a r t i c l e i n f o 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 that aim at endowing the linear models with additional general equilibrium feedbac...

This paper proposes a multiactivity generalisation of the Nelson–Winter model, or the NW model, in order to turn the attention of evolutionary minded economists toward specialisation and exchange, the emergence of markets for intermediate goods, the specialisation of R&D, and other issues of multisectoral growth and development. The argument and the solution is presented in four steps. First, t...

This note shows that Leontief's well-known demand-driven input–output (IO) quantity model may also be interpreted as the almost unknown revenue-pull IO price model, but measured in value terms instead of prices. It is shown how these two models combined into a single ultimate equation. An analogous result holds for supply-driven and cost-push which results The new interpretation Leontief opens ...

The paper investigates the implications of hedonic pricing of components, with an application to the dynamics of dairy product prices. A conceptual model of hedonic pricing is developed under a Leontief technology, showing how commodity prices reflect the underlying value of their components. Implications for the existence of cointegration relationships among commodity prices are derived. An ap...

We extend the analysis of [26] to handling more general utility functions: linear substitution functions, which include the Leontief utility. We show that the problem reduces to the general analytic center model discussed in [26]. Thus, the same complexity bound applies to approximating the Fisher equilibrium problem with linear substitution utilities. More importantly, we apply the model to sh...

In this paper 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 Leontief model and have been recently proposed in the Ghosh model. We detect that these rules may give rise in both models to some allegedly pathological behavior in the sense that sectoral or aggregate output, very often, may not fo...
