This paper introduces the rest of this issue, which is dedicated to the contributions of Sir Richard Stone, Michael Bacharach, and Philip Israilevich. It starts out with a brief history of biproportional techniques and related matrix balancing algorithms. We then discuss the RAS algorithm...

[fre] On répond ici aux partisans du rejet du modèle d'offre dominante en analyse input-output et en particulier à A. Torre (Revue économique, 5 (44), p. 951-970). Tout d'abord les hypothèses de demande dominante (Leontief) et d'offre domi­nante (Ghosh) sont symétriques et incompatibles,...

Two elements are being presented in this paper: (1) A new and original method for analyzing matrix dynamics, called the synthetical biproportional projector method (SBP), which can be used to project input-output tables and compare one with another. (2) Some results for France for the important...

The traditional dynamic Leontief model is synchronous: every vertex acts simultaneously. A model with delays of action has been proposed, but it still remains synchronous. In this paper the author proposes an asynchronous version of the model that allows realistic computations. He furnishes an...

The paper discusses qualitative input-output methods. It is shown that information is lost. Because the binary relation constructed by qualitative methods is not transitive, the model lacks economic consistency. Qualitative methods are tending to become more sophisticated, but some problems of...

The method of forecast output coincidence used to determine if sectors are demandsided or supply-sided in an input-output framework mixes two effects, the structural effect (choosing between demand and supply side models) and the effect of an exogenous factor (final demand or added-value). The...

France Telecom (FT), SFR and Bouygues Telecom (BT) have been fined by France's Conseil de la Concurrence (CC) for organizing a mobile phone cartel with stable market shares (one-half, one-third and one-sixth respectively) and for directly exchanging commercial information. While not contesting...

Net multipliers, as introduced by Oosterhaven and Stelder (2002) accept outputs as entries instead of final demand. They are found by multiplying ordinary multipliers by the final demand ratio over the sector's output. This pragmatic solution suffers from ratio instability over time. The...
