Understanding GDP: Measuring Economic Output

• GDP stands for Gross Domestic Product, which measures the total value of final goods and services produced within a country over a given period of time.
• GDP can be measured in real or nominal terms, with the former focusing on constant prices and the latter on market prices.
• The economy can be divided into three sectors: primary (agriculture), secondary (industry), and tertiary (services), with each sector having its subsectors.
• In Italy, the contributions of these sectors are 3%, 22%, and 75%, respectively.
• Goods and services that cross the production line and are meant to be consumed are called final goods and services, while those that do not cross the line are called intermediate goods and services.
• GDP only takes into account the value of final goods and services, not intermediate ones.
• GDP can be measured at current prices, constant prices, or in terms of PPP prices.
• There are three methods to calculate nominal GDP: total value added, total income, and total spending on final goods.
• Total value added is the sum of the value added by each sector to the inputs it receives.
• Total income is the sum of the income earned by all those who participate directly or indirectly in the production of goods and services.
• Total spending on final goods is the sum of all spending on goods and services meant to be consumed.
• When GDP rises, it means that the total value-added, total income, and total spending have all risen.
