World Input-Output Database Environmental Accounts

This report describes the approach adopted for the update of the World Input-Output Database (WIOD) environmental accounts for the period 2000-2016. In constructing the WIOD-based energy and emission accounts we follow closely the methodology developed by Genty et al. (2012), with some adjustments due to changes in system boundaries, which are further detailed. This report illustrates the data adjustment steps required to reconcile energy and economic data which stem, for example, from different accounting principles. Special care has been taken to address problems related to time series breaks in order to achieve a smooth transition between the years 2009 and 2010 at the intersection between the original and new WIOD releases. Results for EU countries are compared with other data sources such as the previous WIOD time series, the Physical Energy Flows Accounts (PEFA) and the National Accounts Matrices with Environmental Extensions (NAMEA) showing a satisfactory goodness of fit, with some exceptions. A final comparison of the inter-temporal structure across periods is proposed in order to identify possible reasons of changes in the patterns of gross energy use.JRC.B.5-Circular Economy and Industrial Leadershi

FIDELIO 3 manual: Equations and data sources

FIDELIO (Fully Interregional Dynamic Econometric Long-term Input-Output) is a multi-sectoral model developed by the unit B.5 of the Directorate General Joint Research Centre (JRC) — the circular economy and industrial leadership unit. Compared to neoclassical CGE models — which assume that the perfect flexibility of prices and quantities ensures the full use of the factors of production at all times — FIDELIO integrates some new-Keynesian features: consumption adjusts slowly to its optimal level according to an error correction model and wages do not clear the labour market. The assumptions that prices do not clear the markets and market "imperfections" exist generate the dynamics of the model that is solved sequentially (recursive dynamic). In addition, FIDELIO is an econometric model since the calibration of most of the behavioural parameters of the model (dynamic adjustment lags of prices and quantities, and elasticities) is based on econometric estimations. This technical report illustrates the third version of the FIDELIO model, FIDELIO 3. The changes introduced in the subsequent versions of the model have two main objectives. The first one is to increase the coverage of the model. The second one is to improve the efficiency and the capacity of the model to evaluate sustainable production and consumption policies. The aim of this report is twofold. First, it contains all the equations of the current version of the model; second, it illustrates the characteristics of the data used by FIDELIO 3.JRC.B.5-Circular Economy and Industrial Leadershi
