Tiivistelmä:This paper provides an empirical test of the particular product life-cycle hypothesis proposing that the firm size elasticity of process R&D exceeds the firm size elasticity of product R&D. Panel data on German manufacturing firms is used which is affected by attrition and sample selection. An inverse probability weighted generalized empirical likelihood (GEL) estimator is proposed vs. generalized method of moments (GMM) etc. In all specifications, the product life-cycle hypothesis is clearly rejected.
