Female workers in Bangladesh earn less than male workers, and this wage gap is due to discrimination. A study looked at data from 1999-2000 to understand this gap in rural and urban areas. They found that women face more discrimination in urban areas, leading to larger wage gaps. This discrimination is not just because of differences in skills or experience, but also due to bias against women. The study also showed that selectivity bias, where certain factors affect who gets hired, plays a role in this discrimination.
