An interesting new working paper tries to define whether economics departments are "saltwater" or "freshwater" based on citation networks. They find that the divide is strongest for macroeconomics and econometrics. This makes sense as this divide is about macroeconomics. So, this seems to be a real thing. It's amusing to see where non-US departments fall on the gradient. Looking at places I've studied or worked, ANU is saltwater and Hebrew University is freshwater, which is amusing (there isn't much water at all in Jerusalem and ANU is located next to a lake). LSE is very salty. More widely, Tel Aviv U. is very freshwater and Cambridge is very saltwater. By comparison, ANU and Hebrew U. are brackish. So it doesn't have anything to do with the water really :)
