An increase in production subsidies will shift the supply curve to the right.
Production subsidies are payments or other incentives that are provided to producers to increase their production of a particular good or service. By reducing the costs of production, subsidies make it more profitable for firms to produce and sell a product at any given price level. As a result, firms are able to supply more of the product to the market at each price level, which causes the supply curve to shift to the right.
An outward shift of the supply curve means that more of the product is supplied at every price level, ceteris paribus. This increase in supply can lead to lower prices and higher output levels in the market. The demand curve, on the other hand, is not affected by changes in production subsidies since it reflects consumers' willingness and ability to purchase a product at various price levels. Therefore, an increase in production subsidies only affects the supply curve, and not the demand curve.
