Long-time US Friend of the Urban Clinic Alan Mallach was back in May for an intensive visit. Alan lectured on his new book the Divided City: Poverty and Prosperity in Urban American: see here for his policy prescriptions and key data tracking trajectories in low-demand US cities. Alan also advised a team of students in the Urban Clinic Internship course, developing a business plan for low-cost housing in Bet Hanina, Jerusalem. Finally, Alan led a Master Class with housing policy researchers, looking at neighborhood decline in Israel. Alan argued that adding new housing is probably not the most effective intervention for stemming neighborhood decline, particularly in far-flung areas -- and challenged us to explore good practice interventions in education, housing stability, and employment.
