That is not part of our studies on the labour force, but we must provide a quarterly and a yearly estimate. We publish productivity by worker on a quarterly basis. It equals the GDP divided by the number of workers. That is labour productivity. In our annual estimates, we make an adjustment for the capital, as there are two inputs in the portion on production. Normally, to produce the GDP, you must account for work and capital. We want to separate productivity and the increase in GDP which is not based on a larger input of one or the other. It is an increase in pure productivity. We call that multi-factor productivity. Generally, both move in similar ways.
