(July 2008). Economic cost is the gains and losses in money, time and resources of one course of action compared to another. The comparison includes the gains and losses precluded by taking a course of action, as the those of the course taken itself.Economic cost differs from accounting cost because it includes opportunity cost.o for the two to four years an individual spends in school, the opportunity cost includes the money that one could have been making at the best possible job. The economic cost of college is the accounting cost plus the opportunity cost.
In a report, the U.S. Census Bureau estimated that nearly 7 million school-age children are routinely left home alone. âDevelopmentally, children are generally ready to be home alone around the age of 12 or 13,â says Cherie Sage, State Director of Safe Kids Kansas.
Here in Arizona, there is no law dictating the age at which a child is old enough to stay home alone, but that doesnât mean parents can leave children of any age to fend for themselves. A childâs readiness to stay home alone is dependent on many factors, most of which are very specific to that child.
