The price-iso return locus for a regulated multiproduct firm shows all price vectors giving the rate of return permitted by regulation. The locus for any two products is shown to have both negatively and positively sloping segments. A price vector on a positively sloped segment is socially...

In the literature, the construction of technical coefficients is linked to flow data (use and make matrices), but stochastics are imposed on the coefficients when multipliers are calculated, by means of the Leontief inverse. Due the nonlinearity of this operation, the multiplier estimates are...

Sharkey has conjectured that for a natural monopoly: (1) the core price vector of some output vector (which renders any partial supply of the output unprofitable) lies on the demand curve; and (2) such a price vector is sustainable, meaning that supply by an entrant would be unprofitable, even at...

Kop Jansen and ten Raa (1990) established a purely theoretical solution to the problem of selecting a model for the construction of coefficients on the basis of make and use tables. In an axiomatic context, they singled out the so-called commodity technology model as the best one according to...

Presumably, input-output coefficients reflect technology, and these coefficients measure the input requirements per unit of product. This concept has been extended to consumption theory, where it models expenditure shares. Input-output coefficients are extracted from the national accounts of an...

How would competitive pressure impact upon the income distribution and the poverty of household groups? We analyse the gains in efficiency and productivity due to competitive pressure, and its distributional effects using a general equilibrium input-output framework. Efficient utilization of the...
