Research shows that trade openness can increase women’s incomes and consumption. Eliminating import tariffs raises the average real income for female-headed households compared with male-headed households in more than three-quarters of the 54 developing economies analyzed. On average, real income gains reaped by removing import tariffs would be 2.5 percent greater for households headed by women than for those headed by men. In countries such as Burkina Faso and Cameroon, this increase is equivalent to one year’s spending on education or health.
Opening up to trade therefore benefits women in developing economies because it expands the sectors where women work, reduces prices for the goods women consume, and allows firms that are more productive to grow. Increased competition generated by trade also makes it costlier to discriminate against women, which narrows the wage gap and improves working conditions for women.
