Researchers who studied people who sell items on eBay (EBAY) turned up a surprising result: Women sellers get 80 cents on the dollar compared to men, according to a new study published in Science Magazine.
The researchers assessed over 1 million auctions from 2009 to 2012 and found that women sellers get fewer bids and lower final prices than men - for the same products.
The gender bias was greatest for new products.
In fact, it nearly disappeared for used items -- women make 97 cents for every dollar a man does.
The researchers said the lower gap seen with used products might be due to buyers unknowingly trusting women to give more accurate product descriptions.
The study, which looked at 429 of eBay's most popular items, found that even things like a seller's reputation score or the option to "buy it now" didn't mitigate the gender bias.
The gender bias was even apparent in the resale of gift cards of equal value, which are objectively the exact same item.
