Study Notes

Macroeconomic Instruments

Macroeconomic instruments are used to assess the state of an economy and compare economic growth and development with other economies.

Gross Domestic Product (GDP)

GDP measures the performance of a country's economy during a specified period.
GDP is the total market value of final goods and services produced in an economy during a specific period of time (normally a year).

Defining GDP

Market Value: refers to the market price of the various new goods and services produced in the specified time period.
Final goods and services: used or consumed by individuals, households, and firms (excluding intermediate goods).
Economy: refers to the geographic area (country borders) within which all the goods and services are produced.
Specific time period: normally a year or quarter during which only new goods and services are produced.

Importance of GDP to Businesses

Forecasts for future aggregate demand are usually expressed in terms of projected growth in GDP.
Assessments of the current state of the economy are based on the current and recent past level of GDP.
Economic performance has political and policy implications.
International comparisons of aggregate market size are based on GDP data.

Methods for Calculating GDP

Production Method (value added): adds up the value added at each phase of production.
Expenditure Method (final goods and services): adds up the value of all transactions once they have reached their final destination.
Income Method (incomes of the factors of production): adds up the income earned by households for the factors of production.

Gross National Product (GNP)

GNP refers to the production resulting from the employment of the permanent residents of a country wherever they might be.
GNP is derived by subtracting the factor incomes of foreigners earned by foreigners in the country from the factor income of permanent residents earned abroad.

Net Domestic Product (NDP)

NDP = GDP - depreciation, making allowance for the depreciation of assets.

Nominal vs Real GDP

Nominal GDP: compares the current GDP value with that of previous years.
Real GDP: expresses the GDP at constant prices, reflecting the true picture of a country's well-being.

Limitations of GDP

Non-market production: difficult to measure or estimate the value of activities not traded in a market.
Unrecorded activity: many transactions or activities are never recorded, including illegal activities and those that escape the tax net.
Data revision: original estimates are frequently adjusted as new and better data become available.
Economic Welfare: GDP does not consider unwanted by-products or negative externalities, and does not account for productivity improvements and quality of goods and services over time.
