This paper presents a model of private bilateral and multilateral peering arrangements between Internet backbone providers when the network is congested. We study how different forms of interconnection and the competitive conditions of the market affect backbones' investments in network and...

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...

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...

In this paper we study how the migration from an old to a new technology is affected by the access price to the old technology, when it is set after investments have taken place. We show that both the incumbent and the regulator are willing to set a very high access price to accelerate...

The theoretical literature on the cumulative innovation process has emphasized the role of ex-ante licensing – namely, licensing agreements negotiated before the follow-on innovator has sunk its R&D investment – in mitigating the risk of hold-up of future innovations. In this paper, we...

In this paper we present a theoretical model to study the characteristics and the commercial sustainability of dual licensing, an open source (OS) business strategy that has gained popularity among software vendors. With dual licensing, a firm releases the same software product under both a...

This paper presents a model of competition between an incumbent and an entrant firm in telecommunications. The entrant has the option to enter the market with or without having preliminary invested in its own infrastructure; in case of facility based entry, the entrant has also the option to...

We study the strategic choice of compatibility between two initially incompatible software packages in a two-stage game by an incumbent and an entrant firm. Consumers enjoy network externality in consumption and maximise expected surplus over the two periods. Compatibility may be achieved by...
