According to Wikipedia, atom economy is the percentage of mass of the desired product(s) compared to the mass of ALL of the reactants.

percentage yield is (actual mass/ theoretical mass) right?
yes

Is atom economy:

number of atoms in desired product / number of atoms in reactants   OR...

molar mass of desired product / molar mass of reactants   ?

less desired and more along the lines of:

 amount reacted into the chemical that you want *100/ total amount of reactants.
