Stephen A. Marglin '59, the only radical economist left in the Department's faculty, said yesterday that the appointments will affect the quality of research in this field at Harvard.

"Research and meaningful teaching is hard to carry on in isolation," Marglin said.

Graduate students interested in radical economics have also expressed concern over the limited alternatives the Economics Department at Harvard is able to offer them.

William Lazonick, a third year graduate student here, indicated yesterday that undergraduates attracted to the non-orthodox approach will not choose Harvard as their academic haven and graduate students here looking for jobs, will search elsewhere.

Gintis urged students to fight against "faculty intransigence" and get more radical economists from other schools to come to Harvard.

Core groups of radical economists are currently clustered at American University in Washington, the New School of Social Research in New York City and the State University of New York at Stoney Brook. In 1969, when Harvard had five radical economists on its faculty, it was considered the school with the best potential for development in this field
