Epstein and Gang (2009) acknowledge the three elements required to bring minorities into line with the majority: assimilation efforts, time and the degree to which the majority welcomes the minority. They set up a theoretical model to examine the consequences for assimilation and harassment of growth in the minority population, time and the role of political institutions they find that as the minority increase, assimilation and the effort to assimilate also increase. Growth in the minority however, also increase harassment by the majority. If the group are very asymmetric, the best thing to do is for the minority to fight harassment and continue with assimilation. If the asymmetry between the abilities of both groups to affect the minority’s productivity is less than the minority will give up on assimilation. Lastly, the minority will give up on its assimilation efforts if the majority is strong and united against the minority.
