This collection surveys the contributions which economists have made to our understanding of gender. The articles reflect both the strengths and weaknesses of mainstream economics in conceptualizing and explaining gender differences. They include selections from and commentaries on the classics which illustrate relevant aspects of the methodological development of economics; important treatments of the key issues such as female labour supply and male-female wage differences; recent feminist charges that economics is methodologically unsuited to the analysis of gender; and evidence on the historical significance of women's work.
