The real wage ($w$) is defined as the nominal wage ($W$) divided by the general price level ($P$). This relationship is expressed by the formula: $w = \frac{W}{P}$. It is a foundational assumption within the WS-PS model.

Formula for the Real Wage

An individual's annual nominal earnings increase from $50,000 to $52,500. During the same period, the general price level index rises from 1.0 to 1.05. Based on this information, what has happened to the individual's purchasing power?

A company's management team wants to ensure their employees' purchasing power does not decrease next year. They anticipate that the general price level will increase by 3%. What percentage change in the nominal wage must the company provide to keep the real wage constant? Explain your reasoning.
