After winning election in 1973, Detroit’s first black mayor, Coleman Young, consolidated his power, driving white residents, who had voted against him, out of the city by withdrawing services from their neighborhoods. Eventually, Detroit became “an overwhelmingly black city mired in poverty and social problems”—and shrinking fast.
Known as "The Curley Effect "....

Glaeser and Shleifer summarize their "Curley Effect" thesis as follows:
"It is generally thought in economics [that] [g]ood policies bring in resources and voters; bad ones keep them out. With the Curley effect, this result is reversed. When politicians seeking to stay in power use distortionary policies to force out their political opponents, [it] renders bad policies more, rather than less, attractive. The Curley effect, and more generally the economics of shaping the electorate, might thus shed light on a broad range of government policies that appear too bad to be true from alternative perspectives.
