We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

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...

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...

International knowledge spillovers, especially through multinational companies (MNCs), have recently been a major topic of the academic and management discussion. However, most studies treat MNC subsidiaries as relatively passive actors without clear knowledge protection strategies. The goal of...

This study focuses on the early stages of international innovation activities, i.e. the organizational processes through which promising ideas from around the globe are collected and evaluated. We ask: What characteristics make foreign knowledge interesting to domestic Ramp;D managers? We...

Knowledge spillovers to competitors are regarded as an important aspect of the innovation process. While a company possibly benefits from incoming information on successful Ramp;D conducted by other companies, a generally high probability of leakage of knowledge in an industry will negatively...

Innovation success depends heavily on firm's ability to set priorities and select the most promising options from its project portfolio before the odds of success or failure become visible and reliable. We ask: What does previous innovation experience tell firms about what not to do in the...

Unique knowledge is a key factor for companies for generating new products, services and processes and thus, to remain competitive. It is increasingly emerging outside of firm boundaries. Universities and public research institutions have been identified as important sources of new knowledge....

The viability of modern open science norms and practices depend on public disclosure of new knowledge, methods, and materials. However, increasing industry funding of research can restrict the dissemination of results and materials. We show, through a survey sample of 837 German scientists in...

This paper analyzes the determinants of R&D co-operation among German manufacturing firms. Using firm level data from the Third Community Innovation Survey from Germany, we focus on the role of spillovers in explaining R&D cooperation. We also investigate firms' decisions to cooperate with...
