Step 1: Define supply curve shift.
A rightward shift in the supply curve indicates an increase in supply, meaning firms are willing to supply more goods at each price level.
Step 2: List the factors.
The three main factors that lead to a rightward shift of the supply curve include:
1. Decrease in Input Prices: When the cost of inputs (such as raw materials, labor, etc.) decreases, firms are able to produce more at the same price, increasing supply.
2. Technological Advancements: Improvements in technology lead to more efficient production, allowing firms to produce more output at lower costs, thus increasing supply.
3. Government Subsidies: If the government provides subsidies or financial support to firms, their production costs decrease, leading to an increase in supply.
