If you're dealing with grappling [with] problems of feeding people, the biggest impact in fertility reduction is girls' schools. Schooled girls make a bigger impact on that than any other factor - not these various regulations [such as] you have to have one child or that. It turns out that none of these are effective.

Women's education has a much greater impact [on], for example, fertility. Men's education, if our studies are correct, ha[s] almost no impact on fertility. Women's do. So, by the way, as a man, it's not to the glory of men specifically that it's women's education that reduces child mortality.

Thailand's economic development was driven by educational expansion. That has been a very dramatic factor, and South Asia had been pretty miserable in not learning from that experience.

Women had always been thought of as looking after the family when men go and earn an income and they're the bread earner and so on. So there is a kind of generation of inequality, [and], on top of the fact, women have pregnancies and periods, [and] when the children are very small, there are greater demands on their time. So one way or another women have had a pretty rough deal in the past, and there's no reason why that should continue, and any country that has tried to remedy that has succeeded in doing so.

I think gender inequality is a problem that goes back a long, long time. In human society, as a whole, women have tended to have a kind of inferior position - very often combined with playing up women as great role [models].

In India, [in] the great documents like [the] Upanishads in eighth century B.C., you find some of the wisest [women] making great, learned speeches and then you worship them, but actually don't do very much about girls' education generally. So I think there has been a kind of dual presence of pain, respect, and saying you are great, etc., but not providing the basic facilities that make women able to lead the kind of life that they would like to and that men easily do.

Sometimes the lack of substantive freedoms relates directly to economic poverty
