His work focuses on topics such as behavioural economics, theory of organisation and organisational learning, and theory of decisions, under the umbrella of the scientific approach developed by Herbert A. Simon (Nobel Prize 1980) from the 1950s onwards, which today is summarized as the "bounded rationality" approach [REF].
A parallel line is represented by the collaboration with Reinhard Selten (Nobel Prize 1994), again on the themes of bounded rationality, and by studies on Behavioural economics carried out in the last decade.
