A discussion dealing with aggregate demand and aggregate supply, and the introduction to basic concepts in open-economy macroeconomics. The specific areas of discussion are the AS-AD model, AS and AD curves, shocks in AS and AD demand, and key concepts in open-economy macroeconomics.

Aggregate supply (AS) and aggregate demand (AD) models, and AS/AD curves are essential to understanding macroeconomic fluctuations (business cycles). Discuss the importance AS-AD models are in explaining the macroeconomic conditions of the economy and business cycles like recessions. What factors shift AS and AD curves? How do you explain macroeconomic fluctuations using AS-AD models and AS/AD curves?
