Consider the Minimum Effort Coordination Game, Where Players Choose Effort

Consider the minimum effort coordination game, where players choose effort levels of 1 through 7 with everyone choosing 7 being the payoff dominant outcome and everyone choosing 1 being the secure outcome. Suppose the cost of effort increases from 0.25 to 0.75. We would expect:

A) a. More players to choose 1 (or lower numbers in general) .
B) More players to choose 7 (or higher numbers in general) .
C) More coordination to the payoff-dominant outcome.
D) More groups to coordinate to outcomes in the middle such as 3, 4 or 5.
