This dissertation explores several issues on family economics. Chapter 2 uses a large and nationally representative sample to investigate the effects on children's education from their grandparents and extended families including uncles and aunts. Chapter 3 compares warm glow and pure altruism when they are both used to model parental love. The comparison focuses on their implications for fertility decisions and educational investments in the children. Chapter 4 studies the fertility and education investment choices of parents when they hold both pure altruism towards their children and hyperbolic discounting preferences of their own.
