This paper covers network investment problems under decentralized control of regulation, infrastructure ownership and management. The model features two countries managing domestic infrastructures, used simultaneously for downstream international service provision. Initially, the welfare losses...

Abstract We study the welfare impact of revenue management, a practice which is widely spread in the transport industry, but whose impact on consumer surplus remains unclear. We develop a theoretical model of revenue management allowing for heterogeneity in product characteristics, capacity...

This paper analyzes the relationship between a national regulator, an incumbent and a local government in a context where investment in a new network has to be undertaken. In the light of the recent debates on the competition between private firms and local governments, we analyze the limits to...

Most digital goods have a modular design; that is, they consist of complementary and distinct building blocks, called modules. Modular product design, in contrast to integrated (or integral) design, enables alteration of a specific module that is usually assigned for a specific function without...

We consider an unregulated incumbent who owns a broadband infrastructure and decides on how much access to provide to a potential entrant. The level of access determines the amount of investment the entrant needs to undertake to enter the market, and the intensity of post-entry competition. We...

Abstract In this paper, we analyze the impact of cooperation on R&D investments in a two-sided market, where platforms compete in quantities. We show that if indirect externalities are of a moderate magnitude, the threshold degree of spillovers above which cooperation spurs R&D investments and...

Abstract In this paper we propose a model where consumer personal data have multidimensional characteristics, and are used by platforms to offer ad slots with better targeting possibilities to a market of differentiated advertisers through real-time auctions. A platform controls the amount of...
