Macroeconomics and GDP

CPI, GDP, and Macroeconomic Policy

Macroeconomic Goals

  • Price Stability: Maintaining low inflation.
  • Sustained Growth of Real GDP: Aiming for sustainable economic expansion.
  • Rising Employment: Increasing job opportunities.
  • A More Equitable Income Distribution: Reducing income inequality.
  • Move Global Competitiveness/Export: Aiming to improve competiveness for exports.

Gross Domestic Product (GDP)

  • Definition: The market value of all final goods and services produced in an economy within a specific time period, usually one year.
  • Only final goods and services are included, which are products purchased as final products.
  • Example: Tires purchased by consumers are final goods. Tires purchased by car manufacturers are intermediate goods, not directly counted in GDP to avoid double-counting.
  • All goods counted in GDP must be produced during the specified year.
  • GDP is defined in value terms, typically in dollars in the United States.

Nominal vs. Real GDP

  • Nominal GDP: GDP calculated at current prices.
    • Useful for understanding economic data for a single year.
    • Not adjusted for inflation.
  • Real GDP: GDP calculated at constant prices.
    • Used for comparing economic data across different time periods.
    • Adjusted for inflation to reflect actual changes in output.

Meaning and Significance of GDP

  • GDP serves as an indicator of economic activity and is often used to measure standards of living (GDP per capita).
  • GDP per capita is calculated by dividing the GDP by the population.
  • High GDP per capita is generally correlated with high standards of living.
  • Increasing GDP and GDP per capita over time suggests growth in economic activity and improvements in living standards.

Flaws and Limitations of GDP

  1. Non-marketed Goods and Services: Excluded from GDP.
  2. Underground Economy: Economic activities not reported to the government are not included.
  3. Value of Leisure: GDP does not account for the value of leisure time.
  4. Improved Product Quality: GDP may not fully capture improvements in product quality.
    • Example: Computers
  5. Environmental Impacts: Negative environmental effects of production are not deducted from GDP.
  6. Non-economic Sources of Well-being: Factors like job stress are not considered.
  7. Distribution of National Income: GDP does not reflect how income is distributed within the population.

Nonmarket Activities

  • The exclusion of non-marketed goods and services understates the total value of productive activities in the economy.
  • Example: Painting your parents’ house.
  • This exclusion also distorts comparisons over time and across nations.
  • Historical Context: In the 1950s, when most women were full-time homemakers, their services were not included in GDP. As more women entered the formal labor market and paid for services they previously provided themselves, GDP calculations changed.
  • In many Third World countries, families often grow their own food, build their own homes, and gather their own water and fuel, which are typically not reflected in GDP.

Underground Activities

  • The underground economy includes economic activities not reported to the government.
    • Reasons: Illegal activities or tax evasion.
  • Examples: Gambling, prostitution, drug trade.
  • Since these activities are not recorded, they are not included in GDP statistics.

Composition and Distribution

  • Composition of GDP: The types of goods and services included in GDP.
  • Distribution of Income: How national income is distributed within the economy.
  • Quality of Life Issues: Other factors influencing quality of life.
    • Value of leisure (e.g., comparing the U.S. to Western Europe).
    • Improved product quality (e.g., computers).
    • Environmental impacts.
    • Non-economic sources of well-being (e.g., job stress).

Government Revenue

  • Taxes: Collected from individuals, property owners, businesses, and consumers.
  • Government Borrowing: Issuing government securities, such as bonds and treasury bills.
    • These securities are IOUs, promising to repay the borrowed money plus interest at a future date.
    • Sold to banks, corporations, and individuals, both domestically and internationally.

Federal Taxes

  • Personal Income Tax: Placed on most forms of individual income.
  • Capital Gains Tax: Tax on net income received when an asset is bought at a lower price and sold at a higher price.
  • Payroll Taxes: Based on earnings from work, primarily for social insurance programs like Social Security and Medicare.

State and Local Taxes

  • State Taxes
    • Sales and excise taxes
    • Personal income taxes
    • Corporate (net) income taxes
    • Licenses
    • Property taxes
  • Local Taxes
    • Property taxes, primarily levied by local governments

Types of Government Taxes

  • Progressive Tax: Takes a higher percentage of income from high-income earners than from low-income earners.
    • Example: Federal personal income tax.
  • Proportional Tax: Takes the same percentage of income from all income levels.
    • Example: State personal income tax.
  • Regressive Tax: Takes a higher percentage of income from low-income earners than from high-income earners.
    • Examples: Sales tax, property taxes, excise taxes, Social Security tax.

Government Borrowing and its Effects

  • Government Issues Securities (Bonds): Anyone can purchase these.
  • Government Spending Financed by Borrowing: Expands the economy more than government spending financed through increased taxes.
    • Reason: Borrowing does not reduce individual spending as taxes do.

Budget Deficit and Surplus

  • Budget Deficit: When federal government spending exceeds federal government tax revenue in a given year.
  • Budget Surplus: When federal government tax revenue exceeds federal government spending in a given year.

The National Debt

  • Definition: The total amount of money owed by the federal government.
    • It is an accumulation of all funds borrowed by the federal government that have not been repaid.
  • No Limits: The government can theoretically borrow indefinitely.
  • Roll Over: Borrowing new money to pay off old debts.

Size and Benchmarking of the National Debt

  • Size: Over 3030 trillion.
  • Inflation Adjustment: Necessary for comparing debt levels across different years.
  • Benchmark: Gross Domestic Product (GDP).
  • Debt-to-GDP Ratio: A useful metric for assessing the scale of the national debt.
    • 53%53\% in 1940.
    • 122%122\% in 1946 (World War II).

Impacts of the National Debt

  • Positive Consequences
    • Enables the government to expand the economy as needed.
    • Supports expenditures that can benefit society.
      • Present: Social Security and poverty reduction.
      • Future: Investments in health and education.
  • Negative Effects
    • Inequitable income redistribution (burden on future taxpayers).
    • Rising interest rates.
    • Reduces private investment.
    • Interest payments made to foreign entities, leading to real transfer of income out of the U.S.
    • Crowding-out effect (government borrowing can increase interest rates).
    • Burden on future generations.
    • Offset by public investment.

Subprime Mortgage Loans and the Great Recession

  • Background: Prior to the Great Recession (2007), subprime lenders provided higher-rate mortgages to borrowers who did not qualify for loans from mainstream lenders, typically due to low credit scores.
    • These borrowers were often financially stretched.
    • Loans were frequently underwritten with high debt-to-income ratios (50-55%), exceeding traditional ratios (30-33%).
    • In half of the cases, lenders used stated income rather than documented income, with stated income often exaggerated (90% of the time).
  • Effect on Minorities and the Poor: A disproportionate number of subprime loans were issued to minority families.
    • Over half of the home loans made in 2005 to African American families were subprime loans.
    • 40% of loans to Latin American families were subprime loans.
    • By contrast, about 20% of loans made to white families were subprime loans.

The Financial Crisis of 2007 and 2008

  • Mortgage Default Crisis: A key factor in the financial crisis.
  • Many Causes: Government programs encouraging home ownership, bad incentives provided by mortgage-backed bonds, and declining real estate values.

The Great Recession: Impact and Recovery

  • Impact: Loss of more than eight million jobs, loss of half the value of the Dow and the S&P 500, loss of trillions of dollars in retirement accounts and household wealth.
  • Recovery: Full-time employment did not regain its pre-crisis level until August 2015.
