问题如下：
If the nominal interest rate is 2% and the rate of inflation is 3%, what is the real interest rate? How should it be interpreted?
解释：
The real interest rate is -1%. When an investor earns 2%, the investor’s purchasing power actually decreases by 1% per year because of inflation.
请问这个和名义利率加1等于真实利率加1乘以通胀率加1有什么区别
