David and Jonathan own identical homes. David has owned his home for many years and paid $100,000 for it. Jonathan purchased his home after a recent property tax increase and paid $80,000. Should the local assessor change the assessed value of Jonathan’s home to maintain horizontal equity? (Assume there has been no inflation in housing prices since David purchased his home and that David and Jonathan value equally all public services provided in the local community.) In your answer, carefully define all key concepts.
