Energy model, boundary object and societal lens: 35 years of the MARKAL model in the UK

Abstract Technical energy models operate within social systems and those that perform particular social as well as technical functions are more likely to be used. We illustrate this with the example of the MARKAL energy system model in the UK, a model that is also widely used internationally. In the UK, MARKAL modelling has a long history helping underpin government energy and climate policy. We trace the use of the model from its initial development in the mid-1970s to the present day, highlighting attributes that contribute to its role as a successful ‘boundary object’ for different but interconnecting energy policy communities. We suggest that changing images of the energy policy problem have enabled MARKAL to shift from an initial role in identifying technologies to reduce oil dependency to playing a key role in target-oriented climate policy. Furthermore, we argue that the ability of MARKAL to perform different roles for different groups has served to embed and institutionalise the model in the energy policy community. Moreover, the capacity of the model to represent detailed technology options has accorded with a technological focus that has suited prevailing, shared conceptions of the energy-climate policy problem

Revitalizing the global trading system : what could the G20 do?

Since 2008, G20 leaders have repeatedly committed themselves not to resort to protectionism and to conclude WTO negotiations expeditiously. The jury is out on the extent to which they lived up to the first promise; they failed to deliver the second. Anemic global trade growth rates since 2010 implies that trade has not been a driver of much needed economic dynamism. This paper argues that the G20 should pursue a more ambitious trade agenda and that there is much that greater leadership by the G20 could do to reinvigorate the trading system. A first step would be to commit to concrete actions that can be implemented by individual governments on a concerted basis and that center on reducing trade costs and improving access to services for firms. The Chinese presidency should also seek to have the G20 commit to more effective monitoring and analysis of trade policy broadly defined (including subsidies and investment incentives) and the impact of the many preferential trade agreements involving China, the EU and the US, the world's largest trading powers
