Answer:
The real and nominal value of the wages you pay.
Step-by-step explanation:
Real wages are the value of wages that are adjusted for inflation and an increase reflects in an individual being able to buy more with their wages earned.
Nominal wages is a rate that is not adjusted for inflation.
In this instance you are paying the workers more in goods than before, so their salarie's purchasing power has increased. This increase reflects an increase in both real and nominal wage rates.
