The president can quickly direct the agencies of the executive branch to respond to economic by signing executive orders.

Explanation:

An executive order is an official statement from the president about how federal agencies and departments should use their resources. Most importantly, it does not need congressional approval to take effect. So when the president believes that executive agencies need to be quickly targeted to respond to the economic, he can sign an executive order that provides that.

Executive orders can assure everything from earlier policy reversals, such as Trump's approval of building two pipelines that Obama had discarded, to trivial things, such as Obama's instructions that government institutions stop working at noon on Christmas Eve 2015.
