Het statistische verband tussen arbeidsproduktiviteit en produktie

The statistical relation between labour-productivity and production.
Rising labour productivity can be induced by increases in output, or result from "autonomous" factors. Many induced increases will be irreversible, in particular those associated with "learning" processes. Under conditions of continuous economic growth the learning curve hypothesis leads to a simple exponential relation between labour demand and output in the long run.
In the short run, current and past profits and the profitability of import substitution join output as explanatory factors of labour demand.
In the long run, the effect of growth of capital must be taken into account. Autonomous factors can be represented by an exponential trend. With United States data, increasing returns to scale are still found. Under conditions of a constant savings ratio and continuous population growth a production function, which takes account of all these factors, can be shown to be compatible with a constant labour-output elasticity, however.
