Linear Demand Equations – Shifts in Demand (changes in the ‘a’ and the ‘b’ variables)

In our 3rd lesson on linear demand equations we’ll learn how a change in a non-price determinant of demand can cause the ‘a’ variable to change and a shift inwards or outwards of the demand curve along the quantity axis.

In our final lesson on linear demand equations we’ll look at how a change in a non-price determinant of demand can cause the demand curve to pivot along the quantity axis, changing the ‘b’ variable, resulting in either an increase or a decrease in the responsiveness of consumers to price changes.

Introduction to Linear Demand Equations

This is an update to the 2012 version of the lesson introducing how to determine an equation for demand using price and quantity data from a demand schedule or a demand curve. In parts 2 and 3 of this lesson we’ll examine how changes in price and the non-price determinants of demand will lead to movements along a demand curve or a change in the ‘a’ and ‘b’ variables and a shift in demand.
