WEEK 2 – MEASURING MACROECONOMIC PERFORMANCE What is Gross Domestic Product (GDP)?

• It is a measurement to determine the economic health of a country. • Economists take measurements of the economy to find out how the economy is doing. • GDP is the value of the aggregate production of goods and services in a country during a given time period. • It is the total market value of all final goods and services produced in the country during the period.

WEEK 2 – MEASURING MACROECONOMIC PERFORMANCE Ways to measure the GDP • Expenditure approach • Income approach • Value-added approach

WEEK 2 – MEASURING MACROECONOMIC PERFORMANCE The Expenditure Approach • The expenditure approach measures GDP as the sum of consumption expenditure (C), investment (I), government expenditure (G) and net exports of goods and services (X - M). • GDP = C + I + G + ( X - M )

WEEK 2 – MEASURING MACROECONOMIC PERFORMANCE The Value-added Approach • Value-added is the value of a firm’s final goods minus the value of intermediate goods bought from other firms • Only expenditures on final products – what consumers, businesses, and government units buy for their own use belong in the calculation for GDP • Counting the sale of final goods and intermediate products would result in double and triple counting

WEEK 2 – MEASURING MACROECONOMIC PERFORMANCE The Value-added Approach • For example, the tires that come with a car (when you buy the car) are not counted as a final good • However, if you get a flat tire and buy the same tire (to replace your flat), it is counted as a final good
