Statistical indicators have not kept pace with innovation research. Today, it is wellunderstood that many industrial and consumer products are developed by users, and thatmany innovations developed at private cost are freely shared. New statistical indicatorswill empower policymakers to take...

The literature on new goods and social welfare generally assumes that manufacturers develop innovations. 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 product...

Almost 30 years ago, researchers began a systematic study of innovation by end users and user firms. At that time, the phenomenon was generally regarded as a minor oddity. Today, it is clear that innovation by users, generally openly shared, is a very powerful and general phenomenon. It is...

To solve a problem, needed information and problem-solving capabilities must be brought together. Often the information used in technical problem solving is costly to acquire, transfer, and use in a new location---is, in our terms, "sticky." In this paper we explore the impact of information...

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...

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 age 18 and older. We estimate this previously unmeasured type of household sector innovation to be quite large: 6.1% of UK...
