This paper analyses lawyer's choices of law in international sales contracts. It identifies key reasons for opting in or out of the CISG across different jurisdictions. The paper then examines aspects of this choice from economic and psychological perspectives: from the ability to externalize...

In recent years, ad blocking has become a significant threat to advertising supported publishers. Adblockers typically negotiate with publishers, allowing some ads to go through in return for a payment, a practice called "whitelisting'' in the industry. This paper builds an analytic model to...

We study a duopoly where the two price setting firms have symmetric information. The firms produce substitute goods with a state dependent common value. The information that is available to both firms about the unknown state of nature is also available to the consumers, who also have access to...

In this article, the authors show that blockchain can help in reaching the goals of antitrust law in situations where the rule of law does not (fully) apply. They detail what needs to be done to this end, from both a technical and legal standpoint

Why do lawyers in some jurisdictions continue to ‘automatically’ exclude the 1980 UN Convention on Contracts for the International Sale of Goods (CISG) in their choices of law for international sales contracts? Why do lawyers in other jurisdictions approach the decision very differently? Why...

The Metaverse provides an unprecedented opportunity to observe competition in the making and derive insights into the determinants of competition.Created in December 2022, the Metaverse Competition Agency (“MCA”) studies how economic competition emerges, evolves, and ends. The MCA method is...

Although most production activities involve multiple outputs, econometric models of production or cost functions normally involve only one single homogeneous output. The aim of this paper is to test the hypothesis that a multiproduct specification is superior to a model with a single homogenous...

In non-competitive market characterized by heterogeneous firms and price uncertainty, we discuss the measurement of economies of scale and scope due to process indivisibilities arising from the task-specific production processes of multiproduct firm. Two competing DEA cost models — one based...

In designing a production model for firms that generate multiple outputs, we take as a starting point that such multi-output production refers to economies of scope, which in turn originate from joint input use and input externalities. We provide a nonparametric characterization of cost...
