In general terms, key sectors analysis aims at identifying and quantifying the economic impact of a sector in a given economy. For a sector, we mean here either an industry or a region, or even a cluster of them. Quite a few measures and methodologies of varied complexity have been proposed in...

We explain in this work why a straight calibration to published input-output or SAM data in multisectoral modelling may lead to the use of an incorrect representation of the productive technology, hence casting doubts on the value of the empirical results. The culprit is the possible presence of...

This year marks the 25th anniversary of the International Input--Output Association and the 25th volume of <italic>Economic Systems Research</italic>. To celebrate this anniversary, a group of eight experts provide their views on the future of input--output. Looking forward, they foresee progress in terms of...

We reconsider in this paper the alleged implausibility of Ghosh's model and we do so reformulating the model to incorporate an alternative closure rule. Our proposed closure rule is in line with the original allocation rules defined by A. Ghosh. The closure solves, to some extent, the...

We explore the sectoral and aggregate implications of some endogeneization rules (i.e. on value-added and final demand) which have been common in the extended demand-driven Leontief model and have been recently proposed in the supply-driven Ghosh model. Extended linear models are refinements...

We develop a scale-dependent nonlinear input–output model which is a practical alternative to the conventional linear counterpart. The model contemplates the possibility of different assumptions on returns to scale and is calibrated in a simple manner that closely resembles the usual technical...

This paper proposes a new approach to measure the impact of a sector's price shock on price indices. It works based on table adjustments to trace the effects of any initial price shock through an iteration process. It has the same accuracy and all the capabilities of the popular Standard...
