Suppose that your household gets a machine that costlessly provides you with food. What would that do to your labor supply? For credit, in your answer, discuss what the income effect will be of the mew invention, and what that will do to your decision to work. Also, discuss what the substitution effect will be of the new invention, and what that will do to your decision to work. (Hint, don't get bogged down by considering anything but what this will do to your household. Also assume that you are the only household that has such an invention and that the economy as a whole won't be affected.)
