If the MPC were about 0.75 on average, this would imply a government spending multiplier of about 4, according to the simple formula used in introductory courses. However, real world estimates of the spending multiplier in the US are often in the (wide) range of 0.5 to 2.25. What is a frequently cited reason why the measured spending multiplier is lower than what the simple formula would predict

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
