Introduction
Individual markets and the decision-making of individual enterprises and households that meet in those markets are studied in microeconomics. The study of the entire economy is known as macroeconomics. This chapter, as well as the rest of the book, is on macroeconomics.
Income must match expenditure in a country’s macroeconomy. This is true because in every transaction, the seller’s revenue must equal the buyer’s expenditure. The gross domestic product (GDP) is a measure of the economy’s total income or output. Because income equals spending, GDP may be calculated by adding the income (wages, rent, and profit) or the expenditure on goods and services produced in the economy. That is, GDP equals income plus expenditure.
The measurement of gross domestic product
The market value of all final products and services produced inside a country in a specific period of time is defined as GDP.
- Market value means that the output is valued based on the price paid for it. As a result, higher-priced items are more heavily weighted in GDP.
- Of all, indicates that GDP tries to capture all of the economy’s output that is legally sold in markets. GDP, for example, excludes the manufacture and sale of illegal substances, as well as household production such as cleaning one’s own home. GDP does, however, include the projected rental value of owner-occupied homes as production of housing services in an attempt to be complete.
- Final meaning that GDP only includes products and services sold to the final consumer. Thus, GDP counts the sale of a Ford Taurus at retail, but it ignores Ford’s purchases of intermediate items like glass, steel, and tyres that were used up during the car’s construction. Intermediate goods are goods produced by one company and processed by another company. Double counting of intermediate production is avoided by counting only final goods and services.
- Goods and services meaning that, while GDP certainly includes tangible produced products like automobiles and trucks, it also includes intangible items like the services of lawyers and doctors.
- We omit the sale of secondhand things that were produced (and counted) in a previous period when we say “produced.” This avoids duplicate counting once again.
- GDP represents the value of production within a country’s geographic limits, as defined by the phrase “within a country.”
- We measure GDP per year or quarter when we say “in a specific period of time.”
- GDP data is statistically seasonally adjusted to remove systematic fluctuations in the data induced by seasonal events like Christmas and crop harvesting.
- GNP (gross national product) is a different way of measuring income. GNP is a metric that measures the income or output of a country’s permanent residents or “nationals” (both people and companies), regardless of where they are situated.
- What is the difference between GDP and GNP? It is common practice to compare economic activity across countries using GDP. In Australia, the GDP and GNP figures are fairly similar.
The components of GDP
The value of spending on final products and services can be added up to calculate GDP. Consumption (C), investment (I), government purchases (G), and net exports (N) are the four components of expenditures according to economists (NX).
- With the exception of new housing, consumption refers to what households spend on goods and services.
- Spending on capital equipment, inventories, and structures, such as new houses, is referred to as investment. Stock and bond purchases are not included in investment.
- All levels of government spend money on products and services, which is known as government purchases (federal, state and local). Transfer payments, such as government payments of pensions or benefits (such as unemployment compensation), are not included in government purchases because the government receives no goods or service in return.
- The value of foreign purchases of domestic production (exports) less domestic purchases of foreign production equals net exports (imports). Imports must be deducted since consumption, investment, and government purchases encompass all goods, both foreign and domestic, and the foreign component must be removed to leave solely spending on home production.
We can write Y = C + I + G + NX to represent GDP. This equation is an identity since the variables are defined in such a way.
Real versus nominal GDP
The value of output measured in the prices that existed during the year in which the output was created is known as nominal GDP (current prices). The value of output assessed in the prices that prevailed in some arbitrary (but fixed) base year is referred to as real GDP (constant prices). We can’t tell if the amount of goods and services has increased or if the prices of goods and services have increased simply because nominal GDP has increased from one year to the next. When we see that real GDP has increased, we can be sure that the amount of goods and services has increased as well, because each year’s output is evaluated using the same base-year prices. As a result, real GDP is a stronger indicator of economic output.
(nominal GDP/real GDP) x 100 is the GDP deflator. It is a measure of the current year’s price level in comparison to the previous year’s price level.
Between 1970 and 2007, Australia’s real GDP expanded at a rate of roughly 3.5 percent per year on average. During these years, there were a few instances of real GDP fall. Recessions are defined as periods of real GDP contraction.
GDP and economic wellbeing
Real GDP is a good predictor of a society’s economic well-being since countries with a high real GDP per person have better educational systems, healthcare systems, individuals who are more literate, better housing, a better diet, and so on. A country with a higher GDP is also more likely to win Olympic medals. In other words, a higher real GDP per person usually translates to more consumption per person. GDP, on the other hand, isn’t a perfect measure of material well-being since it ignores leisure, environmental quality, and commodities and services generated at home but not sold in markets, such as child-rearing, housework, and volunteer labor. Furthermore, GDP has no bearing on income distribution. The subterranean or shadow economy – the component of the economy that does not report its economic activity – is likewise not captured by GDP. GDP, for example, does not account for illegal drug sales or revenue that is not declared in order to avoid paying taxes.
Is GDP revenue and expenditure equal?
Every year, economists evaluate the economy and calculate GDP to estimate our entire output. Gross domestic product (GDP) is a metric that measures an economy’s entire output. GDP is the total market value of all final goods and services produced inside a country’s domestic borders during a specific time period. It is equal to the total income of the country’s households as well as the total expenditures. As a result, the entire value of output can be measured or estimated from either the income or spending side.
Our economy’s overall production may be measured in two methods that are commonly accepted. The revenue strategy is one, while the expenditure approach is the other. The income approach measures the total income received by all households in a country, whereas the expenditure approach evaluates the total amount of money spent by individuals, businesses, governments, and even foreigners on products and services produced inside the country’s boundaries.
Both of these techniques of calculating GDP are inextricably linked to our economy’s circular flow paradigm, in which families exchange goods and services.
