Which of the following is typically a goal of supply-side policies?

The goal of increasing overall economic capacity is central to supply-side policies. Supply-side economics focuses on boosting economic growth by enhancing the productive capacity of the economy, which involves various strategies designed to improve the efficiency and productivity of businesses. This can be achieved through tax cuts, deregulation, and incentives for investment in capital and labor. By increasing the capacity of the economy, supply-side policies aim to lead to higher levels of output and economic growth, ultimately benefiting consumers and society as a whole.

Other options focus on different economic approaches. For instance, decreasing production costs through subsidies primarily involves government intervention in specific markets, which is not the main thrust of supply-side economics. Regulating the money supply to curb inflation is a strategy that falls under monetary policy rather than supply-side policy. Enhancing consumer protection laws is more aligned with regulatory and welfare policies, which aren't typically the focus of supply-side initiatives aimed at overall economic capacity and growth.
