Assignment Brief
Potentially Important Elements to include in analyzing a Commodity Market (examples only)
-
World price levels, and path since ~2000 or preferably back longer; world market vs local market
-
For changing prices over time, can you distinguish between demand and supply growth?
-
Is price volatility especially significant?
-
Output levels, worldwide vs local country
-
Time series: is production growing or stable? Is there any likely explanation (e.g., from previous research)?
-
Information on technical change, yield growth, other productivity questions
-
Where is research taking place? Which countries are leaders in technology changes, or is it in CGIAR centers?
-
Yield threats due to pests, diseases, climate changes?
-
Other production-related issues?
-
Time-related: changing comparative advantages across countries?
-
Special Issues: Different qualities for sale, any quality distinctions in pricing, output
-
Different varieties if differences in qualities are less important (e.g., in apples)
-
By-products of importance
-
Key producing countries, importing countries
-
Proportion of world output that is traded (thickness or thinness of market)
-
Policy measures in domestic market(s)? Alternatively, are there important market institutions?
-
Any that have impact on world prices
-
Linkages between domestic market and world market?
-
Particular segmentation of world market? Price discrimination against certain markets?
-
Value added in processing? What share of wholesale price received by farmers?
-
Processing-related issues? Joint products? Concentration? Dynamics over time?
Example 1
Ethiopian coffee key issues. Net exporter of generally very good quality coffee; wide range of prices from no capture of quality premium to a strong premium (available only to direct exporters); few firms, coops can export directly and all others must sell through exchange with no quality premium; competitive trading system; all smallholder coffee (no plantations); growing domestic consumption reducing quantity available for export; price trend not known; tight linkage between export and domestic markets; Ethiopia mostly a price-taker on world markets, but with potentially large quality premium.
Example 2
Key Issues from Vietnamese export/production patterns and growth
-
incredibly rapid production growth; equally rapid export growth
-
shift from ‘small country’ to ‘large country’ in those 6-7 commodities
-
little government ‘support’; no subsidy, little input market provision (via policy)
-
role of SOEs?
-
Expectation of future export growth? Would you invest in VN’s export commodities?
