Is GDP a stock or a flow
There is a question that many people ask – Is GDP a stock or a flow?
Indeed, it can be confusing to state the real definition of the Gross Domestic Product unless you understand the meaning of a flow and concept.
It all boils down to the point when these two are calculated and how it is done.
To help you understand better, here is a detailed look at the tow.
What is a flow?
A flow simply refers to a metric that is measured over a period of time. The word flow in itself is an indication that the measurement is based on the way items flow in a particular setting.
In economics, it is the way products flow in the economy. This is usually calculated over a period of one year and is used for various purposes.
Since GDP is measured over a period, it definitely is a flow. You can easily determine this by looking at the way different countries from around the world calculate their GDP and how they use the results.
What is a stock?
Unlike a flow, a stock is calculated at a specific time of the process. You can calculate a flow after the end of the financial year, at half point or even quarterly.
It all depends on the kind of data that one wants to record. In economics, a stock metric is usually a government debt because it simply refers to the outstanding amount at the point.
Based on this, GDP cannot be said to be a stock because you cannot calculate it at one point but over the entire period that you are working on.
The uses of GDP
The most significant usage of the Gross Domestic Product in economics is as an important indicator for gauging the health of the economy of a country.
By calculating GDP, you can easily tell the cumulative dollar value of all the goods as well as services that the country has produced over a certain period of time.
Simply put, it is the size of an economy.
After knowing that the Gross Domestic Product of a country is a flow and not a stock, you also should know a number of things.
If a country wants to grow its economy, it is important to ensure that the GDP continues to grow.
It stagnates or starts to reduce, that country us likely to plunge into recession and that will affect every sector of the economy.
