Introduction
• The Joint System’s Features
– collection and sharing of detailed annual commodity-by-partner trade data
– common data-processing standards
– computer applications for use in data-processing and dissemination

Joint System Objectives• Reduce national authorities’ response burden• Synchronize and harmonize data-processing
routines• Disseminate identical high quality detailed
international merchandise trade data
• The organizations’ databases will be coherent
and consistent • Best use will be made of scarce resources

Background• Separate/independent data collection,
processing and publishing activities at OECD and UNSD; discrepancies appeared from time to time in published data
• Suspicions confirmed: countries sometimes sent different data to each
• Conclusion: reconciling OECD and UNSD data only possible using same data sets and processing procedures

From the early 90s to 1998, what took so long?
• Preferences - UNSD disseminated provisional as well as final data; OECD only final data
• Treatment of confidential data
• Different country codes being used
• Conversion of commodity classifications

Data collection: the first step
• 2001 Memorandum of Understanding– OECD will collect trade data and metadata
from its member countries
– UNSD will collect from non-OECD countries only
– OECD will share the data with UNSD
![Page 7: UN / OECD JOINT SYSTEM FOR THE COLLECTION AND PROCESSING OF INTERNATIONAL MERCHANDISE TRADE STATISTICS Mary Jane Holupka, United Nations Statistics Division.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bfc01a28abf838ca3902/html5/thumbnails/7.jpg)

IT Developments taking place at the same time
• A move away from mainframe to server environment – OECD chose Oracle database in 90s, then
shared this knowledge with UNSD in 2000
– In 2001, UNSD switched to SQL-Server, then shared this knowledge with OECD in 2003

The development of the UN/OECD Joint System
• Common data-processing standards for: – country codes– trade conversion factors– classifications and correlation tables– non-standard codes– quantity units and quantity estimations– confidentiality– metadata– synchronization of databases
![Page 9: UN / OECD JOINT SYSTEM FOR THE COLLECTION AND PROCESSING OF INTERNATIONAL MERCHANDISE TRADE STATISTICS Mary Jane Holupka, United Nations Statistics Division.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bfc01a28abf838ca3902/html5/thumbnails/9.jpg)

The development of the UN/OECD Joint System (cont.)
• All computer applications for processing and dissemination of trade data are to be shared
• Starting point – UN Comtrade, installed by OECD and made accessible to public by mid-2006
• COPRA (Commodity Processing application) as a foundation, with the following benefits:– inter-agency standards on all details of data processing– harmonization of published international trade statistics– higher level of data quality– full accountability in the treatment of trade data– availability of a complete set of metadata

Data Dissemination
• Both organizations will continue to keep separate international merchandise trade statistics databases, to serve their own particular needs:– storing various data in addition to those agreed in the Joint
System (e.g. historical data, memorandum items, derived data, etc.)
– developing additional analytical and presentational functionalities and controlling user access to them
– dissemination practices, including pricing of user access to the database services, entering into contracts with users
• Disclaimers to alert the user to common standards and compliance with the Data Sharing Agreement

The Current Situation
• Starting with 2002 data, only OECD collects trade data from the OECD member countries, reducing the countries’ response burden
• As of 1 January 2006, the UN/OECD data-processing system has been operational, being fine-tuned. Will result in– higher quality trade statistics through an
improved data-processing system certified by UNSD and OECD
– higher quality dissemination system maintained by the combined team of UNSD and OECD IT experts
![Page 13: UN / OECD JOINT SYSTEM FOR THE COLLECTION AND PROCESSING OF INTERNATIONAL MERCHANDISE TRADE STATISTICS Mary Jane Holupka, United Nations Statistics Division.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bfc01a28abf838ca3902/html5/thumbnails/13.jpg)

The Current Situation (cont.)
• OECD web client being tested, when completed will have the same functionalities, look and feel as Comtrade. To “go live” by summer 2006
• Both UN and OECD logos to emphasize the inter-agency cooperation
• UN/OECD Joint System as a continuous effort– statisticians are constantly comparing notes and
finding solutions to details on data processing– IT experts are regularly crossing the Atlantic to
actively work on the data-processing system
![Page 14: UN / OECD JOINT SYSTEM FOR THE COLLECTION AND PROCESSING OF INTERNATIONAL MERCHANDISE TRADE STATISTICS Mary Jane Holupka, United Nations Statistics Division.](https://reader035.fdocuments.net/reader035/viewer/2022062805/5697bfc01a28abf838ca3902/html5/thumbnails/14.jpg)

Plans for further cooperation
• Development of a common strategy for maintenance and dissemination of the tariff-line data
• Evaluation of the possibility of collecting, processing and disseminating trade data containing additional features – mode of transport– nature of transaction– additional partner country attributions
• Further standardization and enhancement of the metadata
• Evaluation of the experience gained for use in similar activities in statistics of international trade in services
