Unequal inflation
It's common knowledge that if you print more money, you will produce inflation. However, things are more complex than that. You can have both inflation and deflation in the same time. More often, we have relatively low inflation on common products and high inflation on specific products - think real estate. Money velocity First, there is that "money velocity" that equals the equation Products * Price = Money * Velocity . The money velocity is intuitive, but cannot be practically measured except from this equation - thanks to my namesake friend for this idea.
