SALVIATI: Greetings, Sagredo, and Simplicio, my good friends. Yesterday, we resolved to meet today and discuss as clearly and in as much detail as possible the character and the efficacy of those laws of macro economics, which up to the present, have been put forth by the books of Aoki and Yoshikawa (2006) and Aoyama et al. (2010a), the very same authors of this book.

SAGREDO: Indeed, I am truly glad and honored to meet you and Simplicio on this occasion of the completion of this book.

SIMPLICIO: Indeed, indeed, (with a touch of doubt on his face) what is “macro-econophysics”?

SALV.: You must be familiar with “econophysics”. It is evidence-based economics as a science. You may recall that it has the word “physics” in it as many physicists have devoted their research to this area, guided by the concepts and ideals of physics in their heart.

SAGR.: I see that most of the authors are physicists, except for Prof. Yoshikawa, who I heard is a macro-economist.

SALV.: They both have put forth the same ideals of revolutionizing the way real economy is studied in their respective books before. Now they have joined forces to introduce the term Macro-econophysics.

SAGR.: I have heard that it shares its ideals with “agent-based modelling”, which is yet another great approach.

SIMP.: That is good. But isn't this book a mere collection of the respective topics from each of the authors?

SALV.: Absolutely not. They have been working together for the last few years, combining the best of physics and economics and publishing papers. They have spent many days and nights discussing all things big and small included in this book.

SAGR.: And look… they have Professor Richard Feynman's very hopeful words on the front cover.

SALV.: This book is one of the latest efforts to construct a science of economics, which forms a part of the basis of this new development and will be improved and passed on to the next generation of academics.

SAGR.: And look at this photograph taken by the first author (who, by the way, is the first author because of the names being listed in alphabetical order) on December 1, 1979, at UC Irvine, California. He and his famous van!
