Why and How Humans Trade, Predict, Aggregate, and Innovate

Trading, forecasting, aggregating, and innovating (the  Four ) are key social interactions in human life at both the individual and aggregate levels. They are part of the human fabric because they stem from mankind’s peculiarities—heterogeneity, inclination to forecast, sociality, and inventiveness. But humans have multifaceted behavior, too. They are capable of having contradictory impulses towards one another, integrating and disintegrating as well as cooperating and dominating, and behaving prosocially and anti-socially. Hence, humans need to organize themselves in order to maintain, improve, and extend their social interactions as well as a safe and ordered life. Crucial intersections emerge naturally—the efficiency of humans’ way of tackling the  Four  is a joint product of economic systems, institutions, and behaviors. 

All told, the main idea of this book is to include in a single tour a collection of insights on why and how humans implement the  Four . The narrative highlights several connections as well as how key these businesses are as the traveler is escorted through some  Four -related behavioral problems and institutional solutions that humans have been, respectively, facing and elaborating over time. Economics students may exploit this book by both inserting what they are learning from textbooks into a wider framework and enjoying some of the hints revealed by the grand social theorizing of giants such as A. Smith and J. Schumpeter. But the proposed tour may also attract outsiders to economics who are curious about disparate economic themes linked to the  Four  but who wish to gain an overview without engaging in longer readings.
