Study Notes
Relationship Between Changes in Demand and Production
- Increased demand typically leads to higher production levels as businesses respond to consumer needs.
- Conversely, a decrease in demand can result in lower production, potentially causing layoffs or reduced working hours.
Components of Aggregate Demand (AD)
- The primary components of AD include Consumption, Investment, Government Spending, and Net Exports.
- Import spending is NOT included in the calculation of Aggregate Demand.
Formula for Net Exports or Trade Balance
- Net Exports (or Trade Balance) is calculated as:
- Net Exports = Exports - Imports
Characteristics of Trade Surplus
- During a Trade Surplus, exports exceed imports.
- A country experiences an inflow of currency and may see improved economic health as a result.
Definition of Inventory Investment
- Inventory Investment represents changes in the stock of unsold goods.
- It indicates how much businesses are investing in maintaining or increasing their inventory levels.
Aggregate Demand in a Closed Economy
- In a closed economy with no imports or exports, Aggregate Demand (AD) can be expressed as:
- AD = Consumption + Investment + Government Spending
Marginal Propensity to Consume (C1)
- The marginal propensity to consume (C1) signifies the fraction of additional income that households spend on consumption.
- A higher C1 indicates that consumers are more likely to spend rather than save.
Equation for Private Savings (S)
- Private savings (S) can be represented as:
- S = Income - Taxes - Consumption
Endogenous Variables in the Model
- Endogenous variables are determined within the model and change in response to other variables (e.g., consumption, investment).
- Their values are influenced by the relationships established in the economic model.
Role of Governments with Exogenous Variables
- Governments have control over exogenous variables, which are influenced by external factors and are not determined by the model.
- Policy decisions, such as fiscal or monetary policies, shape these variables to impact the economy.
