Opportunity CostOpportunity Cost Just like demand, supply and costs are also based
on valuations The cost of any action is the value of the
alternative opportunity that must be sacrificed in order to take the action.
Similarly manufactures must pay a resource a price that matches their best opportunity
There are no objective costs-cost is associated with action and choice

Non-Market SystemsNon-Market Systems
Any system to be efficient has to consider the alternatives for the resources being used
Without a market it is difficult to get that information and to use it correctly
Thus non-market systems frequently allocate resources incorrectly through central decision making
