According to The Economist, "Rent controls are a textbook example of a well-intentioned policy that does not work. They deter the supply of good-quality rental housing. With rents capped, building new homes becomes less profitable. Even maintaining existing properties is discouraged because landlords see no return for their investment. Renters stay put in crumbling properties because controls often reset when tenants change." (The Economist. (2019). "Regulating Rent: Control Your Instincts.". Sect. Leaders.) If rent control does not work, then why is it so common in cities across the world? Who bears the cost of rent control programs? Who benefits? Are there better ways for policy makers to expand the supply of affordable housing available to low-income residents? Discuss
