This 1977 paper is about estimating elasticities for the ORANI model -- in particular the elasticity of substitution between capital and labour. Literature is surveyed, and a theoretical approach outlined. Then data and regression results are briefly discussed. From cross-sectional data, the...

This 1978 paper is about modelling production input demands for the ORANI model. It examines a nested production structure where capital and labour are combined to form "value-added", which is in turn combined with a materials aggregate to form output. The nested production structure is...

This review of time series and cross-sectional studies indicates that there is little agreement as to the "true" value of the elasticity of substitution. There appears to be no clear-cut explanation for the diversity of the estimates. Not only do the various studies attribute widely different...
