IT’S EQUAL PAY DAY: When you hear that women are paid 79 cents on the dollar, remember that while the comparison is between full-time workers, what constitutes full-time work varies. Full-time men work longer hours than full-time women.

• A few years back, when Dr. Diana Furchtgott-Roth compared 40 hours workers to 40 hours workers, she found women make 86% of what men make.
• When she compared 35 to 39 hour a week workers, she found women made 107% of what men make (yes, women made more).

It’s complicated. And this is only one of the complications.
