This study focuses on the importance of 'new urban entrepreneurship' -in particular, ethnic or migrant business firms -as a major driver of creative and urban dynamics and economic vitality in urban agglomerations. The paper offers a general account of both backgrounds and socio-economic implications of migrant entrepreneurship in large agglomerations and highlights the socio-economic heterogeneity in motivation and performance among different groups of migrant entrepreneurs. This demographic-cultural diversity prompts intriguing questions about differences in business performance among distinct groups of migrant entrepreneurs, even in the same ethnic group. In the paper, a recently developed and amended version of data envelopment analysis (DEA), viz. super-efficiency, is presented and applied to a group of Moroccan entrepreneurs in four large cities in the Netherlands. The main research aim is (i) to identify the best-performing firms (so-called 'entrepreneurial heroes') from a broad management and business perspective, while (ii) the background of our findings are more thoroughly analysed. The paper ends with some general concluding remarks on urban business strategies.Key wordS: economic vitality, urban development, entrepreneurship, migrant entrepreneurs, diversity, global diaspora economy, economic spillovers Urban and Regional Studies, Drottning Kristinas väg, 30 10044 Stockholm, Sweden; e-mail: karima.kourtit@abe.kth.se

Setting the scene: the homo mobilisWe live in an era of foreign migration, characterised by the emergence of the 'homo mobilis'. Millions of people leave their home country annually in order to find a better fortune somewhere else. This mega-trend will most likely not come to a standstill in the foreseeable future. Open cross-border communication, global access to information about other countries and cultures, rising international orientation and mobility, and advancing social and economic globalisation have paved the road towards a geographical shift in human capital unprecedented in the history of our world (for more information see also Nijkamp et al. 2012). Clearly, migration is not an exclusive feature of our century, but the extent and nature of migrant flows are clearly distinct from previous periods. Apart from the global background of contemporary migration
