Exports and Labour Demand

Abstract: To simplify the representation of a technological relationship between inputs and outputs, a production unit's technology must typically satisfy some restrictive conditions, some of them being well known in the literature. This article presents new results for aggregating labor inputs and outputs, in terms of restrictions on elasticities of scale and substitution. These conditions are then empirically investigated, in a framework that is flexible and does not lose its flexibility after separability being imposed. The empirical findings of the exact approach to aggregation are found to be rather pessimistic on the possibility of providing a simplified representation.
