What is the per-worker production function graph
The per-worker production function graph is a graphical representation used in economics to illustrate the relationship between inputs (such as capital and labor) and output (goods or services produced) in a given period, while holding other factors constant.
This graph typically displays the relationship between the quantity of capital per worker (on the x-axis) and the output per worker (on the y-axis). It helps depict how changes in the amount of capital (or other inputs) affect the level of production achieved by each worker.
