Abstract labour and concrete labour refer to a distinction made by Karl Marx in his critique of political economy.It refers to the difference between human labour in general as economically valuable worktime versus human labour as a particular activity that has a specific useful effect within the (capitalist) mode of production.
Most of them applied an ideologically safe "average labor time" model, which had however considerable negative influence on effectiveness by "discouraging marginal productivity gains". [11] Another criticism is that socially necessary labour time needs to be able to be measured as a homogenous unit of labour, which can then be added up.
The original H–O model assumed that the only difference between countries was the relative abundances of labour and capital. The original Heckscher–Ohlin model contained two countries, and had two commodities that could be produced. Since there are two (homogeneous) factors of production this model is sometimes called the "2×2×2 model".
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.
The model uses the variables q is output k is (homogeneous) capital w is the wage rate a is labour productivity n is the labour force. which are all functions of time (although the time subscripts have been suppressed for convenience) and the constants α is the rate of growth of labour productivity

[1] The relationship between buyers and sellers as the main body of the market includes three situations: the relationship between sellers (enterprises and enterprises), the relationship between buyers (enterprises or ...
Estimates of the labor market matching function suggest that it has constant returns to scale, that is, +. [ 3 ] If the fraction of jobs that separate (due to firing, quits, and so forth) from one period to the next is δ {\displaystyle \,\delta \,} , then to calculate the change in employment from one period to the next we must add the ...
