For the questions below, answer either true or false. if you answer true, explain why it is true. if you answer false, give a counter-example. in all three examples you may assume demand slopes downward and supply slopes upward (that is, neither curve is either perfectly vertical or horizontal), and that both curves are smooth (like they are in the rent control questions, not discrete like they were in homework 2).  in the simple model of supply and demand covered in this class, a binding price ceiling will always decrease total surplus

Caleb construction (cc) incurs supervisor salaries expense in the construction of homes. if cc manufactures 100 homes in a year, fixed supervisor salaries will be $400,000. with the current construction supervisors, cc's productive capacity is 150 homes in a year. however, if cc is contracts to build more than 150 homes per year, it will need to hire additional supervisors, which are hired as full-time rather than temporary employees. cc's productive capacity would then become 200 homes per year, and salaries expense would increase to $470,000. how would cc’s salaries expense be properly classified? fixed variable mixed stepped curvilinear
