Hello, Professor Wolff. I'd like to know what you think about universal rent guarantee, a housing policy that was almost implemented in France. The idea is to compensate the landlords when their rent isn't paid, to avoid expulsion of poor people from housing. It is funded with a contribution of 2% of the rent from both the landlord and the tenant, and comes with strict rent control. Do you think this idea would help fighting homelessness and ending the housing crisis ?
