Software is a potentially excludable public good. It is possible, at some cost, to exclude non-paying users from its consumption by using copyright law or technological restraints. Licensing the software under proprietary license terms makes of it a private good, licensing it under the BSD does...

The main argument of this paper is that consumption and demand, like production, are discovery processes guided by trial-and-error and learning by consuming. The key question that is addressed is: how do consumers deal with innovation? By bringing together a number of threads within the...

This paper studies vertical R&D spillovers between upstream and downstream firms. The model incorporates two vertically related industries, with horizontal spillovers within each industry and vertical spillovers between the two industries. Four types of R&D cooperation are studied: no...

Using a recently developed model which allows to separate a few well- established employment effects of product and process innovations, this paper reports new results on the relationship between innovation and employment growth in Germany. The model is tailor-made for analysing firm-level...

What determines the speed of the technology diffusion? What are the consequences of diffusion? This paper presents a model to address these questions. Skilled machine-users adopt a new technology first, while unskilled users wait until machines become more reliable and accessible. The quality...

This paper analyzes the effects of public subsidies on R&D expenditure in the German manufacturing sector. The focus is on the question whether public R&D funding stimulates or crowds out private investment. Cross sectional data at the firm level is used. By applying parametric and...

Endogenous growth theory is one of the mainstream economics approaches to modelling economic growth. This paper provides a non-technical overview of some key strands of the endogenous growth theory (EGT) literature, providing references to key articles and texts. The intended audience is policy...

This paper examines whether patenting increases the private incentives to innovate in manufacturing. To study this issue, we build a model in which the value of an innovation depends both on the type of innovation implemented (product, process) and on the existence of a patent protection or not....
