Hi friends One month ago I havve started an engineering course part time, a dream come true , with your continuous help I found the courage to attend this type of course and I making my wilful effort to success in this challenge. I have started programming and entrepreneurship, with the latter I am reading a book Democratizing Innovation by Eric Von Hippel, that can be found easily on Google. I have been stuck on chapter 8, page 110 about a quoted text as shown below, I need your precious help to clarify regarding this thanks SM We found that the addition of innovation by users to these analyses largely avoids the welfare-reducing biases that had been identified. For example, consider “business stealing” (Spence 1976). This term refers to the fact that commercial manufacturers benefit by diverting business from their competitors. Since they do not take this negative externality into account, their private gain from introducing new products exceeds society’s total gain, tilting the balance toward overprovision of variety. In contrast, a freely revealed user innovation may also reduce incumbents’ business, but not to the innovator’s benefit. Hence, innovation incentives are not socially excessive.
