This paper examines how cultural holes that exist at the intersection of institutional fields influence the exploitation of entrepreneurial opportunities. Through an exploration of physician-founded ambulatory surgery centers in the United States, we examine how the presence of cultural holes presented doctors with alternative beliefs, values, and practices to overcome the cultural constraints around entrepreneurship within the medical profession. In doing so, this study extends cultural entrepreneurship research by bringing cultural holes to the forefront, empirically showing how they facilitate entrepreneurial action and proposing other contexts where cultural holes may affect entrepreneurial actions and outcomes.

Social movements can disrupt existing industries and inspire the emergence of new markets by drawing attention to problems with the status quo and promoting alternatives. We examine how the influence of social movements on entrepreneurial activity evolves as the markets they foster mature. Theoretically, we argue that the success of social movements in furthering market expansion leads to three related outcomes. First, the movement-encouraged development of market infrastructure reduces the need for continued social movement support. Second, social movements’ efforts on behalf of new markets increase the importance of resource availability for market entry. Third, market growth motivates countermovement that reduce the beneficial impact of initiator movements on entrepreneurial activity. We test these arguments by analyzing evolving social movement dynamics and entrepreneurial activity in the US wind power industry from 1992 to 2007. We discuss the implications of our findings for the study of social movements, stakeholder management, sustainability, and entrepreneurship.

Although there exists a rich literature on fisheries traditional management systems in North and South America, Caribbean, Asia and Pacific islands, much less information is available on inland African fisheries. Presents the first regional‐scale survey of traditional management systems operated within the Lake Chad Basin. The survey focused on the status and organization of the local (de facto) management systems and their interactions with the modern (de jure) regulations. The results show that fishing activities within the whole Basin are still largely under the control of the traditional local authorities. The few open‐access fishing grounds are areas that traditional authorities have never controlled or water‐bodies that they have had to “give up” in recent times due to the presence of armed groups. These areas are also areas where illegal taxation systems operated by non‐legitimated governement agents have developed, essentially as a consequence of the remoteness and political instability of the whole Basin.

Die Frage «Wie weit kann die öffentliche Hand den Fremdenverkehr fördern?» unterstellt bereits die vollzogene Tatsache der staatlichen Förderung des Fremdenverkehrs. Sie scheint diese hinzunehmen, ja sogar davon auszugehen, dass der Staat den Fremdenverkehr fördern soll, vielleicht sogar muss, wobei es dann, nur noch einen Schritt bis zur Untersuchung und zum Entscheid darüber bedeuten würde, wie weit er iiberhaupt zu gehen imstande ist, um das apodiktisch feststehende Gebot der staatlichen Unterstüzung maximal zu erfüllen.

We consider the relationship between external aid and development in Mozambique from 1980–2004, identifying the specific mechanisms through which aid has influenced the developmental trajectory of the country. We undertake both a growth accounting analysis and review the intended and unintended effects of aid at the micro-level. Sustained aid flows to Mozambique, in conflict and post-conflict periods, have made an unambiguous, positive contribution to rapid growth since 1992. However, proliferation of donors and aid-supported interventions has burdened local administration, indicating a need for deeper domestic government accountability. To sustain growth, Mozambique must maximize benefits from natural resources while promoting constructive international market integration.
