In this article, I explore the effect of training on the productivity of a sample of Italian firms and the impact of training on EU economic growth. Specifically, retrieving data from a survey performed by the Italian Institute for the Development of Vocational Training in 2009, I find that employer-sponsored training displays a positive and significant effect on the main corporate performance indexes. However, in comparison with companion longitudinal evidence, the magnitude of this impact appears quite narrow. Untangling the determinants of training provision at the firm level and exploring the consequences of training on growth rates by means of the EU's Continuous Vocational Training Survey 4 records, I show that this finding is the outcome of microeconomic and macroeconomic size effects that influence, respectively, the identification of the training impact on corporate productivity and the aggregate performance of the whole economy.
