is legal to a state where gambling is illegal This move a necessarily raises GDP b necessarily decreases GDP 33 34 35 36 37 c doesn’t change GDP because gambling is never included in GDP d doesn’t change GDP because in either case his income is included If a state made an illegal activity such as gambling or prostitution legal, then other things the same GDP a necessarily increases b necessarily decreases c doesn’t change because both legal and illegal production are included in GDP d doesn’t change because these activities are never included in GDP If a state legalized gambling and then reversed its decision and made gambling illegal, then other things the same GDP a necessarily increases b necessarily decreases c doesn’t change because both legal and illegal production are
