In January 2011, CCPD along with New York City Public Advocate Bill de Blasio, jointly released a study based on evidence from researchers across the nation showing that Walmart's entry into new markets generally undercuts local economies and kills more retail jobs than it creates. Later in the year, a follow‐up study was conducted that examined the potential impact of a Walmart superstore in the Gateway Estates II development, in Brooklyn's East New York neighborhood. The study suggests that if a Walmart should locate in the area it would most likely have the same negative impact on the local economy that Walmart has had in other large cities.
