Real wages in the US from 1964 to 2004 have fluctuated. They have remained mostly stagnant over this period of time.

The term real wages refers to wages that have been adjusted for inflation, or, equivalently, wages in terms of the amount of goods and services that can be bought. This term is used in contrast to nominal wages or unadjusted wages. Because it has been adjusted to account for changes in the prices of goods and services, real wages provide a clearer representation of an individual's wages in terms of what they can afford to buy with those wages - specifically, in terms of the amount of goods and services that can be bought. However, real wages suffer the disadvantage of not being well defined, since the amount of inflation (which can be calculated based on different combinations of goods and services) is itself not well defined. Hence real wage defined as the total amount of goods and services that can be bought with a wage, is also not defined. This is due to the fact that changes in the relative prices of goods and services will change the financial comparability of various bundles of goods and services.

Despite difficulty in defining one value for the real wage, in some cases a real wage can be said to have unequivocally increased. This is true if: After the change, the worker can now afford any bundle of goods and services that he could just barely afford before the change, and still have money left over. In such a situation, real wage increases no matter how inflation is calculated. Specifically, inflation could be calculated based on any good or service or combination thereof, and real wage has still increased. This of course leaves many scenarios where real wage increasing, decreasing or staying the same depends upon how inflation is calculated. These are the scenarios where the worker can buy some of the bundles that he could just barely afford before and still have money left, but at the same time he simply cannot afford some of the bundles that he could before. This happens because some prices change more than others, which means relative prices have changed.

The use of adjusted figures is used in undertaking some forms of economic analysis. For example, to report on the relative economic successes of two nations, real wage figures are more useful than nominal figures. The importance of considering real wages also appears when looking at the history of a single country. If only nominal wages are considered, the conclusion has to be that people used to be significantly poorer than today. However, the cost of living was also much lower. To have an accurate view of a nation's wealth in any given year, inflation has to be taken into account and real wages must be used as one measuring stick.

An alternative is to look at how much time it took to earn enough money to buy various items in the past, which is one version of the definition of real wages as the amount of goods or services that can be bought. Such an analysis shows that for most items, it takes much less work time to earn them now than it did decades ago, at least in the United States.[1]

Real wages are a useful economic measure, as opposed to nominal wages, which simply show the monetary value of wages in that year.

Example[edit]

Consider an example economy with the following wages over three years. Also assume that the inflation in this economy is 2% per year:

  • Year 1: $20,000
  • Year 2: $20,400
  • Year 3: $20,808

Real Wage = W/i (W= wage, i= inflation, can also be subjugated as interest).

If the figures shown are real wages, then wages have increased by 2% after inflation has been taken into account. In effect, an individual making this wage actually has more ability to buy goods and services than the previous year. However, if the figures shown are nominal wages then real wages are not increasing at all. In absolute dollar amounts, an individual is bringing home more money each year, but the increases in inflation actually zeroes out the increases in their salary. Given that inflation is increasing at the same pace as wages, an individual cannot actually afford to increase their consumption in such a scenario.
