In the traditional new product development process, manufacturers first explore user needs and then develop responsive products. Developing an accurate understanding of a user need is not simple or fast or cheap, however. As a result, the traditional approach is coming under increasing strain as...

The "lead user construct" was developed to preferentially identify commercially attractive innovation-related information developed by users of products and services. In this research, we use data drawn from users of Apache, an open source software project, to assess the association between each...

It is known that end users of products and services sometimes innovate, and that innovations developed by users sometimes become the basis for important new-commercial products and services. It has also been argued and to some extent shown that such innovations will be found concentrated in a...

In a first survey of its type, we measure development and modification of consumer products by product users in a representative sample of 1,173 UK consumers aged 18 and over. We estimate this previously unmeasured type of innovation to be quite large: 6.1% of UK consumers – nearly 2.9 million...

The impact of user innovation on social welfare isanalyzed by comparing user innovators to manufacturer innovators in terms oftheir innovation incentives and knowledge.Following a review of theliterature on product development by users, it is argued that the introductionof user innovation in a...

In this book I integrate new theory and new research findings into the framework of a “free innovation paradigm.” Free innovation involves innovations developed and given away by consumers as a “free good,” with resulting improvements in social welfare. I explain that free innovation is...

The literature on new goods and social welfare generally assumes that innovations are developed by manufacturers. But innovation by users has been found to also be an important part of innovative activity in the economy. In this paper we explore the impact of users as a source of innovation on...
