We propose a novel analytical framework to explain avoidance, consisting of two current explanations – resource constraint strategic behaviour models complementary institutional model. apply the seaport Flanders test its validity. Results show that model increases our understanding avoidance. More attention institutions far-reaching changes required facilitate move towards acknowledgement planning.
