(a) Why do you think population growth rates fall with development? If people consume more goods, in general, as they get richer and children are just another consumption good (a source of pleasure to their parents), then why don’t people in richer countries “consume” more children?

(b) Why are countries with higher population growth rates likely to have a greater proportion of individuals below the age of 15?

(c) Are poorer countries more likely to be rural or is it that rural countries are more likely to be poor? Which way does the causality run, or does it run both ways?

(d) Why do you think the international price of sugar might fluctuate more than, say, that of automobiles?
