Overview of the Economy

Measuring the Formal Economy

Gross Domestic Product (GDP)

• Definition: Measures the total economic output of a country over a specified time period.

• Calculation: $GDP = C + I + G + (X - M)$ Where:

  • C = Consumption

  • I = Investment

  • G = Government Spending

  • X = Exports

  • M = Imports

• Key points:

  • GDP factors in only domestic production.

  • An increasing GDP indicates economic growth, business expansion, job creation, and higher consumer spending.

  • A declining GDP reflects a shrinking economy, potential contraction, or recession, indicating struggling businesses and reduced consumer spending.

Gross National Product (GNP)

• Definition: Includes the value of all goods and services produced by a country's citizens, regardless of their location.

• Key differences from GDP:

  • GNP accounts for domestic production and production by citizens living abroad.

  • Foreign production within the country does not factor into GNP.

• Example to illustrate:

  • If Toyota, a Japanese company, builds a factory in the US, it contributes to the US GDP but not to the GNP since the company is not US-based.

  • Conversely, Starbucks, an American company, contributes to both US GDP and GNP when operating domestically but only contributes to China's GDP when it operates there.

Gross National Income (GNI)

• Definition: Total income earned by all of a country's citizens, regardless of location, including wages, profits, and investments.

• Focus: Income rather than production.

• Distinction between GNI and GNP:

  • GNI focuses on income generated by citizens and companies.

  • GNP focuses on domestic production of citizens.

GNI per Capita

• Definition: Average income earned by individuals in the country, calculated as:
  $ext{GNI per capita} = rac{ ext{GNI}}{ ext{Population}}$

• Implications: Higher GNI per capita usually correlates with more economic opportunities and a higher standard of living.

• Limitations: Does not reflect income inequality, quality of life, or other social aspects.

Measuring Social Development

Gender Inequality Index (GII)

• Definition: Measures inequality between women and men in three areas:

  1. Reproductive health

     • Indicators: Maternal mortality ratio and adolescent fertility rate.

  2. Empowerment

     • Indicators: Government positions by gender and education attainment levels.

  3. Labor Market

     • Indicator: Women's participation in the workforce.

• Scale: GII ranges from 0 to 1, with higher values indicating more inequality.

• Interpretation:

  • GII of 0 indicates perfect equality (no country currently has a score of zero).

  • Generally, more economically developed countries have a lower GII.

Human Development Index (HDI)

• Definition: Composite index measuring a country's level of human development based on three factors:

  1. Life expectancy

  2. Expected years of schooling

  3. Gross national income per capita

• Scale: HDI ranges from 0 to 1; higher scores indicate higher human development.

• Uses:

  • Compare development levels between countries.

  • Track changes in development over time and identify areas for improvement.

  • Countries with the highest HDI include Switzerland, Norway, Iceland, Hong Kong, Australia.

Measuring Development Resources

Renewable Resources vs. Fossil Fuels

• Observation: More developed countries tend to rely more on fossil fuels to meet energy demands.

• Dependence on fossil fuels results from the use of technology (cars, planes).

• Increasing trend: Higher levels of renewable energy also being utilized, particularly in developed countries with access to capital.
