The World Wide Web was originally a totally English-based medium due to its US origin. Although the presence of other languages has steadily risen, content in English is still dominant, which raises a natural question of how bilingualism of consumers of a home country affects production of web...

This Paper models aid agencies as financial intermediaries that do not make a financial return to depositors, since the depositors' concern is to transfer resources to investor-beneficiaries. This leads to a significant problem of verification of the agencies' activities. One solution to this...

Sports organizations, Hollywood studios and TV channels grant satellite and cable networks exclusive rights to televise their matches, movies and media contents. Exclusive distribution prevents viewers from watching attractive programs, and reduces the TV-distributors incentives to compete in...

In many markets, such as education, health care and public utilities, firms are often profit-constrained either due to regulation or because they have non-profit status. At the same time such firms might have altruistic concerns towards consumers. In this paper we study semi-altruistic firms’...

We investigate cooperative investment for the deployment of a new infrastructure, and how it interacts with access obligations and demand uncertainty. Co-investment increases total coverage only if service differentiation and/or cost savings from joint investment, in particular due to high...

In a spatial competition setting there is usually a non-negative relationship between competition and quality. In this paper we offer a novel mechanism whereby competition leads to lower quality. This mechanism relies on two key assumptions, namely that the providers are motivated and...

We study a market model in which competing firms use costly marketing devices to influence the set of alternatives which consumers perceive as relevant. Consumers in our model are boundedly rational in the sense that they have an imperfect perception of what is relevant to their decision...

We study a vertically differentiated market where two firms simultaneously choose the quality and price of the good they sell and where consumers also care for the average quality of the goods supplied. Firms are composed of two factions whose objectives differ: one is maximizing profit while...

We study optimal experimentation by a monopolistic platform in a two-sided market framework. The platform provider faces uncertainty about the strength of the externality each side is exerting on the other. It maximizes the expected present value of its profit stream in a continuous-time...

Platforms use search diversion in order to trade off total consumer traffic for higher revenues derived by exposing consumers to products other than the ones that best fit their preferences. Our analysis yields three key and novel insights regarding search diversion incentives, which have direct...
