We have price on the vertical axis because that’s how Alfred Marshall (1890) drew his graphs in Principles of Economics. For better or worse, Principles was hugely influential. And so the present-day convention is Marshall’s convention.

Is price always on the y axis?

The normal convention is to put the independent variable on the X axis and the dependent variable on the Y axis. This convention calls for price to be plotted on the horizontal axis and quantity on the vertical axis.

What axis does the price go on?

The demand curve is a graphical representation of the relationship between the price of a good or service and the quantity demanded for a given period of time. In a typical representation, the price will appear on the left vertical axis, the quantity demanded on the horizontal axis.

What does the Y axis always show on a demand curve?

In graph dependent variable is always taken on x-axis and independent variable on y-axis. Thus price is taken on y axis and demand in x-axis to show downward sloping demand curve in economics.

Which axis is most commonly used to represent price?

Price is most commonly represented on the x-axis. Price is most commonly represented on the y-axis. Price is most commonly represented at the 0,0 intersection of the y and x-axis.

Does time go on the y-axis?

How do you graph speed? On a distance time graph, the distance will always be the dependent variable on the y- axis. Time is the independent variable and will always be placed on the x-axis. The lines on the graphs can tell you many different things.

Why is it hard to estimate a demand curve?

The curve DD is unlikely to be a good estimate of the demand curve. market is competitive. Specifically, the equilibrium value of price is at the level where the demand and supply curves intersect. The important point to note is that the demand and supply curves for this product may have been different each year.

Why is price always taken on Y axis and quantity on x axis?

Thus price is taken on y axis and demand in x-axis to show downward sloping demand curve in economics. In Mathematics, technically there is no difference in taking function on x axis or y axis, but conventionally we most of the times use y axis for the output of the function.

Is the demand curve always taken on Y axis?

In Mathematics, technically there is no difference in taking function on x axis or y axis, but conventionally we most of the times use y axis for the output of the function. Similarly in Economics, technically there is no difference whether you take price on y aix or on x axis. In both cases, the demand curve will be sloping downward only.

Where does price go in a demand curve?

“Readers trained in other disciplines often wonder why economists plot demand curves with price on the vertical axis. The normal convention is to put the independent variable on the X axis and the dependent variable on the Y axis. This convention calls for price to be plotted on the horizontal axis and quantity on the vertical axis.

Why do economists put price on the vertical axis?
