The article explores how people make decisions about saving money and investing based on their preferences for risk and time. By using a new model that separates these preferences, the researchers found that different factors influence how people choose to save and invest. They discovered that when the prices of goods and leisure change due to risk, people's time preferences play a big role in their decisions. On the other hand, when prices stay the same, risk attitudes become more important. The study also compared their results to a traditional model and found that their new approach provides better insights into how people make financial decisions.
