Westward Magazine Publishers are thinking of launching a new fashion magazine for women in the under-25 age group.Their original plans were to launch in April of next year, but information has been received that a rival publisher is planning a similar magazine.Westward now have to decide whether to bring their launch forward to January of next year, though this would cost an additional $500,000.If the launch is brought forward it is estimated that the chances of launching before the rival are about 80%.However, if the launch is not brought forward it is thought that there is only a 30% chance of launching before the rival.

For simplicity, the management of Westward have assumed that the circulation of the magazine throughout its life will be either high or low.If Westward launch before the rival, it is thought that there is a 75% chance of a high circulation.However, if the rival launches first, this probability is estimated to be only 50%.

If the rival does launch first, then Westward could try to boost sales by increasing their level of advertising.This would cost an extra $200,000, but it is thought that it would increase the probability of a high circulation to 70%.This increased advertising expenditure would not be considered if Westward's magazine was launched first. Westward's accountants have estimated that a high circulation would generate a gross profit over the magazine's lifetime of $4million.A low circulation would bring a gross profit of about $1million.It is important to note, however, that these gross profits do NOT take into account additional expenditure caused by bringing the launch forward and/or by increased advertising.

1. Draw a Decision Tree to represent Westward's problem.
2. Assuming that Westward's objective is to maximize expected profit, determine the policy that they should choose.(For simplicity, you should ignore Westward's preference for money over time:For ex ample, the fact that they would prefer to receive a given cash inflow now rather than in the future.)
