In economic literature, some information deficiencies and computational complexities have traditionally been solved through the aggregation of data. In input--output (IO) modelling, researchers have been interested in aggregation since the 1950s. Extending the conventional IO aggregation...

<Para ID="Par1">The traditional literature to identify key sectors, based on an input–output demand-side approach, evaluates the impact on sectoral production of the exogenous inflows to activities. This approach has been the centre of an important debate, based on the lack of robustness of the results...</para>

Llop M. and Manresa A. (2007) Analysis of linear multipliers in an open regional economy, Regional Studies 41, 421-428. Since Round's pioneering contribution in 1985, the conventional approach for analysing the interdependences between economic systems involves multi-regional or multi-country...

This paper analyses the economic impact of alternative water policies implemented on the Spanish production system. The methodology comprises two versions of the input-output price model: an average cost formulation and a mark-up formulation. The input-output framework evaluates the impact of...

The complexity of the connections within an economic system can only be reliably reflected in academic research if powerful methods are used. Researchers have used structural path analysis (SPA) to capture not only the linkages within the production system but also the propagation of the effects...

The analysis of gas emissions by an input-output subsystem approach provides detailed insights into pollution generation in an economy, by revealing the channels by which the environmental burdens are caused and transmitted throughout the production system. In this paper we propose a...

The Water Framework Directive (WFD) defines common objectives for water resources throughout the European Union (EU). Given this general approach to water preservation and water policy, the objective of this paper is to analyse whether common patterns of water consumption exist within Europe. In...

The aim of this work is to investigate the direct and indirect effects of an environmental tax on Spanish products, based on their CO₂ emission intensities. For this purpose, we apply environmental input-output (EIO) and price models. The short-term price effects of the introduction of tax on...
