Consider four cities, A, B, C, and D, located as follows: D Suppose that the residents of these cities consume widgets, with consumption in each city equaling 100 widgets (see the map below).

D
Suppose that the residents of these cities consume widgets, with consumption in each city equaling 100 widgets (see the map below). The
firm that produces widgets must deice how to arranges its production. It could set up four factories, one in each city, with each factory
producing 100 widgets. In this case, the firm incurs no cost for shipping its output. Or the firm could locate its factory in the centrally located
city, D. The single factory must then produce 400 widgets, 300 of which are shipped to cities A, B, and C. The shipping cost per widget is $2.
A final assumption is that widget production exhibits economies of scale, with the cost per widget production exhibits economies of scale, with
the cost per widget in a factory falling as output rises.
(a) Suppose that the cost per widget varies with output as follows: cost is $4 if factory output is 100 widgets; cost is $1 if factory output is
400 widgets. In this situation, find the bets arrangement of production for the firm (i.e., one central factory or four separate factories). THe best
arrangement leads to the lowest total cost for the firm, where the total cost is the sum of production and shipping cost.
(b) Repeat (a) if the cost per widget varies with output as follows: cost is $4 if factory output is 100 widgets; cost is $3 if factory output is 400
widgets.
(c) Explain intuitively any difference in the answers to (a) and (b).
(d) Suppose production costs are those given in (a), and let shipping cost per widget be given by t. Although t-2 in (a), what value oft would
make the two arrangements for production (centralized vs. separate factories) equivalent in terms of cost?
