In this sense, labour is an activity which creates/maintains economic value pure and simple, which could be realized as a sum of money once labour's product is sold or acquired by a buyer. The value-creating ability of labour is most clearly visible when all labour is stopped, for example during a strike or a disaster.
For example, if both capital and labor inputs are doubled, output of the commodities is doubled. In other terms the production function of both commodities is " homogeneous of degree 1". The assumption of constant returns to scale CRS is useful because it exhibits a diminishing returns in a factor.
Note: if the product resulting from the labor process is homogeneous (all similar in quality and traits, for example, all cups of coffee) then the value of the period's product can be divided by the total number of items (use-values or ) produced to derive the unit value of each item.
The total labor power of society, which is embodied in the sum total of the values of all commodities produced by that society, counts here as one homogeneous mass of human labor power, composed though it be of innumerable individual units...The labor time socially necessary is that required to produce an article under the normal conditions of ...
If a production function is homogeneous of degree one, it is sometimes called "linearly homogeneous". A linearly homogeneous production function with inputs capital and labour has the properties that the marginal and average physical products of both capital and labour can be expressed as functions of the capital-labour ratio alone.
Postone examines the fact that abstract labor is not (concrete) labor in general but has a unique social dimension that cannot be derived from (concrete) labor as such: it mediates a new, quasi-objective form of social interdependence. Abstract labor is a historically specific mediating function; it is the content or 'substance' of value. Labor ...
A textbook treatment of the matching approach to labor markets is Christopher A. Pissarides' book Equilibrium Unemployment Theory. [1] Mortensen and Pissarides, together with Peter A. Diamond, were awarded the 2010 Nobel Prize in Economics for 'fundamental contributions to search and matching theory'. [2]
where Q is output, A is factor representing technology, K is the sum of the value of capital goods, and L is the labor input. The price of the homogeneous output is taken as the numéraire, so that the value of each capital good is taken as homogeneous with output. Different types of labor are assumed reduced to a common unit, usually unskilled ...
