I would like to thank my friends, Antonella (Nelly) Puglia in EUROSTAT and Antonino Genovesi in Assessorato Turismo ed Ambiente – Dipartimento Territorio ed Ambiente – servizio 6, for their direct contribution in my activity of data collecting. Thanks to Dott. Antonino Ballone in CCIAA for the same reason. Many thanks to Prof. Carmine Bianchi for having introduced me to System Dynamics and to Prof Francesco Andria for his support and the great opportunity he has given to me to continue my research activity. I am grateful to Prof. Pål Davidsen for having taught me System Dynamics and for his constant support and encouragement. I am grateful to my friend and colleague Valerio Lacagnina because most of the ideas and insights implemented in this work are the result of the research activity we carry out together. Many thanks to my friend Matteo Pedercini for his support and help even from abroad. Finally, there are four women I owe very deep thanks to. My true mentor, Prof. Maria Caliri, who gave me the opportunity to start my academic career and allowed me to spend one year in Bergen where I studied System Dynamics. My extraordinary grandmother, Francesca, who has always supported me with her love and prayers. My great mother, Caterina, for her strength, her courage, her advice and unique and personal way to be a mother. My sweet girlfriend Giulia for the special meaning she has given to my life. Without this unique poker of Queens this thesis would not exist. To them this thesis is dedicated. to Maria, Francesca, Caterina, and Giulia.
