4Adjusted Score
- Add expected returns to all teams cash
positions based on initial cost position - 407s costs were five standard deviations below
the mean in market B, which is worth about 1.6M - Only the best three cost positions in each
game-market are adjusted. Assumes 4000 units
sold in A and 2000 in B and D for top 3 players.
No adjustment for C. Why? - Does not account for the play of the game in
any way - Compare expected outcome to actual (in
millions) - Score (Expected Actual)10

24Lessons from the CSG
- Position matters but the play of the game is
often more important - Market attractiveness (market D) is not
sufficient to make profits - See 315
- Anticipating response how will my opponent play
and what should I do? - Average performance X1 1.8m, X2 1.2m, Z1
2.4, Z2 2.9 (medians are 1.85m, 2.25m, 2.1m,
2.55m)
25Lessons from the CSG
- Signaling is hard
- Very hard to enforce price discipline in markets
with multiple players - Z1 Market D 406 and 402 unable to coordinate on
follow the leader - The formal rules of the game matter
- Often called institutions
- Note how war of attrition may have worked for
some teams in a different context (but not this
one) - Everyone can play in differentiated markets, but
big producers compete against themselves
