Population ecology of entrepreneurship
What is the population ecology theory of entrepreneurship? Hannan and Freeman's (1977) population ecology theory hangs on the assumption that environments can only handle a fixed number of organizations of each type. After a certain point is reached, there are diminishing returns to density that eventually balance out through the mortality of organizations. The theory is about the tension between the need to be considered as legitimate in order to compete, but also the need to be competitive. As more organizations enter the market, they become increasingly legitimate, but this leads to greater competition making survival more challenging. Thus, the early market is dominated by the need for legitimacy , while the later market is dominated by competitive forces of selection. As environments change, often due to innovations introduced by organizations within them, mortality rates increase for organizations experiencing high levels of resistance to change.
