Imagine you are a congressman trying to decide which of the two options to vote for. An economist asked to testify before Congress is explaining that based on a recent study, to increase economic growth from 2% to 4%, major increases in government spending, or major tax cuts need to be passed by Congress soon. The economist explains two alternative options to boost economic growth at the desired level: Option 1: Increase government spending on infrastructure by $20 billion. Option 2: Lower business/corporate taxes by the same amount, $20 billion.
