This pathbreaking book - the first of its kind - critically evaluates the place of women in the development of the neo-classical school of economics. It traces the origin of the school's approach to women and exposes the bias in methodology and discourse which has characterized the school's treatment of women and their place in the capitalist economy. The roots of women's invisibility are sought first in the writings of Adam Smith. The work of John Stuart Mill subsequently allows a study of an isolated attempt to integrate a feminist awareness into economic theory. The limits in Mill's writings are contrasted to the more radical ideas of his feminist contemporaries, Harriet Taylor and Barbara Bodichon. The book then examines the debate on equal pay for men and women which took place between 1890 and 1925. In conclusion it critically evaluates the work of Marshall and Pigou.
