In longrun analysis of production, all inputs are variable and isoquants are used to study production decisions.
What is the difference between an isocost and an isoquant. As labour increases, ceteris paribus, output increases. The iso quant closer to the origin indicates a lower level of output. Beyond point e, the distance between the successive isoquants representing equal increments in output is decreasing along the ray or from the origin which implies that less than proportionate increase in output is obtained from a given proportionate increments in the use of the two factors, labour and capital on the ray or from the origin, ef. With a single output and input, a cobbdouglas production function. Production function of a single input single output firm source.

Both a general algebraic derivation of the problem and the optimality conditions and speci. The isoquant curve is negatively sloped, which means, in order to have a same level of production, the more use of units of one input factor is to be offset with the lesser units of another input factor. Isoquants an isoquant is a curve that shows the efficient combinations of labor and capital that can produce a single iso level of output quantity. This is however inconsistent since c 100 and b 200.
