The researchers studied how changes in electricity prices affect how much electricity people use in their homes in New York. They looked at data from different areas in New York over 20 years. They found that when prices go up, people use a little less electricity right away, and a bit more less in the medium term. But in the long run, they use a lot less. They also found that the impact of price changes on electricity use varies depending on factors like income, weather, and time period. This means that one-size-fits-all policies based on price changes might not work well for everyone.
