Family Economics Writ Large Abstract Powerful currents have reshaped the structure of families over the last century. There has been (i) a dramatic drop in fertility and greater parental investment in children; (ii) a rise in married female labor-force participation; (iii) a decline in marriage and a rise in divorce; (iv) a higher degree of positive assortative mating; (v) more children living with a single mother; (vi) shifts in ocs ial norms governing premarital sex and married women's roles in the labor market.
