  1. Latin America Progress Report Presented to the World Bank Regional Workshop 13 September 2005

  2. Participating countries • 10 South American countries grouped into two sub-regions : • The Community of Andean Countries : (Bolivia, Colombia, Ecuador, Peru and Venezuela) • Mercosur and Chile : ( Argentina, Brazil, Chile, Paraguay and Uruguay) • 2 Ring countries : (Brazil and Chile)

  3. How • Because of scarcity of resources the ICP draws heavily on national CPI operations for: • Sample of outlets • Product specifications • Price collection operations • Computation and editing of prices • Ecuador, Uruguay, Chile and Colombia received additional funding for the ICP from their Central Bank • In Paraguay and Venezuela: Central Bank does CPI • Argentina, and Brazil received moral support (!)

  4. Coverage (1) • The CPI coverage is urban areas for all countries. • Brazil covers 6 main regions • In Argentina, Paraguay and Venezuela, price collection is limited to the Capital. • The ICP coverage is total GDP for all 10 countries.

  5. Coverage (2) • Andean Countries • Bolivia (4 cities) • Peru (5 cities) • Colombia (4 cities) • Ecuador (2 cities) • Venezuela (Caracas )

  6. Coverage (3) • Mercosur y Chile • Argentina (Buenos Aires ,+) • Brazil (6 regions) • Chile (13 cities) • Uruguay (5 cities) • Paraguay (Asunción)

  7. Data Collection • Collection for the ICP is conducted during a period of 4 to 6 weeks for each quarter. • The period is the same for all countries • The minimum period is 4 weeks but a country may decide to stretch it to 6 weeks. • In June only one country was using the Tool Pack PCM for Price collection (Uruguay)

  8. Summary: Number of Products

  9. Data operations (1) • Data are first edited by individual countries using either their CPI edit tools or Tool Pack • Micro data with the exception of the name of the outlet are sent to Statistics Canada for a second edit and quality control . • Formal agreements were signed between STC and each participating country to authorize the transfer of data to STC.

  10. Data operations • STC calculates averages and dispersion measures. STC also calculates the QT. • STC send back the aggregated data and QT to participating countries and ECLAC for further data confrontation. • Every country receive the average prices and PPPs of all other participating countries. Not the micro data.

  11. Review process • Errors and outliers are discussed one on one with the national coordinators before regional meeting with participating countries. • After each collection period, a regional meeting is held to discuss the preliminary results. • Review of errors (in group) • Review of problematic specifications (in group) • Individual review of country’s data • At the last two meetings : May 2005 and August 2005 Quaranta tables were used for the review

  12. Operational procedures (1) • Detailed and complete time-table has been established and agreed with all 10 countries for four quarters of 2005. • Weekly teleconference between the regional coordinators to monitor the project. • Weekly contacts with national coordinators • Country Desk: each member of the team is responsible for a set of countries

  13. Operational procedures (2) • For the two first quarter, field visits were done to assist countries before and during price collection • This quarter, limited assistance for collection is provided for a few countries. • In October 2005, before the price collection of the fourth quarter, a review and evaluation will be done in key countries to assure comparability.

  14. Meetings • Four regional meetings to discuss results of quarterly price collection with price and SNA experts: • May 2005 • August 2005 • November 2005 • April 2006

  15. Problems • Too few product specifications in some basic headings • Too few price collected • Too few outlets • Errors in collection (does not meet spec) • Errors in capture of data • Errors in unit of measure, etc • Toolpack

  16. Problems (2) • Problems in individual countries: • Strike in Brazil • Changes of government in Bolivia, Ecuador • Sharp reduction of staff in Venezuela • Problems of resources in Uruguay, Argentina and Paraguay

  17. Solutions • Reduction of scope for third quarter • Special collections in July and August to adjust second quarter • Re-inforcing the quality assurance of micro-data in countries • Mission of evaluation in October in key countries • Maintain tight timetable

  18. Example of timetable: 2st Quarter 2005 • Field Visits to countries : 1 May - 30 June • Colombia, and Ecuador (3) • Price collection: 15 May – 30 June • Preparation of micro data: 1- 12 July • Transmission of Food components :12 July • Transmission of rest of basket :18 July • Edit and aggregation at STC: 18 - 29 July • Transmission of aggregates : 3 August

  19. Example of timetable: 2st Quarter 2005 (2) • Regional meeting in Montevideo for revision of 2st Q of 2005 • Mercosur & Chile : 8 -11 August • Andean community : 12 -16 August • SNA experts: 8 -10 August • 3nd Q price collection : 15 August – 30 September

  20. Example of timetable: 2st Quarter 2005 • Regional meeting in Montevideo with national accountants for: • Discussion of March’s PPP • Preparation of consumption weights • Methodology of construction, M&E and government • Establishment of timetable for deliverable

  21. Timetable for Consumption • Fourth quarter price collection: 1 nov- 15 dec 2005 • Revision of 4th Q : Jan-Feb 2006 • Aggregation of 2005 : March 2006 • ECLAC-STC review of 2005 : mid March 2006 • Final review by all countries : 3-7 April 2006 • Preliminary publication of consumption: June 2006 • Ring: Chile (March-April 2006) Brazil (May 2006)

  22. Timetable for GDP • Revised GDP weights from SNA : 30 sept • Videoconference : 12 Oct 2005 • Establishment of criteria for the concordance between national and ICP classifications • Price collection for: • construction : nov 05 - jan 06 • machinery and equipment : dec 05 – feb 06 • Government : nov 05 – march 06 • Review of data : May-August • Publication of total GDP 2006 : December 2006

  23. Plans • Calculate an average of 4 quarters for all countries when possible • Aggregation procedures • Analysis of the data (by outlets, districts) • Price collection for construction, M&E and Government ( 4th Q 2005 and 1st 2006) • Ring (2nd Q of 2006) • Publication of consumption : June 2006 • Publication of GDP : Dec 2006
