Explosive Collisions at RHIC?

Motivated by experimental results from RHIC, we suggest how a condensate for the Polyakov loop might produce explosive behavior at the QCD phase transition. This is due to a rapid rollover of the condensate field below the transition temperature

Institutional change in the international governance of agriculture: a revised account

The place of agriculture in the General Agreement on Tariffs and Trade (GATT) prior to 1986 is usually described in terms of either exclusion or exemption from general trading rules. This paper reevaluates the ‘exemption’ argument and its corollary that the Uruguay Round Agreement on Agriculture (AoA) represented a punctuated equilibrium in the governance of agriculture. Instead it traces the dynamics of institutional change through the history of the GATT/WTO, distinguishing between multilateral trading rounds and the framework of trade rules as separate but linked contexts for addressing agricultural trade matters; and further disaggregating the latter into broad principles and specific rules. It is argued that the broad principles lacked detail but, paradoxically, initially this facilitated an approach to dispute settlement based on conciliation. Subsequent trade tensions exposed an inability to make definitive legal decisions on the compatibility of specific national rules with broad GATT principles. The AoA is rooted in these institutional antecedents, but claims of the legalization of the trade regime are belied by a continued reliance on political flexibility and bargaining.

WTO Regulations and Bioenergy Sustainability Certification – Synergies and Possible Conflicts

Biofuels are increasingly being produced and consumed as a partial substitute to fossil-fuel based transport fuels in the fight against climate change. One policy introduced recently by some countries to help ensure biofuels perform better than fossil fuels environmentally is sustainability criteria. These, typically, require lower greenhouse gas emissions than fossil fuels, considering not only their use but also production. Concerns have been expressed from various quarters that such criteria could represent WTO-incompatible barriers to trade. The present paper addresses two specific issues. First, it argues that biofuels should be treated like any other traded product under WTO law, in particular the GATT agreement. Thus an importing country could not impose different trade measures dependent on whether the biofuel was produced according to its sustainability criteria. Second, the TBT Agreement provides guidance on how to draw up international standards that can help ensure WTO compatibility. This cannot guarantee such compatibility, but it can help reduce significantly the chances of WTO Members bringing actions against a fellow Member’s biofuels sustainability criteria. There is little direct case law to draw upon, but it is argued that, if the TBT guidance is followed, in the long term the absence of case law can be taken as an indication that sustainability criteria are WTO-compatible.biofuels, sustainability, WTO
