Regional Input-Output Tables

Regional Input-Output Tables provide an extensive tool for economic analysis. These tables allow to deeply focus on selected regions and respect specific structural relationships rather than using national Input-Output tables. Regional models based on regional multipliers should provide better results that using national averages. Our estimates are based on multiregional model that provides appropriate detail of information with respect to necessary simplification. The process of compilation of regional Input-Output tables is usually demanding on data sources and costly and our papers describes own-developed procedures deriving regional tables and regional expenditure approach to gross domestic product. The key concept lies in the combination of existing input-output tables from national accounts with additional data from regional accounts and lots of auxiliary data sources. In the EU, information about regional value added is usually known but output and intermediate consumption have to be estimated, as well as inter-regional transactions. Finally, all the prepared regional input-output tables have to be balanced and they have to be fitted to national input-output tables.
