Women, if you’re selling something new on eBay, you’ll make more money if you get a male friend to sell it, according to a new study.

The findings, published Friday in the Journal Science Advances, revealed that on average, women make about 80 cents for every dollar a man does when selling the identical new product. The gender gap is much less acute on used goods, with women making 97 cents for every dollar on the same product sold by a man.

Using data supplied by the company, Tamar Kricheli-Katz, a sociologist and legal scholar from Tel Aviv University, and Tali Regev, an economist from the Interdisciplinary Center Herzliya analyzed US sales of the 420 most popular products from the full range of eBay categories between 2009 and 2012.

Women outsold men in certain categories, however, including baby products and toys for pets. Women also had higher “star” ratings, indicating better feedback from buyers.

Although Ebay doesn’t advertise a seller’s gender, the researchers say buyers can figure it out by looking at the seller’s username and the other products he or she is selling.
