The study looked at how changes in interest rates affect different parts of the economy. They found that the speed at which prices change is the main factor influencing the impact of interest rate changes on the economy. The connections between different sectors and how much people spend on different things also play a role. By simplifying the number of sectors, the effects of interest rate changes on the economy can be reduced. This means that the initial response of prices to interest rate changes is not enough to tell which parts of the economy are most affected.
