In this article, I derive expressions for the Morishima elasticities of substitution (MES) for the variable profit function and estimate these elasticities to shed some light on the substitutability between imports, capital services, and labor services. The results reveal that capital services...

Different types of labor and capital inputs have varying productive contributions that are dependent on plant characteristics. We estimate such contributions and their underlying determinants, recognizing the interactions among labor and capital components that reflect their substitutability or...
