In Thailand, where years of educational equality have combined with a profession that rewards math skills and merit, women comprise 31 percent of board and executive committee members in financial services — some way short of parity but the highest proportion in the world after Norway and Sweden, according to a study last year by consulting firm Oliver Wyman. In the US, the representation of women in similar positions is 20 percent. Japan is at the bottom of the list, with 2 percent. Women account for 57 percent of Thailand’s finance and insurance workforce, according to government statistics. Yet the fact that two-thirds of senior management and executive roles are filled by men indicates Thai women still face challenges in achieving equality, said Joni Simpson, a specialist on gender, equality and nondiscrimination at the International Labor Organization in Bangkok. Accounting is a field that is accessible to women in Thailand, and therefore they have been able to advance in this sector.
