THREAT OF ENTRY
•Capital requirements •Economies of scale •Absolute cost advantage •Product differentiation •Access to distribution channels •Legal/ regulatory barriers •Retaliation
Pharmaceuticals
• Power of buyers
– Limited
• Purchase decisions made by powerful medical profession able to influence what the state or insurance co. must pay for
SUPPLIER POWER
• Buyers’ price sensitivity
• Relative bargaining power
INDUSTRY RIVALRY
•Concentration
•Diversity of competitors
•Product differentiation
•Excess capacity & exit barriers
• These substitute products place a cap upon industry prices above which buyers will desert

The threat of entry
• Threat that new entrants will start up, increase capacity and competition and erode profits
• Depends on the size of the entry barriers
• Eg scale economies, patents
B
4
The threat of substitution
• Threat other industries will take business away:
– eg aluminium industry faces threat from glass, plastics, steel
• Deregulated
• Low start up costs
• Modest economies of scale
• The threat of substitution
• High in some short haul routes
• lower in long haul
• The power of the buyers
– Eg airlines
• Others are non price competitive and highly differentiated in products
– Eg pharmaceuticals

Competitive Rivalry
• The degree of competition within the industry for market share
– Especially the degree of price competition
• Some industries are very price competitive
• Power of suppliers
– Negligible
• Drug ingredients are largely commodities, widely available
• Competitive rivalry
– Limited
• Little or no price competition
• Depends on buyer concentration, information, switching costs
– Eg fragmented horticulture industry faces concentrated, expert buyers with low switching costs

Power of suppliers
• Ability of suppliers to dictate the terms and conditions of supply
– Supply concentration and differentiation is key
• Eg operating system component of PC • Eg the transmission system in bicycles
new drugs • Very large medical sales force required
• The threat of substitution
– Very low
• Often no alternative to a drug in dealing with an illness

Some comments on the method
• Very similar to the structure, conduct performance model
– Old wine in a new bottles?
• Porter stresses that the five forces are the only factors: there never any others
– The threat of entry – The threat of substitution – The power of the buyers – The power of the suppliers – Competitive rivalry within the industry
