sentences:  Since the late 1960s, Marglin, following the lead of people such as Samuel Bowles, Herbert Gintis, and Arthur MacEwan, rejected orthodox economics and began expressing dissenting views in his academic work.According to his former teacher, James Duesenberry, Marglin's career subsequently "suffered" because of his department and the university authorities in general taking a negative view of this change.Economist Brad DeLong noted in a similar vein that the wider community of "Ivy League economists" took a rather dim view of Marglin's post-tenure "deviancy", something that has "not been pretty" to observe.
