Does access to information and communication technologies (ICT) increase innovation? We examine this question by exploiting the staggered adoption of BITNET across U.S. universities in the 1980s. BITNET, an early version of the Internet, enabled e-mail-based knowledge exchange and collaboration...

In recent years, innovation processes involve more heterogenous actors inside and outside the firm. Little is known however about the spatial impact of this organisational decomposition of innovation processes (ODIP): Does it lead to a geographical dispersion of innovation activities as well?...

The Entrepreneurial University is a failed idea. This is not to disparage the entrepreneurial activities of faculty, graduates and students. Neither is it to criticise industry sponsored research and co-authorship. University research and higher education have a role in innovation. However, if...

This essay argues that the most crucial institution of any school system is its view of knowledge - from which virtually all other aspects of a school are derived: the content of its curricula, its pedagogical practices, and the incentives that motivate its members.

Are there positive or negative externalities in knowledge production? We analyze whether current contributions to knowledge production increase or decrease the future growth of knowledge. To assess this, we use a randomized field experiment that added content to some pages in Wikipedia while...

Do contributions to online content platforms induce a feedback loop of ever more user-generated content or will they discourage future contributions? To assess this, we use a randomized field experiment which added content to some pages in Wikipedia while leaving similar pages unchanged. We find...

Economic literature acknowledges the impact of immigration on cross-border patenting and scientific publications. However, the role of immigration ows in the dissemination of knowledge in a broader sense is yet to be assessed. In this paper, I estimate the effect of immigration on the...

Do contributions to online content platforms induce a feedback loop of ever more user-generated content or will they discourage future contributions? To assess this, we use a randomized field experiment which added content to some pages in Wikipedia while leaving similar pages unchanged. We find...

The paradigm of the mobile ecosystem is rapidly changing, especially since the introduction of smart devices. New important players are emerging, and the scope of the mobile ecosystem is expanding and encroaching on the technological boundaries of other IT ecosystems. However, our understanding...

The Internet is receiving increasing attention as a medium for technology transfer between public research and the enterprise sector. Based on a survey of public research units in natural sciences and engineering in Germany, we analyse the determinants of firm contacts established via the...
