“This book is intended as an exploratory sketch of a revolutionary scientific perspective and conceptual framework as it might be applied to sociocultural systems. This point of view and still developing framework, as interpreted here, stems from the General Systems Research movement and the now closely allied fields of Cybernetics and information or communication theory.”

“While economic theory in general may be defined as the theory of how an economic condition or an economic development is determined within an institutional framework, the welfare theory deals with how to judge whether one condition can be said to be better in some way than another and whether it is possible, by altering the institutional framework, to achieve a better condition than the present one.”

“Knowledge management often generates theories that are too general or abstract to be easily testable. In some cases, simulation modeling can help. [WE have developed] an agent-based simulation model derived from a conceptual framework, the Information Space or I-Space and use it to explore the differences between a neoclassical and a Schumpeterian information environment.”

“Haavelmo was the ﬁrst to recognize the capacity of economic models to guide policies. This paper describes some of the barriers that Haavelmo’s ideas have had (and still have) to overcome, and lays out a logical framework that has evolved from Haavelmo’s insight and matured into a coherent and comprehensive account of the relationships between theory, data and policy questions. The mathematical tools that emerge from this framework now enable investigators to answer complex policy and counterfactual questions using simple routines, some by mere inspection of the model’s structure.”
