> The bridging of sociology, history and economics was somewhat rare back in the 80s and before. (Douglas North a notable exception, obviously not alone.)
So Karl Marx and Max Weber are just chopped liver?
Ah true point. Perhaps the addition /in the modern scientific era/ would be in place. Begging the question when that starts of course. Let’s say that economics was earlier embracing quantitative techniques in the 20th century and that there was a rift between the fields especially when sociology was young that nowadays is less pronounced. It’s all interpretation.
I would have said that the 1960s and part of the 1970s were filled with attempts to synthesize, among other things the fields you've mentioned. It wound down with Reagan and Thatcher's elections, which may or may not be proximate cause - the new right at that time were certainly not fond of the humanities in any way.
