World Input-Output Database

From Open Risk Manual

Definition

The World Input-Output Database (WIOD) is an example of an Environmental Input-Output Database.

Structure

World Input-Output tables and underlying data, covering 43 countries, and a model for the rest of the world for 2000-2014. Data for 56 sectors are classified according to the International Standard Industrial Classification revision 4 (ISIC REV. 4).

Inter-country Supply-Use and Input-Output tables

  • Benchmarked to National Accounts data
  • 35 sectors (NACE Rev. 1) and 59 products (CPA)
  • Linked together with bilateral trade data for goods and services
  • 40 countries (85% of world GDP) + estimate for RoW
  • Period Covered: 1995-2009/2011 (current and previous year prices)


The WIOD MRIO includes 44 sectors. The newer classification ISIC rev. 4 is used in WIOD, but it has a rather aggregated industry classification. This is particularly true for the agriculture and energy-producing sectors, where detail is important when it comes to analysing issues related to land, water or resource use.

WIOD data cover 43 countries, including 28 EU countries and 15 other major countries. It also includes one residual region (Rest of World (RoW)) in which all other countries are aggregated. This is a limitation in terms of analysis by region for value added outside of the available countries.

The database covers 28 EU countries and 15 other major countries from 2000 to 2014. These countries represent approximately 85% of the world's gross domestic product. A Rest of World region is included for the remainder. The database provides an industry x industry IOT with a total of 56 sectors.

Satellite accounts

  • Socio-economic: Capital and labour (HS, MS, LS) in physical inputs and factor incomes
  • Environmental accounts (emissions, energy use, resource use)


History

A first version of the WIOD data set was released as part of the official WIOD project funded by the European Commission from 2009 to 2012. Large-scale EU Framework 7 project (May 2009 to April 2012)

The current version of the data set, “Release 2016”, was published in 2018, and includes an update of the MRIO table and the socio-economic accounts. However, the environmental accounts still refer to “Release 2013”.

Construction

The first release of WIOD (April 2012) contained world input-output tables (WIOTs) expressed in previous year’s prices (pyp). These WIOTs in pyp had been constructed using the well-known double- deflation method, in which value added figures by industry are obtained as residuals


Issues and Challenges

  • the data for specific countries deviates from the data within the national accounts of those countries. The harmonised version of Exiobase is referred to forthwith as SNAC Exiobase (Single-country National Accounts Consistent)
  • non-unique coupling with NACE
