We investigate the impact of different types of training on the mobility ex
pectations of workers, using three surveys. Most training episodes produce
some transferable skills, and most transferable training is paid for by emp
loyers. Overall, training has no impact on mobility in three out of every f
ive cases, the remaining cases are split equally between those where traini
ng increases and those where it decreases mobility. We find that training i
s more likely to lead to lower mobility when it is less transferable to oth
er firms, is sponsored by firms, and where its objectives include increasin
g the identification of employees with corporate objectives.
