Hello, I am a history grad student currently doing my field research in Mexico City, on the urban middle-class in the 1970s and 1980s. Would anyone on this list have time to suggest some readings on the middle-class? I would be interested in theoretical works or case studies, across time and geographical location. I apologise for this general request; I have been trained as a cultural historian and want to get familiar with the methodologies of economic history and economics vis-a-vis the middle-class. Thank you, Louise Walker
