Answer: x-inefficiency.
Explanation: Since it does not face any competition in its industry, the actions of Metropolitan Power and Light are an example of x-inefficiency which is a situation in which monopolies find themselves wherein they do not have to act efficiently since they are protected from competitive pressures. X-inefficiency is also applied to analyzing the average costs in imperfectly competitive markets whose average costs are higher than they would be if the market was more efficient.
