Consider a two-hospital town with hospitals, A and B. The hospitals are considering installing a new imaging machine to attract more patients. The population of the town is small enough that it really only needs one of these machines. Purchasing a machine costs $1; 000. If both hospitals install a machine, each earns $800 in revenue. If only one hospital installs a machine, that hospital earns $1;800 in revenue. The other hospital loses $300 in revenue as patients switch to the other hospital. If neither hospital installs a machine, then revenue does not change for either one.
(a) Consider hospital Aís decision to buy one of these new machines. Aís proÖts will depend on what B decides to do. Suppose hospital B buys a machine. How much will A earn if it also decides to buy a machine? How much will A earn if it does not? What should A do if B buys a machine?
(b) Now considerAís optimal choice if B decides not to buy a machine. How much will A earn if it buys a machine? How much will A earn if it does not? What is Aís best response if B does not buy a machine?
(c) Hospitals A and B both act to maximize proÖts. What do you predict will happen in this market? Will the socially optimal outcome (only one machine is purchased in the town) happen?
(d) Suppose hospitals A and B shared an owner, who maximized joint proÖts rather than individual ones. What do you predict will happen?
(e) In this case, is hospital competition good for welfare? What other information, if any, would you need to make an assessment?
