We can cautiously summarise these results as follows: The model’s tendency to decrease the number of states in the long run is quite robust against variation of configurations. But on the other hand one can see that a majority of configurations tends to produce no nation development process at all: The number of states does not decrease significantly. Therefore, we obtain clear evidence that not all configurations lead to nation building while others do. The subsequent research questions that now arises is whether we can characterise those configurations that lead to nation building.
