Cross price elasticity in TIMES?
#1

According to the the TIMES manual the cross price elasticity is set to zero. I have however read that it is possible to include cross price elasticity in the MARKAL-micro model.

 

Is it developed a similar TIMES-micro model variant? I think this would be useful, especially when modelling the transportation sector.

Thanks!

I donot know if markal-licro has been implemented in TIMES. Using cross price elasticities implies a non linear version of the model. Maybe Antti can abswer your question

To my knowledge, as yet nobody has implemented cross price elasticities into TIMES. As Denise mentioned, the MARKAL-MICRO variant requires the model to be solved as an NLP, which reduces the usability of the feature in large models. Anybody can, of course, implement such a feature into TIMES: the TIMES model generator is open source code and extensible.

Open source code evolves through community cooperation. The TIMES model generator is developed jointly by the members of the ETSAP community. If you would like to have a TIMES-MICRO variant, I strongly encourage you to implement it into TIMES, and then distribute it for the benefit of all ETSAP members.

Some good news: The Markal-Micro implementation has been investigated by some ETSAP partners now. And it seems that cross price elasticities based on CES functions (like those in the Markal NLP approach designed by Denise) can be supported in TIMES in the near future.
