Comptes Harmonisés sur les Echanges et L’Economie Mondiale (CHELEM)

Harmonized data on trade, BOP and GDP. Update of trade and exchange rates (year 2015)

For several decades now, the CHELEM database [International trade flows, balances of payments and world revenues], developed by the CEPII, has been recognised as one of the most useful tools to analyse global economic trends in a framework combining coherence, exhaustiveness and reliability. The construction of such a database implies the need to continually adapt to new technologies, to the deep transformations linked to the global geopolitical context, and to changes which are introduced in national or international sources.

The CHELEM database is composed of three databases: CHELEM-International Trade, CHELEM-Gross Domestic Product and CHELEM-Balance of payments. These three databases contain annual data on long periods, going back to either 1960 or 1967. The three databases are interlinked by a common worldwide geographical classification organised in 95 elementary zones, one "miscellaneous" zone and one "total world", and by specific indicators.

 Methodology: a Short Description

The CHELEM - International Trade database (INT):

Contains the bilateral flow of all traded goods expressed in millions of current dollars since 1967. The data from the different sources are harmonised and rendered coherent in a framework spanning the entire world and all goods, detailed in either 71 INT-CHELEM product categories, 43 INT-GTAP categories or 147 INT-ISIC accounts, to which are added the non-ventilated product account and the total products. For each year and product category, the trade between different geographical zones (countries or group of countries) are therefore represented by a unique and harmonised matrix.
These data can be aggregated by production chains, by stages in the production process, by intermediate sections, by sectors or by technological levels. Geographical aggregates are also available.

The CHELEM - Gross Domestic Product database (GDP) :

Contains economic aggregates from 1960 on and spans the entire world, covering the 95 elementary zones and the 201 independent countries or statistical territories. The series relate to the Gross Domestic Product (GDP) expressed in millions of dollars and are presented in three different ways: In international value, i.e. by converting flows expressed in national prices by the current exchange rate; in international volume, i.e. by converting flows expressed in constant national prices in respect to the base year by the exchange rate corresponding to the base year (2011); in PPP volume, i.e. in a system where prices are constant through time and space, by converting flows expressed in constant national prices in respect to the base year (2011) by the rate corresponding to Purchasing Power Parity. These GDP series are complemented with total population series (millions of inhabitants at mid-year) and nominal exchange rate series for independent countries.

The CHELEM - Balance of Payments database (BOP)

Contains information on the flows of the Balance of Payments since 1967. This data covers the entire world and, hence, concerns 194 countries as well as the 95 elementary zones identified by the common classification and international organisations. They are displayed in a classification aggregated in 30 credit accounts, 30 debit accounts, 37 balance accounts and 7 specific balance accounts, presenting the main headings of the classification recommended by the International Monetary Fund in the sixth manual of the Balance of Payments of 2008.

This data, once completed and corrected, is expressed in millions of current dollars. The data used is essentially the primary data provided by the IMF.
