And unlike European countries whose productivity also exceeds Britain's, America's higher labour efficiency has not come at the expense of fewer jobs and hours worked.
Of that, more later: the issue of labour efficiency is more complex than it may seem.Whatever the changes to come, though, the biggest has already happened.
Applied to traditional farming equipment such as tractors, harvesters, ploughs and sprayers, it has enhanced labour efficiency and helped curb costly waste by enabling large-scale crop farmers to harvest and spray fields with pesticide and herbicide with centimetre accuracy.
In the National Health Service, for example, which has devoured so much extra cash, efficiency has been declining by about 1% a year.The deterioration in labour efficiency overall is a particular worry for Mr Brown, for productivity growth is the mainstay of the economic expansion that in turn underpins the public finances.
Mobile rose systems are designed to increase labour efficiency.
These results show that optimisation of parlour performance and approximation to maximum labour efficiency should be addressed differently depending on the characteristics of the farm; in some cases, an improvement in management activities is necessary.
The Act has potential to bring rich dividends especially in rural areas as access to food for poor means improvement in their productivity, labour efficiency, reduced expenditure on health and reduced migration to cities.
As the demographic dividend gradually disappears, improving labour efficiency will be the primary means by which to improve the income of the working class as well as its ability to consume.
In this 'wage-setting schedule', real wage accepted by workers (adjusted for trend growth in labour efficiency) varies with the unemployment rate: the higher the unemployment rate, the lower real wages will be.
