The article introduces a new way to model forests in a computer model that looks at how different parts of the economy affect each other. This is important because forests play a big role in climate change, land use, and energy. The researchers created a dynamic forest sector that changes over time and included how people expect things to happen in all parts of the economy. The main finding is that it's really hard to model forests in this way because forests are managed in complex ways and the market for timber is tricky.
