A study on coal mining in [[Appalachia]] suggests that "the presence of coal in the Appalachian region has played a significant part in its slow pace of economic development. Our best estimates indicate that an increase of 0.5 units in the ratio of coal revenues to personal income in a county is associated with a 0.7 percentage point decrease in income growth rates. No doubt, coal mining provides opportunities for relatively high-wage employment in the region, but its effect on prosperity appears to be negative in the longer run."<ref>{{Cite journal | doi=10.1111/jors.12310 | title=Coal Mining and the Resource Curse in the Eastern United States| journal=Journal of Regional Science| volume=57| issue=4| pages=568–590| year=2017| last1=Douglas| first1=Stratford| last2=Walker| first2=Anne| bibcode=2017JRegS..57..568D|url=http://be.wvu.edu/phd_economics/pdf/14-01.pdf|ssrn=2385560| s2cid=157987462| archive-url=https://web.archive.org/web/20160603173931/http://be.wvu.edu/phd_economics/pdf/14-01.pdf| archive-date=2016-06-03}}</ref>

Another example was the [[Spanish Empire]] which obtained enormous wealth from its resource-rich colonies in South America in the sixteenth century. The large cash inflows from silver reduced incentives for industrial development in Spain. Innovation and investment in education were therefore neglected, so that the prerequisites for successful future development were given up. Thus, Spain soon lost its economic strength in comparison to other Western countries.<ref>{{cite book|last=Baten|first= Jörg |title=A History of the Global Economy.

A study of US oil booms found positive effects on local employment and income during booms but found that after the boom, incomes "per capita" decreased, while "unemployment compensation payments increased relative to what they would have been if the boom had not occurred."<ref>{{Cite journal|title = The Economic Aftermath of Resource Booms: Evidence from Boomtowns in the American West|journal = The Economic Journal|volume = 126|issue = 593|date = 2014-10-01|issn = 1468-0297|pages = 1092–1128|doi = 10.1111/ecoj.12173|first1 = Grant D.|last1 = Jacobsen|first2 = Dominic P.|last2 = Parker|s2cid = 14300122}}</ref>
