WITCH model

The final aim of the ICARUS project is to develop a framework that can guide policy makers when deciding on climate-related innovation, while accounting for the crucial fact that innovation is an uncertain process.
This decision-support tool will be developed by integrating the experts’ judgments and results from the empirical analysis of patent, deployment and RD&D data into a stochastic formulation of the WITCH model.
WITCH (World Induced Technical Change Hybrid model) is one of the main modelling tools developed within FEEM’s Sustainable Development research programme.

Understanding technology diffusion: a key to sound policy making

Understanding the mechanism of technology diffusion, for its important repercussions on development, is a tremendously important task. In particular, the transfer of new, more efficient and less polluting ways of producing energy is beneficial in many ways: it can reduce energy poverty, alleviate local pollution and lower the cost of transitioning towards a low-carbon society. […]

Alternative Paths toward a Low Carbon World

This paper analyzes the economic and investment implications of a series of climate mitigation scenarios, characterized by different levels of ambition in terms of long term stabilization goals and the transition to attain them. In particular, the implications of fairly ambitious scenarios are investigated for the first time by means of the model WITCH. Although […]

Using expert judgments to enhance innovation modeling in IAMs

In the context of climate change, decision-making is an inherently uncertain process. The prospect of future technologies is uncertain, both in terms of economic and technological performance and in terms of consumers’ and firms’ adoption choices. It is hard to predict what will be the direction of climate policy over the next 10-20 years as […]
