8. Consider the Equation of Exchange in its form that shows changes in the variables over time. If we assume velocity is constant over the long term and the long-term average rate of growth in the real economy that is sustainable is around 3%, what is the implication for the relationship between the growth in the money supply and changes in the average price level in the economy? 8.
