Cost AdvantageEconomies of experience curve and the benefits of market shareSources of cost advantageUsing the value chain to analyze costsCurrent approaches to managing costsOUTLINEThe Experience CurveThe “Law of Experience”The unit cost value added to a standard product declines by a constant % (typically 20-30%) each time cumulative output doubles.Cost per unit of output (in real $)Cumulative Output1992199419961998200020022004Examples of Experience Curves100K 200K 500K 1,000K 5 10 50 Accumulated unit production Accumulated units (millions) (millions) 1960 Yen15K 20K 30KPrice Index50 100 200 30070% slope75%Japanese clocks & watches, 1962-72UK refrigerators, 1957-71The Importance of Market Share If all firms in an industry have the same experience curve, then: Change in relative costs over time = f (relative market share) This supported by PIMS data:BUT: - Association does not imply causation - Costs of acquiring market share offset the returns to market shareROS (%)-2 0 5 100-10 10-20 20-30 30-40 over 40Market Share (%)Drivers of Cost AdvantagePRODUCTION TECHNIQUESPRODUCT DESIGNINPUT COSTSCAPACITY UTILIZATIONRESIDUAL EFFICIENCYECONOMIES OF LEARNINGECONOMIES OF SCALE Organizational slack; Motivation & culture; Managerial efficiency Ratio of fixed to variable costs Speed of capacity adjustment Location advantages Ownership of low-cost inputs Non-union labor Bargaining power Standardizing designs & components Design for manufacture Process innovation Reengineering business processes Increased dexterity Improved organizational routines Indivisibli\ties Specialization and division of laborEconomies of Scale: The Long-Run Cost Curve for a PlantUnits of outputper periodMinimumEfficientPlant SizeCost perunit ofoutputSources of scale economies:- technical input/output relationships- indivisibilities - specializationThe Costs Developing New Car Models (including plant tooling) $ billionFord Mondeo/ Contour 6GM Saturn 5Ford Taurus (1996 model) 2.8Ford Escort (new model 1996) 2Renault Clio (1999 model) 1.3Chrysler Neon 1.3Honda Accord (1997 model) 0.6BMW Mini 0.5Rolls Royce Phantom (2003 model) 0.310 20 50 100 200 500 1,000 Annual sales volume (millions of cases)Advertising Expenditure ($ per case)0.02 0.05 0.10 0.15 0.20CokePepsiSeven UpDr. PepperSpriteDiet PepsiTabFrescaDiet RiteDiet 7-UpSchweppesSF Dr. PepperDespite the massive advertising budgets of brand leaders Coke and Pepsi, smaller brands which incur the highest advertising costs per unit of salesScale Economies in Advertising: U.S. Soft DrinksCost Advantage in Short-Haul Passenger Air TransportCosts per Available Seat-Mile (1993) Southwest Airlines United Airlines (cents) (cents)Wages and benefits 2.4 3.5Fuel and oil 1.1 1.1Aircraft ownership 0.7 0.8Aircraft maintenance 0.6 0.3Commissions on ticket sales 0.5 1.0Advertising 0.2 0.2Food and beverage 0.0 0.5Other 1.7 3.1Total 7.2 10.5Key Stages in Applying the Value Chain to Cost Analysis: The Case of Automobile ManufactureSTAGE 1.
