https://economicsdetective.com/2016/07/costs-ethnic-diversity-garett-jones/ https://economicsdetective.com/2016/07/costs-ethnic-diversit... > Williams and O’Reilly (1996) review dozens of studies showing that ethnic diversity has a negative impact on group performance. In the two decades since, more research has reinforced that result. Alesina and La Ferrara (2005) find that increasing ethnic diversity from 0 (only one ethnic group) to 1 (each individual is a different ethnicity) would reduce a country’s annual growth by 2 percent. Multiple studies (La Porta et al., 1999; Alesina et al., 2003; Habyarimana et al., 2007) have shown that ethnic diversity negatively affects public good provision. Stazyk et al. (2012) find that ethnic diversity reduces job satisfaction among government workers. Parrotta et al. (2014a) find that ethnic diversity is significantly and negatively correlated with firm productivity. > This may seem strange to you. If you’re like me, you probably enjoy diversity. You probably don’t observe the problems of low morale and high marginal costs that researchers have found in ethnically diverse workplaces.
