President Trump’s proposal giving $2,000/adult and $600/child, up from $600/person subject to income limits will cost $300 billion extra. The House bill giving $2,000/person subject to identical income limits will cost $465 billion more. In 21Q1, the benefits will be minimal, the economy is at its maximal growth given social distancing. The added money will boost spending somewhat, but probably not till 21H2 when it may not be much needed.
