impact of moonlighting job in economic and company, do u have example or journal?

Answer 1

Don't fully understand your question, however I will attempt to give you information.
By "moonlighting" I assume having a job that is an unofficial ie the income is undeclared. It may be a second job or done by someone on unemployment.

Some effects - Unemployment figures ore incorrect
Persons don't pay income tax / payroll tax is reduced
People employed in such ways may be illegal immigrants too.
