How does an increase in taxation affect producer surplus and marginal benefit in a competitive market?

When the government increases taxes on products in a competitive market, it raises the cost for producers. This means that producers will receive less money for each item they sell, which can reduce their profit, or producer surplus. For example, if a tax is added to a product that costs $10 to produce and is sold for $15, the producer might now only keep $13 after tax, lowering their surplus. Additionally, the higher price due to the tax can lead to a decrease in the quantity demanded by consumers, which means that the marginal benefit for producers may also drop since fewer products are sold. Overall, increased taxes can lead to a loss in economic efficiency known as deadweight loss, as both producers and consumers are affected negatively.
