Dear all,
I want to know how to avoid winner-take-all. The objective function of the TIMES model is cost optimization, which can impose market penetration or technology share constraints. However, for multiple technologies, if every process is set (such as the transportation sector), there may be some questions such as 1) Not every process can be constrained. And if we add too many constraints, it is the intervention to the model? In this case, imposing economic policies such as carbon tax may not work, because the cost caused by the imposed carbon tax is not high enough or due to the constraint. And if no constraint is set, the model may select the process according to their costs and resource endowment, and the use of suboptimal option only after the lowest cost is used up. How do you solve this problem in the modeling process? Whether the TIMES model can be linked with a discrete selection model similar to the GCAM model, and the market share can be calculated based on the cost.
Thank you!
Look forward to your reply!
