Аннотация:The literature on ethnic entrepreneurship emphasizes the role of ethnicity in facilitating group differences in enterprise based on access to ethnic-based resources. This treatment tends to conflate family-based resources with those of ethnicity. Using a framework derived from intersectionality theory, this qualitative study investigates how two aspects of the household economy, namely household composition and family ideology, shape intra-group differences among fifty middle-class Mexican-origin entrepreneurs. Findings reveal that household class and gender dynamics shape access to three family-based resources that facilitate enterprise: family labour, entrepreneurial capital, and inheritance; differences in entrepreneurial activity between family members exceed in some cases those observed between ethnic groups. This study reveals that intersectional dimensions of identity and collectivity influence entrepreneurial outcomes within ethnic households. This study encourages researchers to consider how multiple and intersecting dimensions of identity combine for a more complete understanding of American enterprise.
