Final answer:
An increase in the supply of music downloads means a greater amount is available at the same price, typically due to technological improvements or cost reductions, shown as a rightward shift in the supply curve.
Step-by-step explanation:
An increase in the supply of music downloads implies that there will be a greater availability of music downloads at the same price. This phenomenon can often be attributed to factors such as an improvement in technology which reduces production costs, making it cheaper for firms to produce and supply more music downloads. This situation is represented graphically by a rightward shift in the supply curve which indicates that suppliers are willing and able to offer more downloads for sale at each price level, without an increase in price.
Further, let's consider other factors like product quality and consumer demand. An improvement in the quality of music downloads may increase consumer preference for them, leading to an increased demand. Likewise, an overall increase in consumers’ desire or need for music downloads will cause a rightward shift in the demand curve. In economic terms, when demand outstrips supply, prices typically rise. However, if suppliers anticipate higher demand or experience lower costs, they might increase supply to meet the demand without raising prices, aligning with market equilibrium.
