Q&A

How does making a lot of money in finance affect one's perception of the average person?

It can lead to isolation and a distorted view, as the wealthy become disconnected from the struggles of the average person.

What is non-linearity in finance?

Non-linearity refers to the fact that financial models cannot simply multiply or scale linearly. The relationships between variables are more complex and can't be predicted solely based on linear math.

Why are financial models reliant on future predictions?

Financial models attempt to estimate the value of securities and investments based on assumptions about the future, such as interest rates or prepayment rates. These predictions guide decision-making and pricing.

What is the role of mathematical equations in finance?

Mathematical equations in finance help represent complex financial concepts and relationships in elegant and concise ways. They simplify and provide a framework for understanding the intricacies of the market.

Were mathematical models solely responsible for the global financial crisis?

No, the crisis was caused by a combination of factors including incentives, systemic flaws, and over-reliance on faulty assumptions. Mathematical models were not the sole cause, but they were one piece of the puzzle.
