I'm not buying the article's premise, i.e. that pay is determined by productivity or its fascimile. As a counter-hypothesis, I offer the following: Men are selected / promoted / rewarded based on reliability, women on desirability. By reliability, I don't mean something mechanical such as defects per million, but closer in meaning to political reliability -- the tendency to adhere to norms and expectations. By desirability, I don't mean attractiveness, though that might form the largest component, but also availability (would she like me if our situation were a little different?)
