Opportunity cost does not have to be measured in dollar terms. The value of an alternative activity is usually measured in both monetary and nonmonetary costs. Opportunity cost is referred to as implicit cost. Accountants count only explicit costs. Economic cost is higher than accounting costs because it includes implicit, or opportunity, cost.
