Supply-side fiscal policy to combat recession:

Ordering more output does not directly relate to supply-side fiscal policy. This option suggests a directive approach rather than a structural economic policy change. While increasing output may be a goal during a recession, it is not a mechanism of supply-side fiscal policy, which focuses on long-term changes like tax adjustments to incentivize production.

Government spending is typically associated with demand-side fiscal policy rather than supply-side strategies. While increasing government spending can stimulate demand in a recession, supply-side policies focus on enhancing the productive capacity of the economy through incentives like tax cuts, rather than direct spending increases.

While regulations can impact economic activity, they are not a tool of supply-side fiscal policy aimed at combating recession. Instead, supply-side policies often advocate for reducing regulations to encourage business growth and investment, rather than introducing new regulatory measures that could hinder economic activity.
