4. How much? Here, you will need to draw a simple demand and supply model, shift the demand curve rightward a little, and then draw a second curve, shifting it rightward a lot
3. A positive or negative change? The ad campaign is successful, so it will shift the demand curve rightward.
2. Is the issue price or something else? It’s something else, so it will shift the demand curve—what causes the shift is a change in tastes or preferences, which is one of the factors that shift demand.
1. Is the ad campaign a demand or supply issue? Clearly, it’s a demand issue, so it will affect the demand curve.
3. Is the change an increase or a decrease?
2. Is price the issue, or is it something else? (If it’s price, it’s a movement along the curve; if it’s something else, it’s a shift of the curve. Numerous factors can shift demand and supply—work at finding which factor is affecting the change.)
