing a larger plant will reduce minimum average costs, there are economies of scale.
147. If a firm has constant returns to scale, the long-run cost curve will be downward-sloping.
148. Diseconomies of scale imply that the average total cost curve is downward-sloping in the long run.
149. More education and better technology contribute to an increase in productivity, ceteris paribus.
150. Unit labor cost represents the increase in output because an additional worker is hired.
151. If the MPP of a worker is 12 units per hour and the wage rate is $10 per hour, the unit labor cost is equal to
$1.20 per unit of output.
152. Better management shifts the production function downward and the total cost curve upward.
153. Economists point out that if it were not for diminishing returns, we could grow enough food to feed the world in a
flowerpot. Explain what they mean.
154. Explain the concepts of explicit costs and implicit costs. Why do economists include implicit costs in
their calculation of profits?
