The following article called my attention at first because it deals with a very interesting building policy which has a direct effect on the city and, consequently, on urban planning. Secondly, it is also interesting because it shows how building policies, created by governments, have also a direct effect on the price of rents and housing demand.
I believe it relates to the the Public Finance class because it exemplifies how the government is able to change behavior through policies and laws and this is, most of the times, a sign of inefficiency.
