Document Summary

The production function with one variable input and law of diminishing. Managers need to determine optimal way to produce. They must efficiently use the scarce resources available to produce goods (output) Through efficiency of using inputs it will result in minimizing costs and maximizing profits. Production function shows maximum output given certain input. 1. 1 the production function with one variable input: In the long run all inputs become variable. In the short run it is difficult to change capital. Managers are interested in seeing how output changes as the number of workers vary. Output per worker = average product of labour = q/x1, while x2 (fixed costs are constant) Average product shows how much output each worker is responsible for making. Better measure of efficiency is marginal product which focuses on the incremental change created by small change in input. Mp = change in q / change in x.
