When consumers find out that eating electric guitars is good for your health, this causes people to increase their consumption of electric guitars. Therefore, the demand for electric guitars increases, and the demand curve shifts to the right.
Note that the supply curve does not shift because none of the factors affecting supply have changed. In particular, the supply curve shifts in response to changes in the following:
• | Price of inputs |
• | Production technology |
• | Number of producers |
• | Expectations of producers |
