A Key Componentfor ICP 2004
A well-established product list
Compare „like with like“
Collect prices for relevant products
Establish reliable PPPs
The product list
A product list (= item list) is asample of goods and servicesthat are identified to suitablyrepresent the market and forwhich prices have to becollected.
Where are we?
Concepts: methods, approaches, coverage
Establishing of item list: pre-survey, datasources, country missions, improvement of draftlist, finalization
Preparation of price collection: sampling of outlets,translation, training of price collectors
Actual price collection, national pre-check
Multilateral editing (by regional co-ordinators); calculation ofb.h. PPPs
calculation of aggregate PPPs and results
A „Tabula rasa“situation?
Many countries make a fresh start
Previous ICP rounds were conducted longago
No office‘s „institutional memory“
OECD-Eurostat in a different situation(perpetual survey cycle)
Focus of this Session
The first step
towards the ICP item list
Information on availability of goods
Typical variants of the assortment
Identify relevant product characteristics
Two starting points
ICP-classification (expenditures)
How are expenditures grouped?
At what level of detail weights (expenditure data)can be attributed?
The role of a „minimum“ classification
The basic heading as the building block of the list
Market reality (products „consumed“)
What is offered in the various shops?
„Sampling“
•Classification - our buildingblock:
• „Basic heading“, asdefined in the ICPclassification, indicatesonly rough
product types
e.g. „Pubs, bars, cafés,tea rooms and thelike“
•On the market wefind concreteproducts
A tool for sampling
The StructuredProduct Definition –SPD
The SPD Approach
Is a tool to gain market informationusing a structured layout (checklist)
Lists item characteristics
Helps to identify relevant productvariants within a Cluster
Provides the basis for item descriptions
The effect of the SPD
To map the market into adocument – finally the itemlistTo map the market into adocument – finally the itemlist
Sources of market information
Visit of outlets
Contacts with retailers
Searching information within the office(CPI, INTERNET)
Trade fairs

Caution: the initial listing ofparameters is already somehowdetermining
Overview of available brands
Interactions betweenparts involved (SPD)
Standard forms are provided by theglobal centre
To be managed by the regionalcoordinators
Completed in close cooperation with thecountries
How to use the SPD
Revise the SPD to regional needs
Include necessary product groups, excludedispensable ones
Decide on necessary parameters per productgroup (e.g. „second hand product“)
Decide on questions about additional information

How to use the SPD
Distribute revised SPD to countries about 2weeks before initial visit
(Countries could start pre-completion on thebasis of national product baskets)
During initial visit go to shops and marketstogether with NSI-colleagues
Complete the SPD together with countrycolleagues

The first country visits
Visit a sample of countries within yourregion
Not enough time/resources to visit all
Select those with diverse markets
Representing different situations in theregion
Introduce the ICP work-programme tothe country colleagues
Tasks of the regionalcoordinatorTasks of the regionalcoordinator
The first country visits
General presentation of ICP - also to high levelstaff and other offices (ministries)
Intensive preparation of country colleagues (ICP)concerning requirements
Analysing existing information (CPI etc.)
Going over the future product basket together
Typical aims of the visitTypical aims of the visit

Identifying problematic areas
Going out on the market together
Common completion of SPDs
Establish a trusting work-relationship
Minimum stay for newcomer-countries: two week
Typical tasks during visitTypical tasks during visit

Fairly large country, diverse range ofconsumption goods and services on themarket
An „effective“ National Statistical Office,or NSI; published CPI, some NA available.

The outcome
SPD is not yet an item list
SPD is not yet a region‘s questionnaire
Each sheet refers to a CLUSTER (group of items)but is a combination of parameter „values“
Filter out single products (items)
Choose those variants which have been mostfrequently mentioned
Steps from the SPD to pre-survey questionnaire (1)Steps from the SPD to pre-survey questionnaire (1)
The outcome
SPD info is based on some countries only
Other countries should be confronted withconcrete item proposals
Other countries should give statements aboutavailability of proposed items ...
... and make additional proposals
