What would happen if every unemployed person in the nation all at once stopped looking for work for one month?

Well if they stopped looking for work for a month they wouldn't be counted as unemployed since they are not looking for work according to the DoL.

It wouldn't do much because the people who are unemployed are unemployed for a reason. They could have quit their old job and decide to look for a better one or their a student joining the workforce ( Frictional unemployment). Sometime people lose their jobs because the market has became to technical or don't need their skills. (Structural Unemployment)

Of course unemployment is worse when the economy is down and business are not hiring (Cyclical Unemployment) but what would happen when there is no unemployed people and the economy booms. There is no people to fill those positions and the economy grows; pure inflation.

So right now the economy in the US is at Full employment (Full employment = unemployment 5%) and things are fine.
