#### Slide 2: Learning Outcomes/Objectives
- Understand the components of the Keynesian model, including government spending and taxes.
- Analyze the impact of government expenditure and taxes on the equilibrium level of income.
- Explore the effects of introducing the foreign sector into the Keynesian model.
- Discuss the factors influencing the size of the multiplier in the economy.
- Evaluate the aggregate demand and supply model and its implications for fiscal policy.

#### Slide 3: Government Spending (G) in the Keynesian Model
- Definition of Government Spending
- Role of Government Spending in Economic Activity
- Stimulates demand and influences overall economic output
- Multiplier effect of government spending
- Example: Government investment in infrastructure leading to job creation

#### Slide 4: Taxes (T) in the Keynesian Model
- Definition of Government Taxes
- Effect of Taxes on Disposable Income and Consumption
- Income tax tiers affecting consumer behavior
- Relationship between taxes, consumption, and economic growth
- Example: Tax cuts as a fiscal stimulus to boost spending

#### Slide 5: Combined Effects of G and T
- Interaction of Government Spending and Taxes
- Impact on Equilibrium Level of Income
- How adjustments in G and T affect aggregate demand
- Summary of Findings: Government budget balance and its implications

#### Slide 6: Summary/Conclusion
- The Keynesian model highlights the significance of government intervention in managing economic fluctuations.
- Both government spending and tax policy are essential tools for influencing income levels and economic stability.
- Introduction of the foreign sector adds complexity to the Keynesian analysis, emphasizing the global interconnectedness of economies.
- Understanding these dynamics is crucial for policymakers to foster sustainable economic growth.
