supply

The law of supply states that the quantity supplied of a good is directly related to its price, ceteris paribus (all else held constant).
Higher price leads to higher quantity supplied due to increased marginal benefit and positive incentives for producers.

The supply curve is upward sloping, illustrating a positive relationship: as price increases, quantity supplied increases.
Points plotted on a graph represent price vs. quantity supplied, connecting points forms the supply curve.

Incentives: Higher prices provide greater rewards, encouraging more production.
Increasing Marginal Opportunity Cost: Higher prices can compensate for rising opportunity costs of production.

Technology: Improved technology lowers production costs, increasing supply (positive relationship).
Price of Resources: Rising resource costs decrease supply (inverse relationship).
Taxes and Regulations: Increased taxes/regulations lower supply (inverse relationship).
Profitability of Alternative Goods: Higher profits for alternatives decrease supply of the current good (inverse relationship).
Number of Producers: More producers increase total supply (direct relationship).
Producer Expectations: Expectations about future prices can influence current supply; effects vary based on the expectation type.

Change in Quantity Supplied: Occurs when the price of the good changes; represented by movement along the supply curve.
Change in Supply: Occurs when a factor other than the price of the good changes; represented by a shift of the entire supply curve.
Example: Increased resource prices lead to a decrease in supply (left shift), while an increase in the good's price leads to an increase in quantity supplied (movement along the curve).
