Real wages
Real wages are wages 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 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 because changes in the relative prices.
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. There are further limitations in the traditional measures of wages, such as failure to incorporate additional employment benefits, or not adjusting for a changing composition of the overall workforce.
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.
Real wages are a useful economic measure, as opposed to nominal wages, which simply show the monetary value of wages in that year.
Example
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
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.
The nominal wage increases a worker sees in his paycheck may give a misleading impression of whether he is "getting ahead" or "falling behind" over time. For example, the average worker’s paycheck increased 2.7% in 2005, while it increased 2.1% in 2015, creating an impression for some workers that they were "falling behind". However, inflation was 3.4% in 2005, while it was only 0.1% in 2015, so workers were actually "getting ahead" with lower nominal paycheck increases in 2015 compared to 2005.
Trends
Historically, the trends of real wages are typically divided into two phases. The first phase, known as the Malthusian phase of history, consists of the period of time before the mass modern economic growth that began around 1800. During this phase, real wages grew very slowly, if at all, since increases in productivity would typically result in equivalent population growth that offset this increased production and left the income per person relatively constant in the long run. The second phase, known as the Solow phase, occurred after 1800 and corresponded with the massive technological and societal improvements brought about by the industrial revolution. In this phase, population growth has been more restrained, and as such real wages have risen much more dramatically with rapid increases in technology and productivity over time.Following the recession of 2008 real wages globally have stagnated with a world average real wage growth rate of 2% in 2013. Africa, Eastern Europe, Central Asia, and Latin America have all experienced real wage growth of under 0.9% in 2013, whilst the developed countries of the OECD have experienced real wage growth of 0.2% in the same period. The International Labour Organisation has stated that wage stagnation has resulted in "a declining share of GDP going to labour while an increasing share goes to capital, especially in developed economies."
The Economic Policy Institute has blamed "intentional policy choices" by governments for real wage stagnation in this period. Stating "the abandonment of full employment as a main objective of economic policymaking, declining union density, various labor market policies and business practices, policies that have allowed CEOs and finance executives to capture ever larger shares of economic growth, and globalization policies" have resulted in stagnant real wages in a time of increasing productivity.
United States
Using the PCE, the real wages of a typical worker have increased by 32% over the past three decades. Median wages — for all workers, not just production and nonsupervisory workers — grew by 25% over the past three decades. Wages for the bottom 20% of workers grew by more than one-third.The Economic Policy Institute stated wages have stagnated in the United States since the mid 1970s, failing to keep up with productivity. According to them, between 1973 and 2013, productivity grew 74.4% and hourly compensation grew 9.2%, contradicting economic theory that those two should rise equally together. However, the Heritage Foundation says these claims rest on misinterpreted economic statistics. According to them, productivity grew 100% between 1973 and 2012 while employee compensation, which accounts for worker benefits as well as wages, grew 77%. The Economic Policy Institute and the Heritage Foundation used different inflation adjusting methods in their studies.
Besides rising benefit costs, proposed causes of wage stagnation include the decline of labor unions, loss of job mobility, and declining employment by the manufacturing sector.
Between June 2016 and June 2017, wages in the United States grew by 2.5%. Factor in inflation, and that level is close to 1% growth for the period.
