Document Summary

Economies of scale: when average cost declines as output increases marginal cost of last unit produced must be less than ac (advantage of producing larger output) Key determinant of a firm"s horizontal boundaries: the qty and variety of products/services that it produces. Average cost curve: captures relationship between ac and output. U-shaped because initially spreads fixed costs over increasing output eventually rises as production runs against capacity constraints. When l-shaped (usually in long run) ac decline up to minimum efficient scale (mes) = firms can expand capacity by building new facilities (ac stops rising) Scope economies if: tc (qx, qy) < tc (qx,0) + tc(0,qy) or tc(qx,qy) . Example, makes more sense for a tape manufacturer to diversity into production of adhesive message notes than to produce unrelated products. 4 major sources of scale and scope economies : indivisibilities and the spreading of fixed costs.
