This concluding chapter summarizes the critical insights that changemakers ought to consider in their attempt to lead and manage cocreation processes and enhance their impact. The chapter also addresses three crucial challenges to the advent of a sustainable future: the need to rethink the assumptions of mainstream economics, the need to secure political stability in times of rapid societal change; and the demand for the deepening democracy. Finally, the chapter argues that local efforts to build a sustainable future will only succeed if key economic, political, and democratic challenges are effectively dealt with at the global and national levels.

The paper published below was prepared by Taylor Ostrander for Frank Knight’s course, Economic Theory, Economics 301, during the Fall 1933 quarter.

This paper surveys the treatment of expectations in estimated Dynamic Stochastic General Equilibrium (DSGE) macroeconomic models.

A recent notable development in the empirical macroeconomics literature has been the rapid growth of papers that build structural models, which include a number of frictions and shocks, and which are confronted with the data using sophisticated full-information econometric approaches, often using Bayesian methods.

A widespread assumption in these estimated models, as in most of the macroeconomic literature in general, is that economic agents' expectations are formed according to the Rational Expectations Hypothesis (REH). Various alternative ways to model the formation of expectations have, however, emerged: some are simple refinements that maintain the REH, but change the information structure along different dimensions, while others imply more significant departures from rational expectations.

I review here the modeling of the expectation formation process and discuss related econometric issues in current structural macroeconomic models. The discussion includes benchmark models assuming rational expectations, extensions based on allowing for sunspots, news, sticky information, as well as models that abandon the REH to use learning, heuristics, or subjective expectations.

Certain elements of Hayek’s work are prominent precursors to the modern field of complex adaptive systems, including his ideas on spontaneous order, his focus on market processes, his contrast between designing and gardening, and his own framing of complex systems. Conceptually, he was well ahead of his time, prescient in his formulation of novel ways to think about economies and societies. Technically, the fact that he did not mathematically formalize most of the notions he developed makes his insights hard to incorporate unambiguously into models. However, because so much of his work is divorced from the simplistic models proffered by early mathematical economics, it stands as fertile ground for complex systems researchers today. I suggest that Austrian economists can create a progressive research program by building models of these Hayekian ideas, and thereby gain traction within the economics profession. Instead of mathematical models the suite of techniques and tools known as agent-based computing seems particularly well-suited to addressing traditional Austrian topics like money, business cycles, coordination, market processes, and so on, while staying faithful to the methodological individualism and bottom-up perspective that underpin the entire school of thought.

Kalecki's theory of the business cycle is rightly renowned for various reasons: in particular, besides itself providing an original contribution, it set the framework for Kalecki's ideas on effective demand, for his anticipation of a number of Keynesian elements, and for the development of Kalecki's related themes such as income determination and distribution. Although the secondary literature (both technical and descriptive) on this subject is immense, a specific aspect seems to deserve further reflection.

This study proposes targeted modernization of the Department of Defense (DoD's) Joint Forces Ammunition Logistics information system by implementing the optimized innovative information technology open architecture design and integrating Radio Frequency Identification Device data technologies and real-time optimization and control mechanisms as the critical technology components of the solution. The innovative information technology, which pursues the focused logistics, will be deployed in 36 months at the estimated cost of $568 million in constant dollars. We estimate that the Systems, Applications, Products (SAP)-based enterprise integration solution that the Army currently pursues will cost another $1.5 billion through the year 2014; however, it is unlikely to deliver the intended technical capabilities.

In the 2010 volume of Research in Political Economy, Alan Freeman put forth the intriguing and original hypothesis that “capitalism's inner laws express themselves in … different ways during booms and during crises” (Freeman, 2010, p. 217). When the business cycle is in an upswing, Freeman argues, the tensions and contradictions that will eventually interrupt the process of capital accumulation are camouflaged by the commodity form, and so appear as natural laws of motion. With the onset of a crisis, however, these tensions erupt into overt class conflict and so become transparent. The open political struggle represents an opportunity for transformative progressive action. While Freeman's development of this hypothesis is in many respects illuminating, his analysis is marred by a gratuitous methodological argument that has little bearing on what he wants to say about crises. His remarks on method would be merely distracting if they were accurate. But they are in fact misleading and therefore stand in the way of productive discussion of the essay's many useful observations.
