The study looked at how different types of wealth, like housing and financial assets, affect people's spending habits in Sweden from 1970 to 1992. By analyzing data and using special models, the researchers found that financial wealth plays a big role in how much people spend. When they looked at wealth in more detail, the models worked even better. They also discovered that changes in household debt influenced short-term spending, suggesting that people were limited by how much credit they could get. The increase in savings in the 1990s was linked to a tax change during that time.
