The focus of the research was on understanding how economic growth, environmental policies, and tax changes are interconnected using mathematical models. The author investigated how pollution and efforts to reduce it affect economic development in both open and closed economies over different time frames. The study looked at how consumer choices and the accumulation of resources impact these interactions. The results showed that environmental policies can have both short-term and long-term effects on economic growth and that considering these effects is crucial for making sound policy decisions.
