Slate reports on research by American economist Caitlin Kowles showing that women wait abot 20 seconds longer than men to be served at coffee shops. Check out the original paper here. Knowles has eliminated a few possible causes other than sexism - no surprise, it’s not because women order fancy drinks or flirt with the barristas.

Tyler Cowen, over on economics blog The Marginal Revolution suggests that women are more indecisive, but doesn’t really dispute Knowles’ main conclusion: “The simplest explanation, however, is that the staff feel more implicit psychological pressure to meet the needs of the male customers.”

Not a life-altering injustice, surely, but just another reminder that sexism lives in all of us, and intrudes on our lives almost constantly.

On the upside, it’s nice to see some feminist economics getting press coverage. I love feminist economics.
