Cambridge Econometrics and E3M have recently done modelling for the European Commission DG Energy exploring how policy conclusions differ if the same set of scenarios are estimated with two different models: E3ME and GEM-E3-FiT. This kind of exercise could be problematic. If the …
A recent paper written by the economist Steve Keen has been causing a storm on Twitter. It is called ‘The appallingly bad neoclassical economics of climate change’ (see also here). The paper takes aim at the small-scale ‘Integrated Assessment Models’ that have in the past…
Cambridge Econometrics recently worked with the Cambridge Institute for Sustainability Leadership to look at the effect of climate neutrality on jobs and skills in Europe. As part of this effort FTT:Steel, a recently developed novel sub-module of CE’s E3ME model, has been used …
Global GDP: we currently project the COVID-19 pandemic will reduce global GDP by 5% below a no-virus baseline in 2020 and 2021
Private indebtedness: the impacts on private indebtedness suggest that the subsequent recovery will be slow: while pre-crisis growth rates are restored, the lost level of GDP is not made up (a similar profile to what followed the Great Recession)
Government action: to mitigate those impacts further, governments will need to scale up the socialisation of private debt (through direct subsidy) and not merely ensure that liquidity is provided
In my studies I will be exploring how theories of complexity can be connected to post-Keynesian economics and, ultimately, Cambridge Econometrics’ E3ME model. Like any new student, my first task is a big pile of reading. Near the top of the pile is a return to Keynes’ General Theory.
The General Theory was written a long time before modern theories of complexity were developed. However, there are not really glaring inconsistencies or incompatibilities in the text.
It is true that Keynes does mention equilibrium a lot (something regarded as a lifeless planet by complexity scientists) but usually in the sense of something dynamic that the economy moves towards, rather than attains (p343).
In September 2019 our latest book, Energy, Environmental and Economic Sustainability in East Asia, was published. It presents the results of our recent research with the REEPS network of environmental and ecological economists in East Asia.
Our analysis highlights some of the key challenges and suggests some potential solutions.
It almost goes without saying that East Asia will play a critical role in future global sustainability. Even leaving aside the sheer size of China, the region accounts for a large and growing share of total emissions and resource use. However, the region is far from homogenous, with each of the four countries we focus on (China, Japan, Korea and Taiwan) facing its own unique environmental and political challenges.
E3ME continues to evolve with the hard work of our team of modellers here at Cambridge Econometrics and the input of our highly valued academic collaborators.
So, it is once again time for improvements.
E3ME version 7.0 is currently near completion and will become operational in July 2019. It will include:
The critics of macroeconomic modelling often refer to the models as ‘black boxes’, mystifying entities whereby data is input and a set of results come out at the other side – the inner workings of the model itself are opaque.
It’s important to us that our tools, their scope and limitations, are understood.
Here, our Head of Modelling Hector Pollitt follows up on his first blog entitled “What is macroeconomic modelling and why do we do it?” by outlining some of the most important features of Cambridge Econometrics’ E3ME as they compare to the more mainstream Computable General Equilibrium (CGE) models.

The world is vastly underestimating the benefits of acting on climate change. Recent research from the Global Commission on the Economy and Climate finds that bold climate action could deliver at least $26 trillion in economic benefits through 2030.
This groundbreaking research, produced by the Global Commission and more than 200 experts, highlights proof points of the global shift to a low-carbon economy, and identifies ways to accelerate action in five sectors: energy, cities, food and land use, water and industry. The blog series, The $26 Trillion Opportunity, explores these economic opportunities in greater detail.
The model is currently being developed to incorporate further feedbacks, including the important links between local air pollution and human health, which will impact on the economy but also be important in their own right.
The land use tool currently being developed will introduce further feedbacks.
Recent results have shown the difficulty in limiting material consumption without reducing rates of economic growth, which could eventually point to a need to limit economic development.
