2. Concentration: Measurements andConcentration: Measurements and
TrendsTrends
Analysis of a firm’s competitive
environment requires identifying the key
elements of industry structure
Number and size distribution of firms
Seller concentration
Number of firms, size of firms
3. Market and Industry DefinitionMarket and Industry Definition
Product dimension
Geographic dimension
Cross price elasticity of demand
Cross price elasticity of supply
4. Geographic Market DefinitionGeographic Market Definition
Determines whether an increase in the
price of a product in one geographic
location significantly affects either
demand or suupy in another location
If so, both locations should be considered
same
Regional market
5. Market vs IndustryMarket vs Industry
Market:S&D
Industry – all products or enterprises
with large long run cross elasticities
either supply and demand should be
combined into a single industry.
7. Measures of ConcentrationMeasures of Concentration
Seller concentration: An indicator of the
number and size distribution of firms can
be measured at two levels:
◦ For all firms that form part of an economy
located within some specific geographic
boundary
◦ For all firms classified as members of some
industry or market again located within some
specific geographic boundary

Pattern of specialization across
industrialized world:
◦ Europe: Specialize in traditional industries,
◦ Japan and US: Specialize in technology
oriented industries

Industry cluster policies are a current
trend in planning for economic
development.
The focus of cluster policies is based on
the recognition that firms and industries
are interrelated.
The idea is that ties among firms within
clusters might be turned into competitive
advantage for the region.
