Economic definition of industry
A group of firms that supplies a market
What is the difference between analyzing industry structure and analyzing market structure
Principle difference is that industry analysis, notably five forces analysis, looks at industry profitability being determined by competition in two markets:
1) Product markets
2) input market
Industries
Identified with relatively broad sectors
Markets
Related to specific products
Two sides of sustainability
1) Substitutability on the demand side
2) Substitutability on the supply side
1) Substitutability on the demand side
Are customers willing to substitute between Jaguars and mass-market brands on the basis of price difference?
2) Substitutability on the supply side
If manufacturers were able to switch their production from family sedans to luxury cars, and if jaguar could could enter other parts of the automobile market
The key test of geographical boundaries of a market is PRICE:
If price differences for the same product between different locations tend to be eroded by demand-side and supply-side substitution, then these locations llie within a single market
Substitutability is ____ in the long run then in the ____ run
Long
Short
The boundaries of a market or industry are seldom clear-cut: the market in which an offering competes is a ______ rather than a bounded space
Continuum
Example: If we define Disneyland as competing within the broad entertainment industry, then beach and ski resorts are _______, if we define Disneyland as competing in the theme park industry, then bean and ski resorts are _____
Rivals
Substitutes

The Herfindahl-Hirschman Index
All slides beyond this
The Herfindahl-Hirschman Index (AKA Herfindahl index)
HHI
Is a statistical measure of concentration
Can be used to measure concentration in a number of context
(become so popular by its use by the Department of Justice and the Federal Reserve in the analysis of the competitive effects of mergers)
Score less than 1800 or a change less than 50 = no concentrated
Above 1800 is concentrated or a merger increase of larger than 50 = concentrated
Market concentration
The degree of concentration of the output of firms in banking or industrial markets
Horizontal mergers
Firms operating in the same product and geographic markets
1992 Revised Guidelines
The guidelines, as applied to banking, specify that if a bank merger would result:
1) in a post-merger HHI in a market of less than 1,800
2) in a change in the HHI of less than 200 (less than 50 in other industries),
it is likely that the market structure would not reach a concentration level, or concentration would not increase enough, such that firms in the market would have the market power to maintain prices above competitive level for a significant period
If the post-merger HHI does not exceed the numerical guidelines:
It is generally presumed that the merger would not be seriously anticompetitive, and no further analysis is conducted
If the post-merger HHI exceeds the numerical:guidelines:
A detailed economic analysis of competition is undertaken to determine whether other factors, such as potential competition, indicate that the market would be more (or less) competitive then the HHI alone suggests
The HHI accounts for:
the number of firms in a market, as well as concentration, by incorporating the relative size (that is, market share) of all firms in a market
HHI = n>E, i=1 (MSi)>2
It is on paper for easier sake
Examples: Bank A holds 40 percent of bank deposits, Bank B holds 30 percent, Bank C holds 20 percent, Bank D holds 10 percent
Assume that Bank C with 20 percent of the market acquired Bank D, which has 10 percent of the market, calculate the HHI
(40)>2+(30)>2+(20)>2+10>2
1600 + 900+ 400+ 100 = 3000
(40)>2 + (30)<2 + (20+10)<2 =
1600 + 900 + 900 = 3400
Increases HHI by 400 from 3000 to 3400
The HHI reaches a maximum at
10000 when a monopoly exists
