10. The Lucas Critique states that economic agents respond to changes in their economic environment, and economic models should be flexible enough to allow for such optimal responses.

Does Dena's behavior contradict the Lucas Critique? Explain. (Hint: consider the income and/ or substitution effects of the shock.)
