TANGENCY: A geometric condition that occurs when two curves touch at a single point with identical slopes at that point. This condition of tangency surfaces in several different areas of economic analysis, including indifference curve analysis (tangency between an indifference curve and budget line) and monopolistic competition (tangency between demand curve and long-run average cost curve). The tangency between two curves should be contrasted with the condition of intersection, in which two cross at a single point but do not have identical slopes.

DERIVED DEMAND

The notion that the demand for a factor of production, or an input used in the production of a good, depends on the demand for the output being produced. This concept highlights the two key aspects of factor demand. One is that factor demand depends on the value of the good being produced. Inputs that produce more valuable outputs are themselves more highly valued. Two is that factor demand depends on the productivity of the input. Inputs that produce more output are themselves more highly valued.
