When we talk about agentization, we mean the explicit creation of agent-based models to reproduce the results from conventional models. Green Growth is an economic theory that proposes the reduction of greenhouse gas emissions while the economy grows and there is prosperity for all. The strategy for modeling the mechanics of Green Growth was to introduce a standard Ramsey growth model and adding it three building blocks: endogenous technical progress (learning by doing), green and brown capital, and labor market with search. In this talk, I'll present the process and some results of the agentization of the first building block of the Green Growth Mechanics: the technical progress building block.
