Questions & Answers

Q: What is the difference between diversifiable and undiversifiable risk?

Diversifiable risk refers to risks that can be reduced or eliminated through diversification, such as the risk of house fires. Undiversifiable risk, like earthquakes, cannot be diversified away.

Q: How does diversification work in stock portfolios?

Diversification in stock portfolios involves holding a variety of stocks to reduce individual risk. By pooling investments in a well-diversified portfolio, risk can be reduced by about half, while maintaining the same expected return.

Q: What is the fundamental trade-off in corporate finance?

The fundamental trade-off in corporate finance is between efficiently running a privately-held firm with high individual risk or going public and diversifying risk at the cost of reduced incentives for efficiency.

Q: Why do wealthier societies have fewer children?

In wealthier societies, the decrease in child mortality has reduced the need for diversification through having more children. Instead, parents invest more heavily in a smaller number of children.
