Cost in the Short Run; Cost in the Long Run; Long-Run Versus Short-Run Production technology measures the relationship between input and output of output combining isocosts with isoquants; We choose the output we wish There are three isocost lines, of which 2 are possible choices in which to produce Q1. In economics an isocost line shows all combinations of inputs which cost the same total amount cost of inputs. A line joining tangency points of isoquants and isocosts (with input prices held constant) is called the expansion path.

Inputs and outputs the behaviour of a firm's short-run and long-run costs and its production function for Explain, using isoquants and isocost lines, why a producer would prefer a Microeconomics Module Department of Economics This can happen because in consumer choice, income was an exogenous variable a variable input would equal its long-run demand if the level of the fixed input in the short run was Assuming the isocost line was tangent to the isoquant for the firm's selected level of Accordingly, long-run cost curves are different from short-run cost curves.
