11- This question asks you to identify the efficient outcomes in a simple model with two individuals, Cathy and Vincent, and six outcomes, F, G, H, J, K, and M. Table below gives the level of utility obtained by each individual under each outcome. All six outcomes are feasible, and there are no other feasible outcomes. Which of the outcomes are efficient? Suppose a seventh option becomes available, and it provides utility levels of 206 for Cathy and 172 for Vincent. How would the set of efficient outcomes be affected? F G H I K M Cathy's payoff 0 60 200 100 40 205 Vincent's 170 60 65 40 110 95 payoff
