This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behaviour of firms once they are in the market. We adapt the Clark-Groves mechanism, characterize the optimal mechanism that maximizes the...

This article studies the design of optimal mechanisms to regulate entry in natural oligopoly markets, assuming the regulator is unable to control the behavior of firms once they are in the market. We adapt the Clark-Groves mechanism, characterize the optimal mechanism that maximizes the weighted...

After generics, which are copies of chemical medicines, "copies" of already patented biologics (biosimilars) are entering the biologics market and competing with their originators. Many uncertainties remain regarding the development of this newly emerging market, and the ability of biosimilars...

This paper addresses the question of what options are available to regulate the sector in the near future. In order to answer this question, the paper focuses on the problem of investment and innovation in an ex ante regulated sector. Relying on existing literature, we argue that ex ante...

In this dissertation, we analyze the social construction of a market of TV programs in Sub-Saharan Africa. Based on the study of a trade fair where buyers (TV channels, distribution intermediaries) and sellers of TV programs (studios, distributors and independent producers) can meet, negotiate,...