Why do economists use both the expenditure and income approaches to calculate GDP?
Why are both the expenditure and income approaches used to calculate GDP? A practical way to assess GDP is to use the expenditure approach, which adds up the amount spent on goods and services. The income technique is more accurate because it sums up the incomes.
Why is it that the income and spending approaches are equal?
The Circular Flow Model comes in handy for estimating GDP. Because every dollar spent by one actor in the economy is an income for another, total income in the economy is equal to total expenditure in this simple model of the economy. As a result, income equals spending. GDP can be computed by adding all of the purchases made by the economy’s agents (expenditure approach) or by adding all of the revenue received by the agents and adjusting for depreciation (income approach) (income approach).
When computing GDP, which strategy is more accurate: the income approach or the expenditure approach?
The expenditure approach to estimating GDP is… more accurate than the income approach. much more practical
What is the difference between income and expenditure?
The revenue generated by a non-trading organization in a financial year is referred to as income, while outgoing expenses are referred to as expenditure. These are the foundation of an Income & Expenditure account, and their net balance at the conclusion of the fiscal year determines whether there is a surplus or deficit. 3.
What is the economic link between income and expenditure?
A consumption schedule is a term used to describe the relationship between income and expenditure. It’s a term that’s used to characterize household economic trends. Consumers buy more items when they have more money or the expectation of more money. This means that money is spent on expenses even when there isn’t enough revenue to cover them. This is a basic economic principle used to characterize national and global expenditure trends. To collect data on customer patterns inside its own industry, a company should evaluate the relationship between consumption and savings.
What is it called when income equals expenditure?
Aggregate income is the sum of all incomes in a given economy, adjusted for inflation, taxes, and double counting. Consumption expenditure plus net profits equal aggregate income, which is a type of GDP. In economics, the word “aggregate income” refers to a broad idea. It could represent the profits from the economy’s overall output for the producers of that output. There are other methods for calculating aggregate income, but GDP is one of the most well-known and commonly utilized.
Why does GDP computed using the expenditure method have to be identical to GDP calculated using the income method?
Why is it necessary for GDP computed using the expenditure method to be equal to GDP calculated using the income method? The amount of money spent in the economy must equal the amount of money made in the economy. One market participant’s money is another’s income.
GDP is the total worth of all final goods and services produced within a country’s geographic limits over a given time period, usually a year. It only takes into account goods and services produced within the country and excludes things imported from other countries.
We examined the word GDP in detail in our previous post, What Is Gross Domestic Product (GDP).
What does this GDP figure mean? What is the formula for calculating GDP? What are the different ways for calculating GDP?
GDP Growth Rate
The GDP growth rate is a key indicator of a country’s economic performance. It is the increase in GDP as a percentage from year to year. It reveals whether the economy is developing faster or slower than the year before. To eliminate the influence of inflation, most countries utilize real GDP.
The economy contracts when it produces less than the previous year, and the growth rate is negative. This indicates the start of a downturn. The recession becomes a depression if it remains negative for a long time.
Significance of GDP
GDP is a broad measure of a country’s economic activity that is used to estimate an economy’s size and rate of expansion. Businesses can use GDP as a reference to their company strategy because it provides a direct indication of the economy’s health and growth. Other economic indicators are also monitored by investors since they give a foundation for making investment decisions.
The GDP report’s “business earnings” and “inventory” data are excellent resources for equities investors, as both categories demonstrate total growth over time. Pre-tax profits, operating cash flows, and breakdowns for all key sectors of the economy are also included in the corporate profits statistics.
Income Approach :
The income earned through the production of goods and services is the starting point for the GDP income approach calculation. We calculate the income earned by all the factors of production in an economy using the income approach method.
The inputs that go into making the final product or service are referred to as factors of production. Within a country’s domestic limits, the factors of production for a firm are Land, Labor, Capital, and Management.
- The difference between the total revenue earned by citizens and corporations outside their place of origin and the total income generated by foreign citizens and companies within that country is known as net foreign factor income.
When we add taxes and subtract subsidies, the calculation becomes the Gross Domestic Product at Market Cost.
Expenditure Approach:
The second technique, known as the expenditure strategy, is the polar opposite of the income approach, as it begins with money spent on goods and services rather than income. This metric measures the total amount spent on goods and services by all entities within a country’s domestic borders. Let’s have a look at how to compute GDP using the spending method.
- C: Consumer Expenditure, which refers to when people spend money on various goods and services. For example, food, gas, and a car.
- I: Investment Expenditure, which refers to when firms spend money to invest in their operations. Purchasing land, machinery, and other items, for example.
- G: Government Expenditure, which refers to how much money the government spends on various development projects.
- Exports minus Imports, or Net Exports (EX-IM). i.e., we calculate GDP by include exports to other nations and subtracting imports from other countries into our country.
The nominal GDP of a country is calculated using the methods described above. In the next post, we’ll look at the distinction between nominal and real GDP.
Typically, both of these procedures are used to compute GDP, and the computations are done in such a way that the figures from both approaches should be almost identical.
Output (Production) Approach :
The GDP Output Method is used to calculate the monetary or market value of all products and services produced within a country’s borders.
GDP at constant prices, or Real GDP, is calculated to avoid a misleading estimate of GDP due to price level variations. GDP is estimated using the Output Approach using the following formula:
Real GDP (GDP at constant prices) Taxes + Subsidies = GDP (as per output method).
The Trend of India’s GDP & GDP Growth Rate
Agriculture and associated services, Industry (Manufacturing) sector, and Service sector are the three major contributors to India’s GDP. In India, GDP is calculated using market prices, with 2011-12 as the base year.
