This study examines whether staged project management is beneficial or harmful for making product innovations. Using a unique firm survey for Japan, we find that firms that employed staged project management had a higher likelihood of introducing new products to the market. Additional...

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...

It is known that small firms rely mainly on the CEO's individual knowledge for developing innovations. Recent work suggests that this approach is inefficient since it underutilizes other employees' knowledge. We study to which extent using CEOs, managers and non-managerial employees' ideas...

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...

This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated...

This paper analyzes the relationship between service innovation and different types of enterprise software systems, i.e. standardized enterprise software designed to fit one certain business sector and enterprise software specifically customized for a single firm. Using firm-level data of a...

This paper analyses the relationship between past innovation output, competition, and future innovation input in a dynamic econometric setting. We distinguish two dimensions of competition that correspond to the concepts of product substitutability and entry barriers due to fixed costs. Based on...

Economic theory suggests that financing constraints may occur due to capital market imperfections. These particularly affect investments in innovation projects as such projects are typically characterized by a high degree of uncertainty, complexity and specificity. Financing innovation...

The resource-based view of the firm is characterized by the idea that capital, labor and natural resources are the factors influencing the economic growth of a company. In the last decades, the awareness of knowledge as an important driver of economic growth has increased, and led to the...
