Title: Sensitivity and Stability: An Investigation of Stock-Flow Consistent Climate-Economic Models
Abstract:
We aim to investigate the stability of various stock-flow consistent economic models, and the potential causes for economic collapse therein. Through parameter sensitivity analysis, we study models that feature a public sector, an active central bank, and a household sector with independent consumption. Our final, most comprehensive economic system combines all of the intricacies of each model, prominently featuring a demand-driven economy that is stabilized by an expansionary monetary policy. In addition, we incorporate a climate module for each economic system, and analyze public sector intervention through carbon taxes and abatement subsidies. We find that the most common feature of economic instability is a lack of demand, driven by decreases in capital investment from firms, as well as a decline in household consumption. In order to maintain a stable growth path and prevent a permanent economic contraction, we propose the implementations of an expansionary monetary policy, increased public sector subsidies of abatement costs, and stricter carbon taxes.
