The article explores how people make decisions about the future by looking at different ways of discounting future rewards. The researchers developed a framework that includes both exponential and quasi-hyperbolic discounting, focusing on the common phenomenon of decreasing impatience. They found that people tend to be less impatient over time compared to what a simple exponential model predicts. By applying this framework to a standard growth model, they studied how the economy evolves over time and how stability is affected. They also considered how habits influence economic growth in their analysis.
