IMPLICIT COST: An opportunity cost that does NOT involve a money payment or a market transaction. This should be contrasted with explicit cost that DOES involve a money payment or a market transaction. The common misconception among non-economists out there in the real world is that the term "cost" is synonymous with the term "payment," that is, all costs are explicit costs, to be a cost you have to give up some money. Well, I'm here to tell you that this isn't true. Cost is opportunity cost. It's the satisfaction NOT received from activities NOT pursued. It's the value of foregone production. And not all opportunity costs involve a money payment.
