Definition

The wage share can be defined in various ways, but empirically it is usually defined as total labor compensation or labor costs over nominal GDP or gross value added. Often the capital share and labor share are assumed to sum to 100%, so that each can be deduced from the other. For example, the

defines the labor share in a given sector (''LS'') as the ratio of labor compensation paid in that sector (''C'') to current dollar output (''CU''), ie. ''LS = C / CU''. The non-labor or capital share (''NLS'') is defined as 1 − ''LS''. In '' Capital in the Twenty-First Century'', Piketty described the

accounting identity In accounting, finance and economics, an accounting identity is an equality that must be true regardless of the value of its variables, or a statement that by definition (or construction) must be true. Where an accounting identity applies, any dev ...

''α'' = ''r'' × ''β'' as the 'first fundamental law of capitalism', where ''α'' represents the capital share, ''r'' is the rate of return on capital, and ''β'' is the capital to income ratio. Piketty defined the wage share as 1 − ''α''. Because the self-employed perform labor which is not rewarded with

s, the labor share may be underestimated in sectors with a high rate of self-employment. One approach is to assume the labor share of proprietors' income to be fixed. The OECD and the Bureau of Labor Statistics adjust labor compensation by assuming that the self-employed have the same average wage as employees in the same sector.

". Cobb and Douglas's '' Theory of Production'' (1928) introduced empirically-determined constants ''α'' and ''β'' which corresponded to the capital and labor share respectively. Cobb and Douglas found that the wage share was about 75%. For most of the 20th century, constant labor share was a stylized fact known as Bowley's law. Historical measurements of the wage share can be charted using the
