Using patent data from 66 countries for the period 1990-2003, we characterize the factors which promote or hinder the international diffusion of climate-friendly technologies on a global scale. Regression results show that technology-specific capabilities of the recipient countries are...

In sectors with cumulative and complementry technologies, some firms build patent portfolios in order to block their competitors' access to the technology and/or to negociate cross licensing agreements. We propose a dynamic model that captures this behaviour in an integrated duopoly where the...

The Clean Development Mechanism (CDM) is expected to stimulate the North-South transfer of climate-friendly technologies. This paper provides an assessment of the technology transfers that take place through the CDM using a unique data set of 644 registered projects. It provides a detailed...

In this paper, we consider two platforms that compete for the development of a new product to integrate into their ecosystems. The new product can be developed either inhouse by the platforms or by an independent startup active only in the technology market. The presence of the startup affects...

Platform interoperability is considered a powerful tool to promote competition in digital markets when network effects are at play. We study the effect of interoperability on competition between two ad-financed platforms, allowing for endogenous multi-homing of consumers. When the platforms are...

In this paper, we evaluate the efficiency of the French State aid plan for broadband deployment, the Plan France Très Haut Débit. According to State aid rules, public subsidies should not be substitute for private investment and should target areas with market failures. We estimate a...

We introduce a model of asymmetric competition where two network operators with different investment costs may build an internet access infrastructure and where a virtual operator provides services through third-party access. We show that the virtual operator requests access from the low cost...

We consider a streaming platform which carries content from various upstream content providers. Participating customers face personalized recommendations from the platform and consume a mix of content originating from each provider. We analyze when the platform uses its personalized...

The emergence of online providers aggregating illegal content from streaming platforms is rekindling the debate about online piracy. In the past, the discussion mainly focused on the impact of piracy in content industries and the effect of anti-piracy measures. But little is known about one...
