Measuring factor substitution and technological change in the Tunisian agricultural sector, 1971 - 2000 AgEcon
Lachaal, Lassaad; Chebil, Ali; Dhehibi, Boubaker.
The production structure of Tunisian agriculture over the last three decades is investigated using a translog variable cost function. Standard results of neoclassical duality theory are used to obtain measures of elasticities of substitution between inputs, price elasticities of factor demands and the rate of growth and bias of technological progress. Empirical results obtained from the joint estimation of parameters of the cost and share equations indicate an increasing trend in the degree of substitutability between labour and intermediate inputs. The own-price elasticities of labour and intermediate inputs are inelastic. While the labour price elasticity of demand has increased over time, the...

Technology, Trade, and Income Distribution in West Germany: A Factor-Share Analysis, 1976-1994 AgEcon
Ochsen, Carsten; Welsch, Heinz.
This paper examines the determinants of functional income distribution in West Germany. The approach is to estimate a complete system of factor share equations for low-skilled labor, high-skilled labor, capital, energy, and materials, taking account of biased technological progress and increasing trade-orientation. Technological progress is found to reduce the share of low-skilled labor and to raise the share of high-skilled labor. The effect of technology bias on the two labor shares is enhanced by substitution of intermediate inputs for lowskilled labor, which is almost absent in the case of high-skilled labor. Trade-induced changes in the composition of aggregate output tend to mitigate these effects, due to the relatively favorable export performance...
