Study Notes

Macroeconomics: A Comprehensive Analysis

  • Macroeconomics studies national and global economies, focusing on aggregate variables and long-term growth.
  • It examines complex interdependencies among economic factors.
  • It aims to understand short-term fluctuations and inform policy interventions.

Advanced Concepts in Macroeconomics

Dynamic Stochastic General Equilibrium (DSGE) Models
