This paper aims to empirically establish the determinants of merchant participation in credit card payment schemes. It is found that a merchant's personal background, type of business and total value of sales are significant in determining a merchant's acceptance of cards in payment...

We designed a platform with a betting mechanism for eliciting costly, dispersed information of different quality. Our objective is to elicit both dispersed information and the precision of the information so as to efficiently weight dispersed information to produce reliable forecasts. After...

We provide a theoretical result on the effect of piracy on the sales of legal product using the same framework as Gil (2006). We obtain that when the illegal sector is perfectly competitive and the marginal cost of the legal firm and the quantity tax are small enough, piracy does not lead to...

In this paper, we survey the literature on optimal pricing of a monopolist operating on a network industry. We also describe explicitly the optimal path of prices for a monopolist facing an expanding demand due to the presence of network effects. The optimal path of prices appears as a function...

The paper proposes an analytical framework for comparing different business models for producing information goods and digital services. It is based on three dimensions that also refer to contrasted literature: the economics of matching, the economics of assembling and the economics of knowledge...

Peer-to-peer (P2P) services allow users to share networked resources, notably bandwidth and content, from the edges of the network. These services have been popularized because of file sharing particularly the sharing of unlicensed copyrighted files. However, content owners are increasingly...

In a comment to my paper "The Economics of IPR Protection Policies," Martínez-Sánchez (2007) shows that in my model under certain conditions the presence of piracy increases the quantity produced by the legal monopolist firm. In this note, I show how the algebra used in Martínez-Sánchez...

This paper provides a first pass at comparing two polar strategies for market intermediation: "merchant" mode buying from sellers and reselling to buyers - and "two-sided platform" mode enabling affiliated sellers to sell directly to affiliated buyers. The merchant mode is more profitable when...

This paper argues that a cable operator with sufficient market power in the downstream multi-channel video programming distribution (MVPD) market can deny access to unaffiliated programmers, resulting in an upstream programming rival's exit or impaired dynamic efficiency. Further, market...
