This study provides a critical examination of how different theoretical perspectives in entrepreneurship research translate into individual behavior, and whether such behavior is evident in the creation and development of new ventures. Using an alternative templates research methodology, the behaviors underlying the theories of effectuation, causation, and bricolage are evaluated to see whether such behaviors are observable in case study data describing the early development of six new ventures. The analysis highlights behavioral similarities and differences between the various theoretical perspectives in entrepreneurship research, providing insight into how these perspectives contrast and complement one another, and how they could be integrated in future research.
