thanks for this very interesting piece of work. Three quick comments/questions:
1) In difference to other similar studies your sample included only businesses that indicated an interest to expand their activities. Should a conclusion of practitioners like me be that we need to invest more time and effort into selecting and screening participants rather than relying that charging a fee for training offers will be a good filter?
2) Do you have also results for the effects of "training only" which is still a widely spread practice?
3) I understand your findings definitely as a call to move away from stand alone interventions and to offer packages of finance and training or technical assistance.
Best regards, Markus
