The article "Patterns in Household Demand and Saving" by Lluch, Powell, and Williams explores how households spend and save money. The researchers studied different patterns in how people use their income. They found that households tend to spend more on certain items, like food and housing, and save less when their income increases. This means that as people earn more money, they don't necessarily save more. This research helps us understand how people manage their finances and make decisions about spending and saving.
