[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,...

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...

The French government plans to authorize a fourth operator to enter the country’s mobile phone market alongside Orange, SFR and Bouygues Telecom. While the French government sees this as a way to foster competition, this paper predicts the move will prove a disappointment. Three points are...

In the Supply-Use (or Make-Use) input-output model, “product-technology” (PT) or “fixed-industry-sales-structure” (FISS) assumptions are more widely adopted (SNA, Eurostat) for deriving symmetric input-output tables (SIOT) than “industry-technology” or...

We discuss each of the recommendations made by Hochberg et al. (2009) to prevent the “tragedy of the reviewer commons”. Having scientific journals share a common database of reviewers would be to recreate a bureaucratic organization, where extra-scientific considerations prevailed....
