What is Positive Economics?

Let’s say that we are talking about the market and price equilibrium. At a point, the equilibrium is what it is. When there’s no opinion on it, that statement will fall under this type of economics. That means it talks only about the descriptive options and statements, and it would not talk anything about the judgments or opinions offered by people (or experts).

History

If you follow a chronological sequence, we need to go back to 1891. John Neville Keynes first talked about the differences between positive and normative economics. He mentioned that this economics depicts “what is” and normative economicsNormative EconomicsNormative economics refers to economists’ opinions about what they believe. It may be true for some, but false for others. Furthermore, the statements mentioned under normative economics cannot be verified or tested.read more portrays “what ought to be.”

Then, in 1947, Paul A. Samuelson published a book from Harvard University Press – Foundations of Economic Analysis. In this book, he labeled the statements under positive economics as “operationally meaningful theorems.”

Later, in a 1953 book named “Essays in Positive Economics,” Milton Friedman talked about their methodology.

Positive Economics Statement Examples

You would agree that economics is not an easy subject to handle without examples. In this section, we will take some examples of positive economics and explain why we call them positive economics statements.

Statement # 1

The law of demandLaw Of DemandThe Law of Demand is an economic concept that states that the prices of goods or services and the quantity demanded are inversely related when all other factors remain constant. In other words, when the price of a product rises, its demand falls, and when its price falls, its demand rises in the market.read more – “If other factors remain constant, if price rises, demand declines; and if price decreases, demand inclines.”

This is the law of demand. It is a positive economic statement because demand will rise or fall if prices fall or rise in inverse proportion; when other factors remain constant. However, it is not an opinion. It is not a value-based description of what could be. It is not even a judgment of an expert stating about the price and demand. Rather, it is a descriptive statement that can be tested or verified and can be true or false.

But if it can be true or false, why do we need these sorts of statements? The reason is we need facts before we opine. It is important to know “what is” before we reach the point of “what ought to be.”

Statement #2

Income isn’t equal in all countries.

This statement again doesn’t tell whether it’s true or false. It’s also not the opinion of an economist or an expert. Rather it simply is. In some countries, this statement may not be true. But since there is a huge gap between rich and poor and as the middle class is quickly evaporating, we can state this.

This is a positive economic statement because we would be able to verify it by looking at the statistics of various countries. If we see that most countries suffer from the extreme upper and lower limit in wealth, this statement will certainly become the truth. Otherwise, we will call it false.

Statement #3

When the Government levies more taxes on tobacco, people started smoking less.

Ask any addicted smoker, and you would see that this statement isn’t true at all, and that’s why it’s a positive economic statement. Usually, when the government levies huge taxes on tobacco, people stop/reduce smoking. So it’s, it’s not an opinion since it is a fact (or opposite of fact). As a result, we can verify by looking at the various statistics.

If an economist or expert offers their sagacious comment, this statement will turn into a statement under normative economics.
