Economic Foundations for Entertainment, Media, and Technology Production and Cost in E&M Industries Spring 2001 (4) Professor W. Greene
Production and Cost • Production Functions • Costs of Production • Economies of Scale and Scope • Technological Change • Integration: Horizontal and Vertical • Economic Profits
The Production Function • Output • Inputs – The factors of production • The “process” Labor Capital Materials ?
About Production Functions • Factors and Factor Intensity • Higher education • Broadway Theater – Labor intensive • Major League Baseball - ??? • Casino – Capital intensive • Multiple stages of production Outputs as downstream inputs
Multiple Stages in Production The TV broadcast Capital Equipment Labor The game The viewer Players Capital Equipment TV Sports F(x) F(x) What’s better for this process, one firm or two?
Production Functions • Managing a multiplex • Casino • Making movies (indies vs. studios) • Professional sports • Delivery of professional sports • Music • Publishing
The Costs of Production • Fixed cost: Not a function of output. Capital • Sunk cost: One time, nonrecoverable costs (very significant in the movie business) • Variable cost: Variable with respect to output • Labor • Materials • Marginal cost: Avoidable cost of one more (less) unit
Economies of Scale • Working definition: Declining average cost • Market based definition: Competitive advantage of large size • Sources • Supply based: Technical, • Demand based: Networks • Indivisibilities: Lumpiness
Economies of Scale in EMT • Cablevision • Professional sports • Publishing/Movies – Backlists of titles • Casinos • Movies • Television • Telecommunications • Web based businesses
Economies of Scope • Cost effect C(Q1,Q2) < C(Q1,0) + C(0,Q2) • Not the effect behind vertical integration • Applications? • Cable TV, Internet (convergence?) • Basketball, Hockey
Technical Advance Average total cost Cost Reduction Digital setup in newspapers Product innovation: Adult orthodontics Rapid, disruptive product innovation Seagate disk drives Satellite delivery of electronic content (Cablevision?) t1 t2 t3 Output
Digitizing Entertainment – Technical Advance in Delivery of Existing Forms • Music • MP3 - affects distribution, not creation • Pop music without musicians. (Britney Spears) • Literature: • E-books?? (Maybe not yet) • E-zines (Slate.com) • Web based news services (NYTimes.com) • Movies: • Creation – digital equipment • Distribution – transmission without film • Exhibition – digital projection (expensive)

Integration of Firms Markets Financial Services Professional Sports Traditional Publishing Final Consumers
Theoretical Departure Pointon Firm Integration • Perfectly Competitive Markets • All firms atomistic price takers • All firms fully informed and efficient • Reasons for firm integration: None • Reasons against integration: None • Reasons we observe integration: • Reaction to market failure of some sort • Creation of a market failure
Conglomerate Mergers Markets Financial Services Professional Sports Traditional Publishing Why do this? Why do we observe this?
Economies of Scope? Markets Financial Services Professional Sports Traditional Publishing Sports broadcasting and newspaper
“Synergistic” Mergers • Firms in related industries • Not a conglomerate merger • Exploitation of commonalities • Are there economies of scope? • Applications? • Hockey and basketball? • Newspapers and book publishing? • Others?
Horizontal Integration Markets Financial Services Professional Sports Traditional Publishing What objective?
Horizontal Mergers • Increases market share • Extends market power forward • Monopolization • Hirfindahl index =firms(market shares) (S1+S2) = S1 + S2 + 2 S1 S2 • May extend market power backward • What justifies horizontal integration? • Economies of scale • “Synergies?” (What is this?) • Capture market power • Application: The media mogul 2 2 2 2
Vertical Integration Markets Financial Services Professional Sports Traditional Publishing Final Consumers
Benefits of Vertical Integration All arise from some market failure • Lower transaction costs: Firm organizational limitations • Transactions involving information • Avoidance of government restrictions, taxes, or regulations. • Extension of market power (forward or backward) • Avoidance of upstream market power • Assurance of steady or reliable input supply • Murdoch’s (alleged) attempt to influence staffing decision of a baseball field manager before a broadcast • Internalization of market failures • Franchising reduces problems of free riding
Costs of Vertical Integration • Private costs • Loss of economies of scale • Organizational complexity • Assumption of risk • Social costs • Creation or extension of market power • Possible cartelization
Vertical Integration in EMT • Analysis • Where is it observed? • What are the benefits / motivation? • What are the costs? • Applications • Seagram and Vivendi • Cablevision and home delivery of cable generally • End to end production • Internet service providers and cable operators • The movie business (at several stages)
AOL Time Warner • AOL Internet service provider Instant messaging • Time Warner Time Warner Cable Time Inc. (Magazines) HBO Turner Broadcasting The WB Network New Line Cinema Warner Music Time Warner Publishing Warner Brothers Studio • Horizontal vs. vertical integration • What kind of merger is this?

Profits in Multistage and Multiple Output Processes • Allocation of revenues to activities • Multiple revenue sources (outputs) • Allocation of costs to activities • Fixed costs in multiple output firms • Net vs. gross in Hollywood A Miami Fish Story
Economic Profits and Losses • Opportunity cost of capital • Valuing an investment? t=years • Economic value of a business • How to do this? (Offer the business for sale.) • When is a business “losing money?” Profits in year t (1 + r) t
