Employing a cross-sectional dataset for 48 states, we find mixed empirical evidence for the impact of diversity on Gross State Product (GSP) per capita growth: racial diversity reduces GSP growth, while linguistic diversity raises GSP growth. Our findings suggest that because English is used frequently by non-native speakers barriers to communications based on race are more pronounced and enduring than those based on linguistic differences. The results provide a justification for establishing 'weak ties' across diverse racial groups as a means to enhance economic performance.Keywords: Economic growth; Linguistic diversity; Racial diversity200910.1016/j.socec.2009.05.0062016-02-24
