Using the Triple Bottom Line Framework, which encompasses economic, social, and environmental dimensions, analyze the changes in the Federal Reserve's monetary policy from $2020$ to $2023.$

Complex Issues: Research and discuss how the Federal Reserve has adjusted its monetary policy tools $($reserve requirements, open market operations, and the discount rate$)$ during this period. Explain the complexities and rationale behind these changes.

Stakeholders: Identify and analyze the impact of these monetary policy changes on various stakeholders, including individuals, businesses, financial institutions, and the broader community.

Articulate a Solution: Select one specific monetary policy change and use the Aggregate Demand$-$Aggregate Supply $($AD$-$AS$)$ model to analyze its effects on short$-$run and long$-$run economic equilibrium. Propose strategies to optimize the outcomes of this policy for sustainable economic growth.

Evaluate Impact: Evaluate the overall impact of the selected monetary policy change on the US economy, considering its effects on the loanable funds market, labor market, and foreign exchange market. Use data from sources such as the Bureau of Labor Statistics $($BLS$),$ the Federal Reserve $($Fed$),$ or the US Census to support your analysis.
