(b) (6 points) If the good is allocated to the consumers who value it the most, does consumer surplus rise, fall or stay the same relative to the unregulated market (i.e., the competitive equilibrium without the price cap)? 

(c) (6 points) If the government instead uses a lottery to allocate the good, calculate the change consumer surplus relative to the unregulated market (i.e., the competitive equilibrium without the price cap)?
