Three airlines (A, B, and C) are competing for passengers on a lucrative long-haul air route. At
present, the carriers are charging identical fares ($225 for a one-way ticket), the result of a truce
in recent price wars. The airlines currently compete for market share via the number of scheduled
daily departures they offer. Each airline must make a decision on its desired number of departures
for the coming month—without knowing its rivals’ plans ahead of time. Each airline is aware of
the following facts:


  1. The size of the total daily passenger market is stable regardless of the number of departures
    offered. At current prices, an estimated 2,000 passengers fly the route each day.

  2. Each airline’s share of these total passengers equals its share of the total flights offered by the
    three airlines. (For example, if airline A offers twice as many flights as each of its rivals, it claims
    half of all passengers and B and C obtain 25 percent shares.)

  3. The airlines fly identical planes and have identical operating costs. Each plane holds a maximum
    of 200 passengers. Regardless of the plane’s loading (full, half full, and so on), each one-way trip
    on the route costs the airline $20,000.


As the manager of one of these airlines, how many departures should you schedule for the coming
month? After seeing the first month’s results (your rivals’ choices and the resulting airline profits),
what decisions would you make for the second month and subsequent months?

CHAPTER 10 Game Theory and Competitive Strategy


It is a remarkable fact that business strategies are played largely in the mind.
Only a small part of the play appears in overt action. Its full scope and depth
lie in the players’ looking backward and forward and running through their
minds their alternative moves and countermoves.
