The marginal revenue product of a worker is equal to the product of the marginal product of labour (the increment to output from an increment to labor used) and the marginal revenue (the increment to sales revenue from an increment to output): =. The theory states that workers will be hired up to the point when the marginal revenue product is ...
The following list of countries by labour productivity ranks countries by their workforce productivity. Labour productivity can be measured as gross domestic product (GDP) or gross national income (GNI) generated per hour.
Technology-driven declines in investment prices reduce the labour share. [11] On average across industries, a decline in investment prices relative to value-added prices of 9% – which is around the average decline in relative investment prices observed over the period 1995–2013 in the OECD – reduces the labour share by approximately 1.7 percentage points.
The marginal revenue product of labour can be used as the demand for labour curve for this firm in the short run. In competitive markets, a firm faces a perfectly elastic supply of labour which corresponds with the wage rate and the marginal resource cost of labour (W = S L = MFC L).
Traditional international economic theory maintains that reducing barriers to labor mobility results in the equalization of wages across countries. [1] This can be demonstrated easily with a graphical model. First, the wage rate in a particular country can be shown graphical by looking at the marginal product of labor (MPL). The MPL curve ...
The marginal product of labor is then the change in output (Y) per unit change in labor (L). In discrete terms the marginal product of labor is: . In continuous terms, the MP L is the first derivative of the production function: . [2]
An economic depression for instance, would not necessarily set off a chain of events leading back to full employment and higher wages. Keynes believed that government action was necessary for the economy to recover. In Book V of Keynes's theory, Chapter 19 discusses whether wage rates contribute to unemployment and introduces the Keynes effect.
Part I of the book takes as its starting point a reformulation of the marginal productivity theory of wages as determined by supply and demand in full competitive equilibrium of a free market economy. Part II considers regulated labour markets resulting from labour disputes, trade unions and government action. The 2nd edition (1963) includes a ...
