Economics Study Guide on GDP, Labor Market, Loanable Funds, and Economic Growth

Nominal GDP

  • Definition: GDP that is not adjusted for inflation.

Real GDP

  • Definition: GDP that is adjusted for inflation.
  • Relation: There is a measurement that relates nominal GDP and real GDP which is based on an inflation measure.
  • Important Note: This concept is essential for understanding actual economic growth versus merely nominal growth.

Labor Force Participation

  • Children and Retirees:
    • Children: Not considered part of the labor force.
    • Retirees: Not included in labor force statistics or unemployment calculations.

Loanable Funds Market

  • Supply and Demand:
    • Demand in the Loanable Funds Market: Refers to the demand to borrow.
    • Supply in the Loanable Funds Market: Linked to the quantity of funds available for lending.

Factors Affecting Supply of Loanable Funds

  • Time Preference:
    • Definition: Refers to the degree of patience an individual has regarding to saving or spending money.
    • Low Time Preference: Indicates greater patience; tends to increase savings in the supply of loanable funds.
    • High Time Preference: Indicates less patience; tends to decrease savings because individuals prefer spending.

Demographic Considerations

Quantity Theory of Money

  • Statement: The theory posits that spending equals income.
  • Growth Version: Recognizes that economic output can change over time, reflecting how money influences economic dynamics over time.
  • Application: Basic algebra will be needed to address problems concerning unknown variables in the quantity theory.

Solving Problems

  • Basic Algebra Requirement: Students must be prepared to engage in simple algebra to find unknowns from given data.

Solow Model of Economic Growth

  • Components of the Model:
    • Economic growth can be analyzed through three distinct lines in graph representation:
    1. Growth Line: Represents overall economic growth.
    2. Straight Line of Depreciation: Symbolized by "d" indicating the rate of depreciation.
    3. Investment Curve: The bottom curved line shows investment levels.
  • Key Terms:
    • Delta (δ): Rate of depreciation.
    • Gamma (γ): Rate of investment.
    • Y: Output.
    • Condition for Steady State: Identified when investment equals depreciation (.
