"Lessons from a feminist paradise on Equal Pay Day"

I've mentioned before that government-mandated maternity leave lowers women's wages, but what else does it do? Here are a few more examples comparing the US to other countries which have enacted more policies intended to improve the lives of women in the workforce:

In a 2012 report, the World Economic Forum found that when it comes to closing the gender gap in “economic participation and opportunity,” the United States is ahead of not only Sweden but also Finland, Denmark, the Netherlands, Iceland, Germany, and the United Kingdom. Sweden’s rank in the report can largely be explained by its political quota system. Though the United States has fewer women in the workforce (68 percent compared to Sweden’s 77 percent), American women who choose to be employed are far more likely to work full-time and to hold high-level jobs as managers or professionals. Compared to their European counterparts, they own more businesses, launch more start start-ups, and more often work in traditionally male fields. As for breaking the glass ceiling in business, American women are well in the lead, as the chart [in the article] shows.

What explains the American advantage? How can it be that societies like Sweden, where gender equity is relentlessly pursued and enforced, have fewer female managers, executives, professionals, and business owners than the laissez-faire United States? A new study by Cornell economists Francine Blau and Lawrence Kahn gives an explanation.

Generous parental leave policies and readily available part-time options have unintended consequences: instead of strengthening women’s attachment to the workplace, they appear to weaken it. ... According to Blau and Kahn, Swedish-style paternal leave policies and flex-time arrangements pose a second threat to women’s progress: they make employers wary of hiring women for full-time positions at all.

In which a cat has more publications to his name than some academics
"In 1975, Professor Jack H. Hetherington (Michigan State University) wrote a theoretical paper on his own and was about to send it to Physical Review Letters. But a colleague warned that the manuscript would be returned because of an editor’s rule that words like “we” and “our” should not be used in a publication with only one author. Dr. Hetherington did not relish revising and retyping the whole text, so, instead, he simply added a co-author: his Siamese cat Chester (sired by Willard)." You can find pointers to the cat's publications on Wikipedia.

Army Says No To More Tanks, But Congress Insists
"Yet in the case of the Abrams tank, there's a bipartisan push to spend an extra $436 million on a weapon the experts explicitly say is not needed. 'If we had our choice, we would use that money in a different way,' Gen. Ray Odierno, the Army's chief of staff, told The Associated Press this past week. Why are the tank dollars still flowing? Politics. Keeping the Abrams production line rolling protects businesses and good paying jobs in congressional districts where the tank's many suppliers are located."
Cousin Marriage and Democracy
"In the United States consanguineous marriage (marriage between close relatives, often cousins) is frowned upon and in many states banned but it is common elsewhere in the world. Approximately 0.2% of all marriages are consanguineous in the United States but in India 26.6% marriages are consanguineous, in Saudi Arabia the figure is 38.4% and in Niger, Pakistan and Sudan a majority of marriages are consanguineous." What are the health risks? "an elevated risk of birth defects but on the same order as a 40 year old woman having children as opposed to a 30 year old. In other words, the risks are small relative to other accepted risks."
