Productivity is output divided by input.

So in farming it can be yield divided by labor (labor productivity), yield divided by soil addenda (e.g. fertilizer), yield in dollars divided by all costs of production, etc.

Sometimes factor productivity will have a specific name. For example capital efficiency is the productivity of capital (output divided by cap ex) which, due to the very nature of capex, is usually used to find a change due to investment. The productivity of energy use, typically measured on a whole economy basis, is called “energy intensity” (gdp/GW) though some industries are called “energy intensive”




Fascinating, thanks.
