Multiplier analysis based upon the information contained in Leontief's inverse is undoubtedly part of the core of the input-output methodology and numerous applications an extensions have been developed that exploit its informational content. Nonetheless there are some implicit theoretical...

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...

An extension of the hypothetical extraction method to a general equilibrium setting is considered. This has the advantage of re-interpreting output changes as efficiency gains or losses, which may be of use in identifying “key” sectors in an interconnected economy. The categorization may be...

Recently there has been a renewed research interest in the properties of non-survey updates of input-output tables and social accounting matrices (SAM). Along with the well-known scaling RAS method, new procedures related to entropy minimization and other metrics have been suggested, tested, and...

This paper explores the capacity of computable general equilibrium (CGE) models to track down policy induced economic changes and their ability to generate contrastable data for an economy. Starting from an empirically built regional Social Accounting Matrix (SAM), a first stage CGE calibrated...

We show that standard expenditure multipliers capture economy-wide effects of new government projects only when financing constraints are not binding. In actual policy making, however, new projects usually need financing. Under liquidity constraints, new projects are subject to two opposite...

Joint-stability in inter-industry models relates to the mutual simultaneous consistency of the demand-driven and supply-driven models of Leontief and Ghosh, respectively. Previous work has claimed joint-stability to be an acceptable assumption from the empirical viewpoint, provided only small...

From the classical gold standard up to the current ERM2 arrangement of the European Union, target zones have been a widely used exchange regime in contemporary history. This paper presents a benchmark model that rationalizes the choice of target zones over the rest of regimes: the fixed rate,...

In spite of having been first introduced in the last half of the ninetieth century, the debate about the possible rebound effects from energy efficiency improvements is still an open question in the economic literature. This paper contributes to the existing research on this issue proposing an...

Ghoshs model is discussed in this paper under two alternative scenarios. In an open version we compare it with Leontiefs model and prove that they reduce to each other under some specific productive conditions. We then move onto reconsidering Ghoshs model alleged implausibility and we do so...
