International investment treaties

International investment agreements protect foreign investors against host country policy measures. The agreements have been severely criticised both in the policy debate, and by academic economists, lawyers and political scientists. Particularly contentious is that they allow private investors to pursue disputes against host countries (Investor-State Dispute Settlement, ISDS). It is argued that the agreements' stipulated compensation requirements dissuade countries from pursuing legitimate policies. These agreements have largely been ignored in Economics research. But there is a nascent literature. The purpose of this project is to contribute to these developments.

Standard-essential patents and the principles for international allocation of jurisdiction in International Law

A sizeable literature analyzes the appropriate interpretation of FRAND commitments for standard- essential patents. With few exceptions, the literature disregards international dimensions, despite the fact that most standards are used in international markets. This  project uses a simple economic setting to assess pros and cons of the main jurisdictional bases in International Law: the Territoriality and Nationality Principles when national regulatory authorities have conflicting views regarding the appropriate interpretation of FRAND commitments. The paper identifies situations where the bases can implement efficient outcomes, and where they fail. The paper also shows how non-discrimination obligations might improve upon the outcomes.

Integration of electricity markets with national transmission systems operators 

In this project we develop a framework for analyzing the incentives of national transmission system oper- ators (TSOs) to supply cross-border interconnection capacity in an international electricity market. Our results show that equilibrium transmission capacity is downward distorted, even in situations where full capacity utilization is ine¢ cient. We derive a method for quantifying these distortions and propose a market design that uniquely implements e¢ cient dispatch of electricity. In this design, the distribution of trade adjustment payments causes TSOs to internalize the full e§ect of network congestion. The design would improve, for instance, on the current European market design.

The WTO Dispute Settlement data set

Henrik Horn and Petros C. Mavroidis (Columbia Law School) have assembled a data set on the use of the WTO Dispute Settlement system. The first version appeared in 2006 with support from the World Bank. The latest published version, updated i collaboration with the Global Governance Program at European University Institute, includes all 507 disputes that have been initiated since the launch of the WTO:s 1 January 1995 until May 2016. The data set includes around 50 000 data points. Each dispute is followed from its initiation through a Request for Consultation, via panel and Appellate Body proceedings to its end. It is currently being updated in a joint effort with economists and political scientists at the University of California San Diego.

Earlier projects:

Legal and Economic Principles of World Trade Law, American Law Institute

The purpose of this project was to create a forum for regular analysis of the WTO and its Dispute Dettlement Mechanism. The project was conducted under the auspices of the American Law Institute (ALI) from 2002, with Henrik Horn and Petros C. Mavroidis (Columbia Law School) as Co-Chief Reporters. The ALI is the leading independent US institution for legal analys, with approx. 4 000 elected members.

One purpose of the project was to let leading economists and lawyers jointly evaluate the emerging case law from the WTO Dispute Settlement Mechanism. The project still continues. To date, more than 100 reports have been written, covering alla disputes 2001-2019. The reports can be downloaded here

A second purpose was to evaluate central components of the GATT, the part of the WTO covering goods trade. The following reports was written as part of this effort: Economic and Legal Principles of World Trade Law: National Treatment (Gene M. Grossman, Henrik Horn and Petros C. Mavroidis)
