A canonical Cournot competition model shows that the profitability of training can increase as the number of competitors decreases. British establishment evidence from 1998, 2004, and 2011 confirms that firms in less competitive markets provide more formal training. This persists within three separate cross‐sections and in two separate panel estimates. It persists with alternative measures of training, with alternative measures of market competition and in estimates designed to account for endogeneity. These results suggest that a dominant product market position, indeed, increases the incentives to invest in training.
