The need for a better understanding of future energy scenarios, of their compatibility with the objective of stabilizing greenhouse gas concentrations, and of their links with climate policy, calls for the development of hybrid models. Hybrid because both the technological detail typical of Bottom Up (BU) models and the long run dynamics typical of Top Down (TD) models are crucially necessary. We present WITCH � World Induced Technical Change Hybrid model�� a neoclassical optimal growth model… 
The WITCH Model: Structure, Baseline, Solutions
WITCH – World Induced Technical Change Hybrid – is a regionally disaggregated hard-link hybrid global model with a neoclassical optimal growth structure (top-down) and a detailed energy input
The 2008 Witch Model: New Model Features and Baseline
WITCH is an energy-economy-climate model developed by the climate change group at FEEM. The model has been extensively used in the past 3 years for the economic analysis of climate change policies.
Stochastic scenarios for energy transition
This dissertation studies how uncertainty affects technology choice and investment decision in the context of a transition towards low-carbon economies. We use multi-region dynamic applied general
Integrated technological-economic modeling platform for energy and climate policy analysis
CGE (computable general equilibrium) and bottom-up models each have unique strengths and weakness in evaluating energy and climate policies. This paper describes the development of an integrated
Remind-D: A Hybrid Energy-Economy Model of Germany
This paper presents a detailed documentation of the hybrid energy-economy model REMIND-D. REMIND-D is a Ramsey-type growth model for Germany that integrates a detailed bottom-up energy system module,
Faraway, So Close: Coupled Climate and Economic Dynamics in an Agent-Based Integrated Assessment Model
In this work we develop an agent-based model that offers an alternative to standard, computable general equilibrium integrated assessment models (IAMs). The Dystopian Schumpeter meeting Keynes (DSK)
Optimal energy investment and R&D strategies to stabilize atmospheric greenhouse gas concentrations ☆
Stabilizing the atmospheric concentrations of greenhouse gases (GHGs) at levels expected to prevent dangerous climate changes has become an important, long-term global objective. It is therefore

In this work we develop an agent-based model that offers an alternative to standard, computable general equilibrium integrated assessment models (IAMs). The Dystopian Schumpeter meeting Keynes (DSK)
Measuring Impact of Uncertainty in a Stylized Macroeconomic Climate Model within a Dynamic Game Perspective
In this paper, we present a stylized dynamic interdependent multi-country energy transition model. The goal of this paper is to provide a starting point for examining the impact of uncertainty in
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


Entice: Endogenous Technological Change in the Dice Model of Global Warming
Despite growing empirical evidence of the link between environmental policy and innovation, most economic models of environmental policy treat technology as exogenous. For long-term problems such as
By modelling the decisions of households and firms, applied general equilibrium (AGE) models are able to capture the economic mechanisms that link, in each period of time, the available resource base
MERGE. A model for evaluating regional and global effects of GHG reduction policies
Abstract MERGE provides a framework for thinking about climate change management proposals. The model is designed to be sufficiently flexible to be used to explore alternative views on a wide range
Linking energy system and macroeconomic growth models
Though the computational complexity is greater the hard-link approach assures simultaneous energy and capital market equilibrium and leads to an energy market equilibrium.
Technological change and diffusion as a learning process
Energy and carbon intensities of aggregate economic activities, as measured by the gross domestic product, have generally been declining since the onset of industrialization two centuries ago
R & D-Based Models of Economic Growth
This paper argues that the "scale effects" prediction of many recent R & D-based models of growth is inconsistent with the time-series evidence from industrialized economies. A modified version of
A Robust Strategy for Sustainable Energy
The known energy resource base is more than sufficient to provide a growing world population with energy on the scale to which the industrial countries have grown accustomed and to which the
The Capital-Energy Substitutability Debate: A New Look
Over the last twenty years, many studies have been made of the elasticity of substitution between capital and labor. The reported estimates are highly variable, and reveal an apparent dichotomy
Projected Costs of Generating Electricity
Projected Costs of Generating Electricity – 2010 Edition presents the main results of the work carried out in 2009 for calculating the costs of generating baseload electricity from nuclear and fossil
Interfuel substitution in US electricity generation
Ongoing changes in the US electricity market include restructuring and increased competition. With this unfettering of the market, the fuel choice in generation is expected to become more flexible
