Isoquant

There are many ways of producing a given level of output, We can use a lot of labor with a minimal amount of capital, or we could invest heavily in capital equipment that requires a minimal amount of labor to operate, or any combination in between. For most goods, there are more than just two inputs. For example in agricultural, the amount of land, water, and fertilizer can all be varied to produce different amounts of a crop. An isoquant, in the two input case, is a curve that shows all the ways of combining two inputs so as to produce a given level of output
