  1. Mixed but not Scrambled Gender Gaps in Single-Sex Classrooms By Valentina Paredes
  2. Income taxation of couples, spouses' labor supplies and the gender wage gap By Cremer, Helmuth; Roeder, Kerstin

    Abstract: In this paper we study the effect on the math gender gap from attending a singlesex classroom in a coeducational school versus a coeducational classroom in a coeducational school. In contrast to the previous literature that has studied the effect of single-sex schools, the advantage of using single-sex classrooms is that we can calculate gender gaps within schools, and therefore the results are not confounded with other school characteristics that may correlate with the gender composition. We find that single-sex classrooms reduce the math gender gap by more than half, with no effect on the language gender gap. The effect is consistent with an increase in the math achievement of female students with no decrease in the achievement of male students. Moreover, this effect is not driven by teacher characteristics, but it seems to be driven by the gender composition of the classroom itself.

    Abstract: We study the taxation of couples when female wages do not re?ect their true productivity. We show that the expression for the marginal tax rates of the male spouses is the same as in a Mirrleesian world where wages re?ect true productivities. Marginal taxes for the female spouses are reduced because of a Pigouvian correction. Consequently, the wage discrimination pleads for a lower marginal tax on the female spouse. Furthermore, the distortion of a couples?tradeo¤ between male and female labor supply is the same as in a Mirrleesian world without a gender wage gap. It only depends on true productivities and not on wages. In other words, the tax system completely neutralizes the extra distortion introduced by the wedge between the female spouse?s wage and her true productivity.
