In the following section, we turn to numerical application and address the prerequisite of harmonizing national accounts, energy balance, and energy price data to produce consistent hybrid input-output matrices as a basis of scenario exploration.
We highlight how this data treatment step reveals the discrepancies M kim section001 leontief io model biases induced by sticking to the conventional modeling usage of uniform pricing of homogeneous goods. These varied experiments regard international climate policy burden sharing; the more general numerical consequences of shifting from a biased standard CGE model perspective to the hybrid IMACLIM approach; the macroeconomic consequences of a strong development of electric mobility in the European Union; and the resilience of public debts to energy shocks.
In a last section we offer some conclusions and thoughts on a continued research agenda.
The 2nd IPCC report highlights what is arguably the peak of the competition between the two modeling chapels Hourcade and Shukla,after which both communities start considering bridging the gap between them through the development of hybrid models.
We specifically discussed the need for such hybrid approaches in Hourcade et al. This need stems from recognizing that standard macroeconomic models, whatever their paradigm optimal control, computable general equilibrium, econometric estimation, or the recently developing dynamic stochastic general equilibrium approach simulate rather aggregate energy supplies and demands through mathematical functions that are 1 quite plain for most of them continuous and infinitely differentiablefor a sheer analytical convenience that comes at the cost of maladaptation to observed or expected flexibilities of energy systems; 2 devised as first order proxies valid only in the vicinity of some initial state of the economy; 3 applied in the framework of growth theories unfit to represent technical change biased toward a drastic reduction of the energy intensity of growth.
Standard macroeconomic models are thus structurally incapable of representing the major and complex technical evolutions of the energy systems, the now so-called energy transition, that the conjunction of conventional energy scarcity and the climate conundrum seems bound to induce in coming years.
Conversely, detailed energy system models offer the scope and detail necessary to capture and aggregate at need the complex expected evolutions of the manifold energy production techniques and end-uses; 1 but they lack the integrative macroeconomic framework necessary to evaluate the total economic costs attached to these evolutions—be it only a comprehensive description of investment markets—and thus cannot possibly account for the feedbacks between the macroeconomic constraints and the energy systems shifts.
This recognition led to develop the IMACLIM-S model as an alternative to the standard computable general equilibrium CGE model, focusing on providing macroeconomic consistency to the partial equilibrium results of bottom-up models.
Beyond the much explored hybrid modeling strategies that link some disaggregated energy supply module to a standard CGE model, IMACLIM-S indeed constrains not only energy supply but also the energy demands of all economic agents however aggregated based on the explicit representation of energy systems specific to bottom-up approaches.
It has done so following two quite distinct methodological avenues, which we successively present in Section Two Coupling Avenues below. In Section Hybrid Modeling Results we sum up various results of applied work based on either one of the two modeling methods, insisting upon the value-added of BU and TD coupling.
In Section Conclusion and Further Research Agenda we draw some conclusions and reflect upon a continued research agenda. Two Coupling Avenues CIRED's years of research on hybrid modeling build on a profound dissatisfaction with the extension, in the wake of the oil crisis, of Solow's neoclassical growth model Solow, to energy questions 2.
That extension simultaneously meant: Under such a modeling framework of energy-economy interactions, a change in energy prices at any point in time, whatever its intensity, only displaces the KLEM input mix along some pre-determined, exogenous isoquant.
This cannot be a proper framework, especially in the shorter temporal terms, to assess the dramatic shifts expected from highly ambitious climate policy action, or for that matter from potential geopolitical instabilities, under the inescapable constraint of mostly strongly inert energy supply and end-use equipment stocks 4.
This critique has two main implications. The first is that any relevant model of energy-economy interactions must work in an induced technical change framework, in the tradition of Kennedy — 5i. Induced technical change as a dynamic production frontier.
The second implication is that any macroeconomic model of energy-economy interactions is bound to turn to energy systems expertise if it is to describe with any relevance the evolution of the techniques that supply energy and convert it into service heat, light, motion, information and communicationparticularly in the short term.An extended input output table compiled for analyzing water demand and consumption at county level in China.
