So here we go.

PART I — The Laws of Supply and Demand

Supply and demand determine the price of a good or service; on the other hand, price has an effect on the supply of and the demand for goods. (Note: Goods are objects and services are actions or activities. I use the word “goods” here to mean both goods and services.)

Let’s deal with the second one first, that is the effect that price has on supply and demand.

When the price of a good rises, logically the demand for that good will naturally fall. So we say that Price Up; Demand Down. The converse is also true. That is when the price of a given good falls, demand for that good will increase. [Price Down; Demand Up]

On the other hand, when the price of a good rises, the supply of that good will rise as suppliers (producers) are urged by rising prices and consequently increased profits to increase the supply of a particular good. So we say that Price Up; Supply Up. As in the above example, the converse here is also true. That is when the price of a good falls, production of this good will fall as well. Reasoning here is similar to the above-mentioned example where producers supply more as prices rise; by the same logic, when prices drop so does supply. [Price Down; Supply Down.]

So, to this point we can conclude that price affects both demand and supply as follows:

Price Up; Demand Down
Price Down; Demand Up

Thus the relationship between Price and Demand is inverse. When one variable goes up, the other goes down and vice-versa. That is when the independent variable – price in this case – goes down, demand, the dependent variable goes up.

Price Up; Supply Up.
Price Down; Supply Down

The relationship between Price and Supply is direct. In other words, when the price goes up, supply also goes up and when price declines so does supply.

Now for the relationships which exist between supply and demand on the one hand and price on the other. In these cases, supply and demand are the independent variables while price is the dependent variable in the sense that the supply of and/or demand for a good determines the price of this good, or the price of a good depends on both the supply of and demand for that good.

When the demand for a good increases, the price of this good also goes up. [Demand Up; Price Up]. The converse is also correct so that we when the demand for a good falls, so will the price. [Demand Down; Price Down].

Thus we have a direct relationship between demand and price. When one rises, so does the other and, conversely, when the independent variable falls, so does the dependent variable.

When the supply of a good increases, the price of that good will naturally fall. [Hence Supply Up; Price Down.]. On the other hand, if the supply of a good should decline, the price of that good will rise. [Supply Down; Price Up]

Thus we have an inverse relationship between supply and price. When one rises, the other (the dependent variable, price here) will decrease and vice-versa. i.e. when the independent variable (S in this case) falls, the dependent variable will fall.

So in summary, we have the following relationships among Demand (D), Supply (S) and Price (P). First, employing Price as the dependent variable …

D Up; P Up
D Down; P Down

S Up; P Down
S Down; P Up

Now using Price as the independent variable …

P Up; D Down
P Down; D Up

P Up; Supply Up
P Down; Supply Down
