Discrimination of women in the labor market requires appropriate policy interventions. Affirmative action policies typically advocate the introduction of an employment quota uniformly applied to all firms. In a heterogeneous labor market such a policy may yield avoidable welfare losses. We propose a tradable employment quota showing its effects on wages, employment, and welfare in a labor market with search frictions and taste discrimination. A tradable employment quota appears to be a viable alternative yielding superior labor market outcomes.
