Da Marginal Revolution"In Britain you pay seven times your annual income for a home; in the U.S. you pay three and a half." The British get 330 square feet, per person, in their homes; in the U.S., we get 750 square feet. Not only does Toll say he believes the next generation of buyers will be paying twice as much of their annual incomes; in terms of space, he also seems to think they're going to get only half as much. "And that average, million-dollar insane home in the burbs? It's going to be $4 million."
In Italia, quante generazioni servono ormai per pagarsi una casa? AncorA: uno dei motivi fondamentali, almeno negli USA ed ini Uk, e' la legislazione sui piani regolatori.
Toll agrees with Glaeser et al. that the key force driving up prices is zoning and growth regulations. In New Jersey it now takes Toll Brothers up to two million dollars in legal fees and ten years in time to get the permits necessary to build.
Altro elemento interessante per il caso italiano e' invece l'effetto del federalismo fiscale:
Susan Wachter, a housing economist at the Wharton School at the University of Pennsylvania, has an interesting public choice insight about why zoning is worse in Europe.
European towns also have less incentive to encourage development, Wachter says, because they generally do not, unlike their American equivalents, depend on their local tax base to pay for education and services, which tend to be federalized.
This implies that towns in states that reduce their reliance on the property tax - often done, as in CA, in order to "equalize" school funding or other expenditure - will soon restrict development. Go to it graduate students.
