Suppose the marginal cost curve in the short run first decreases, then reaches a minimum, and then increases. If we are at an output where marginal cost is increasing, then: Question 5 options: a) marginal product must be increasing. b) marginal product must be decreasing. c) average total cost must be increasing. d) average variable cost must be increasing.

b) Marginal product must be decreasing.

Explanation:

b) Marginal product must be decreasing.

The relationship between the marginal product and the marginal cost is negative which means if the marginal cost increases then the marginal product must fall. If the marginal cost decreases then the marginal product must increase. Therefore, option "b" that states marginal product decreases is the correct answer.

in 2001, dell computer became the world’s largest personal computer vendor, continuing to

gain market share and post profits in an industry struggling with slumping sales and billions of

dollars in losses. dell sells 90% of its pcs directly to the final customer, largely bypassing the

reseller channel that accounts for most of the world’s pc sales. this direct customer relationship

is the key to dell’s business model, and provides distinct advantages over the indirect sales

model. dell’s direct relationship with the customer allows it to tailor its offerings to customer

needs, offer add-on products and services, and use the internet to offer a variety of customer

services. in addition, dell’s pcs are built to customers’ specifications upon receipt of an order,

giving dell additional advantages over indirect pc vendors who must try to forecast demand and

ship products based on those forecasts. dell’s direct sales and build-to-order model has achieved

superior performance in the pc industry in terms of inventory turnover, reduced overhead, cash

conversion, and return on investment (kraemer, et al., 2000).
