Real vs Nominal (Interest rates and GDP)
This post is for all those lucky public school teachers out there who make $28,000 a year. Have you ever wished that you could use those dollars in, for example, 1914. I'm sure you've considered it. Just think! If I had only been able to take $100 of my money and put it into Coca-Cola. I'd be rich!
I know you all realize this is just wishful fancy. However, I must burst your bubble further. Just as you cannot go back in time, you also cannot assume $28,000 of currency in 2008 translates into the same thing in 1914. We have to take into account that word that homeowners love (because it makes them wealthier), and teachers hate (because they live on fixed income) Inflation!
This is the difference between real and nominal variables in economics, real variables have been adjusted for inflation. For example, say as a teacher you make $28,000 a year. However, you do not receive pay raises and every year inflation causes the price level to increase by 5% generally. You might think you income is staying the same. But it turns out, to your dismay, that you are effectively receiving a 5% paycut every year!
In the same line of thinking. Let's say our GDP grew a nominal rate of 8% from 2007-2008. However, inflation was 6%. Adjusted for inflation, our GDP would have grown by a real rate of 2%.
It also works the same way for interest rates. Let's say you put money into a savings account at 2% interest. However, inflation is usually around 3% even in a healthy economy. You are in fact losing 1% of the value of your money by putting it into a savings account!
Therefore, you have to be wary of inflation when you are considering your financial future. You may think you are gaining something or only losing a little, when it fact it is more than you bargained for! Yet, inflation can be a good thing for some people. As I previously stated for someone who owns a home. If the rate of inflation is higher than the real interest rate, your home gains value by just sitting there!
The bottom line here is. Be Real!
