  Adam Smith, and Karl Marx, both believed that labour value lies at the heart of all economic value. Commodities, goods, and services arise from the interaction of land, labour, and capital. Since Land is fixed until new land is cleared or built by workers, and since capital enhances labour and is invented by people, they both thought that the only people who added value in economic transactions were workers. This theory of labour value was qualified in the second half of the twentieth century by the elevation of entrepreneurialism as a factor of production. The enterprising businesspeople who took on risks, brought factors together, and who were rewarded with profit having been prepared to make losses, were elevated to a ‘fourth factor.’ This idea makes some sense, but also serves to undermine the idea that labour value on its own creates economic value. If labour has value, some argue that the value of time taken from a life to work should be viewed equally. This means t...

  There are a number of ways to refer to the supply of labour. A precise one is that the supply is the number willing and able to work within the market at a set of wage rates for a given time. The supply curve is likely to be upward sloping as the wage required to maximise the hours people work will increase the more work that they do unless there is infinite elasticity of supply. There are across the developed world intense pressures on the supply of labour. In part, this is because of immigration restrictions which place barriers on the movement of people globally, so that national or regional labour markets are inelastic in supply. Another ‘global’ reason is the intense and accelerating decline in birth rates, which fell some time ago, or which are falling, to below replacement rates. This process means that there are fewer young people entering the workforce, and more older people in society. That in turn means that, in Japan, Korea, or Italy, for example, there is a gre...
