I have very little exposure to economic theory but quite a bit of exposure to complexity science. I took a look into the innovations you mentioned and it seems like nudge theory has its roots in cybernetics. Doesn't that inherently make it part of complexity economics? Cybernetics and systems theory are two sides of the same coin. The examples cited in the Wikipedia article do also appear to be clear examples of cybernetic governance, so it would appear less that nudge theory is influenced by cybernetics and more that it is just a form of cybernetic praxis.
