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...

The biproportion of S on margins of M is called the intern composition law, K: (S,M) → X = K(S,M) / X = ASB. A and B are diagonal matrices, algorithmically computed, providing the respect of margins of M. Biproportion is an empirical concept. In this paper, we show that any algorithm used to...

This paper is a reply to Oosterhaven's reply of the paper A critical comment on Oosterhaven-Stelder net multipliers written by de Mesnard in this issue of The Annals of Regional Science. It is argued that, unlike Oosterhaven's statement, (1) any coefficient must be stable but Oosterhaven-Stelder...

Recently, Oosterhaven and Stelder (OS, 2002) have introduced the operational idea of a 'compensated net multiplier' (CNM) to take into account the double counting that occurs when output replaces final demand as an exogenous entry when the Leontief model is used to evaluate operationally the...

This research note demonstrates the advantage of biproportional projection over the ordinary (proportional) method of technical coefficients in input-output analysis: the former is insensitive to price changes, the latter is not so. Consequently, structural change can generally be measured using...

The Make-Use Model serves as a basis for most national accounting systems as the System of National Accounts (SNA) and is acknowledged as the most suitable model for interregional analysis. Two hypotheses are traditionally made featuring either industry-based technologies (IBT) or...

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...

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...

The principle of matrix adjustment methods consists into finding what is the matrix which is the closest to an initial matrix but with respect of the column and row sum totals of a second matrix. In order to help deciding which matrix-adjustment method is the better, the article returns to the...
