“…From an operational viewpoint, there is no reason at all why the explicit functional form of the underlying production function should be stated since its relevant parameters can be estimated from the cost function or in this case the input demand function which follows as the first derivative of the cost f~n c t i o n .~ In the approach that follows, the underlying production function is not specifled and estimation of the ES is undertaken directly from the factor demand equations which are formulated in a manner consistent with neo-classical theory. This approach is very similar to that adopted by Thirsk [25] in a study of factor substitution in Columbian agriculture. w e begin by specifying the n factor demand equations associated with the production function Y = f(XJ as:…”

Studies of the ease of substitution between inputs in production have generally been carried out Within a production framework of an explicit functional form. In this study, a somewhat different approach is followed. A model of derived demand for primary factors of production, land, labour and capital b formulated to enable inferences to be made about the characteristics of the unspecified production function. The model is used to obtain estimates of the pairwise Allen-Uzawa substitution elasticities which are secondary parameters of the underlying production function. The reported FIML estimates from aggregate time series data for the period 1920/21 to 1969/70 indicate very low and marginally different substitution elasticities between different pairs of factors, suggesting that both the Cobb-Douglas and CES production function specifications for the Australian agricultural sector are inappropriate.

“…Still, the degree of substitution may be higher for countries in earlier stages of economic development. For instance, findings based on farm level data from Colombia show that the elasticity of capital–labor substitution in agriculture is well above unity (Thirsk ). In light of these previous results, one could expect the elasticity between farm labor and machinery in Chinese agriculture to be fairly high.…”

The substitution between rural labor and machinery has been a key determinant of farm production, structure, and efficiency in most developed countries and is expected to play a key role in shaping the future of Chinese agriculture. Using disaggregated farm-level data from Hebei and Shandong provinces of China, we calculated the Allen and Morishima elasticities of substitution between labor and machinery. These elasticities were based on seemingly unrelated regressions and three-stage least squares estimates of the translog cost function and input cost share functions. In contrast to previous studies, we dissaggregate machinery inputs into three categories: large, medium, and small. In addition, the issue of endogeneity in output quantity and input prices is also addressed. The results show strong evidence of substitution between labor and the three categories of machinery inputs. The findings also support substitution among the three categories of machinery themselves. La substitution entre la main-d'oeuvre agricole et la machinerie constitue un déterminant fondamental de la production, de la structure et de l'efficacité des exploitations agricoles dans la plupart des pays développés et elle devrait jouer un rôle clé dans l'évolution de l'agriculture chinoise.À l'aide de données désagrégées sur les exploitations agricoles situées dans les provinces chinoises de Hebei et de Shandong, nous avons calculé lesélasticités de substitution d' Allen et de Morishima entre les facteurs de la main-d'oeuvre et de la machinerie. Le calcul de cesélasticités est basé sur des régressions apparemment indépendantes (SUR) et sur la minimisation des moindres carrés en troisétapes (3SLS). Contrairement auxétudes antérieures, nous avons subdivisé la machinerie en trois catégories : grosse, moyenne et petite. Nous avonségalement examiné l'endogénéité de la quantité d'extrants et des prix des intrants. Les résultats de notreétude illustrent clairement la substitution entre la main-d'oeuvre et les trois catégories de machinerie et appuient aussi la substitution entre les trois catégories de machinerie.
