Thanks to a recent and vast empirical literature, we know in details how the most popular open source projects are organized and why they succeed. However, open source is not only Linux: in this paper we use a large data-set obtained from SourceForge.net to estimate the main determinants of the...

users to satisfy their specific needs; the more a software evolves towards a stable release able to address the requirements of its developers, the more successful the project. In this paper we use a large data-set obtained from SourceForge.net to estimate the impact of observed project...

Governments’ interest in Free/Open Source (F/OS) software is steadily increasing. Several policies aimed at supporting Free/Open Source (F/OS) software have been taken or are currently under discussion all around the world. In this paper, we review the basic (economic) rationales for such...

This paper analyses the impact of public policies supporting open source software (OSS). Users can be divided between those who know about the existence of OSS, the "informed" adopters, and the "uninformed" ones; the presence of uniformed users yields to market failures that justify government...

Dual licensing has proved to be a sustainable business model for various commercial software vendors employing open source strategies. In this paper we study the main characteristics of dual licensing and under which conditions it represents a profitable commercial strategy. We show that dual...

This text rigorously blends theory with real-world applications to study the industrial organisation of the ICT sector. Each of the self-contained chapters, which can be studied in isolation, contains theoretical models that are presented in a clear and accessible way. Throughout, a series of...

During the last few decades, the number of patents in information and communication technologies has increased considerably. An increasing number of patents and the associated fragmentation of IP rights have generated a series of potentially problematic consequences. Patent thickets, royalty...

This paper focuses on a specific strategy that developers of mobile applications may use to stimulate demand: the release of updates. We start with a stylised theoretical analysis to describe the developer's decision to release an update. Its predictions are then tested by using an unbalanced...
