A Cross-Country Estimation of the Elasticity of Substitution between Labor and Capital in Manufacturing Industries
This paper presents a simple methodology to estimate the elasticity of substitution between labor and capital for firms operating in perfectly competitive markets with CRS production functions. It is applied in a cross-country sample to 28 3-digit ISIC manufacturing industries. The econometric procedure relies on measures of sectorial capital stock, that are estimated for a sample of more than 30 countries. Unlike older studies, the estimates are consistent with hicks-neutral cross-country technology differences. The results reveal that in most industries the elasticity of substitution is smaller than one, rejecting the null hypothesis of Cobb-Douglas production functions. The paper provides then an estimation of ¾LK at a level of aggregation extremely useful for research in the international trade literature.
