This paper aims to examine the performance conditions of ethnic (migrant) entrepreneurs in a modern economy. After a broad overview of key issues, all analytical tool from marketing theory is proposed, based oil the five Ps (Product, Price, Place, Personnel and Promotion). Next, an empirical application is presented, in which results from an in-depth interview study on Moroccan entrepreneurs in Amsterdam are discussed. Given the linguistic and qualitative information in our data base, two recently developed pattern recognition methods for categorized information, namely Apiori and rough set methods, are deployed in order to derive meaningful association and classification rules that are helpful to identify conditional success or performance rules. © 2004 Taylor and Francis Ltd.
