This paper uses regional variation in labor markets, the industry structure and the educational system to explain the training decisions of firms. Using a representative firm-level data set, the results show that firms are less likely to offer training if the number of competing firms situated in the same geographical area is high. Furthermore, the supply of potential apprentices affects the training decision positively through an improved matching process. In addition, the expected ability of apprentices also has a positive impact, whereas a more developed system of full-time schooling options for school leavers reduces the likelihood of a firm to offer training.
