Handbook on Extended Supply and Use Tables and Extended Input-Output Tables

This Handbook is a step bridging the gap between macroeconomic (national accounts) and microeconomic (business statistics and trade statistics, at enterprise level or by type of enterprise). It provides methodological guidance to combine the strengths of both. The macroeconomic statistics relate to GDP and employment, and they are internally consistent. They are also complete, containing estimates for difficult to survey production such as some activities of micro enterprises and illegal activities. The microeconomic statistics provide a wealth of detail, with all kinds of types of enterprises such as small- and medium sized enterprises, multinationals, and exporters/non-exporters that policymakers are interested in. Combining macroeconomic and microeconomic statistics has many benefits. It relates production, value added, imports, and exports of types of enterprises to GDP, total employment and other macroeconomic data in a proper way. It adds heterogeneity to statistics and indicators such as the domestic value added content of exports. This is desirable, since the aggregate might mask important information related to the diversity of the components. It also provides new indicators about direct and indirect linkages, of types of enterprises with each other and of types of enterprises with foreign and domestic supply and use. For example, it is well-known that SMEs generally have a lower propensity to export than large enterprises. The new information shows that due to their sizeable indirect exports, supplying large exporters with goods and services, SMEs still benefit from foreign markets.
