Street vending is pervasive across the globe, especially in developing countries. It provides an important source of earnings for the unemployed in urban areas, as well as a source of relatively inexpensive goods and services for city residents. However, typical street vendors face a common set of problems, which range from tenuous property rights and harassment from civic authorities to subsistence living and earning. Under this precarious setting, street enterprises have been expanding. The objective of this article is to employ a systematic method to research the studies in this field, extract their findings, and integrate them in order to propose a model that incorporates factors affecting the success of street enterprises. Based on this model, major research issues are outlined to advance the knowledge in the field. © 2013 Wiley Periodicals, Inc.
