Evolution in Financial Markets Historically, a recurrent theme in economics is that the values to which people respond are not confined to those one would expect based on the narrowly defined canons of rationality. http://nobelprize.org/nobel_prizes/economics/laureates/2002/smith-lecture.pdf
Evolution in Financial Markets In his book Rationality in Economics, Vernon Smith suggests that ‘experimental economics and behavioral economics are complementary’: The experimentalists study market performance (market rationality), incentives in public good provision and small group interactions, and other environments with dispersed individual valuations, whereas cognitive psychologists the performance consistency (choice rationality) of individual decision making’. BUT the ‘connective interface between rationality at the individual level and the market level and how institutions modulate their interface is yet to be fully explored and understood’ (2008:155) http://nobelprize.org/nobel_prizes/economics/laureates/2002/smith-lecture.pdf
Evolution in Financial Markets Experimental economists have reported mixed results on rationality: people are often better (e.g. in two-person anonymous interactions), in agreement with (e.g. in flow supply and demand markets), or worse (e.g. in asset trading), in achieving gains for themselves and others than is predicted by rational analysis. Patterns in these contradictions and confirmations provide important clues to the implicit rules or norms that people may follow, and can motivate new theoretical hypotheses for examination in both the field and the laboratory. http://nobelprize.org/nobel_prizes/economics/laureates/2002/smith-lecture.pdf
Evolution in Financial Markets Constructivist rationality The first concept of a rational order derives from the standard socio-economic science model (SSSM) going back to the seventeenth century. The SSSM is an example of what Hayek has called constructivist rationality (or ‘constructivism’), which stems particularly from Descartes (also Bacon and Hobbes), who believed and argued that all worthwhile social institutions were and should be created by conscious deductive processes of human reason. In economics the SSSM leads to rational predictive models of decision that motivate research hypotheses that experimentalists have been testing in the laboratory since mid twentieth century. http://nobelprize.org/nobel_prizes/economics/laureates/2002/smith-lecture.pdf
Evolution in Financial Markets Ecological rationality These considerations lead to the second concept of a rational order, as an undesigned ecological system that emerges out of cultural and biological evolutionary processes: home grown principles of action, norms, traditions, and ‘morality’. Ecological rationality uses reason– rational reconstruction–to examine the behavior of individuals based on their experience and folk knowledge, who are ‘naïve’ in their ability to apply constructivist tools to the decisions they make; to understand the emergent order in human cultures; to discover the possible intelligence embodied in the rules, norms and institutions of our cultural and biological heritage that are created from human interactions but not by deliberate human design. People follow rules without being able to articulate them, but they can be discovered. http://nobelprize.org/nobel_prizes/economics/laureates/2002/smith-lecture.pdf
Evolution in Financial Markets Ecological vs. Constructivist rationality Rational theory: one represents an observed socioeconomic situation with an abstract interactive game tree. Contrarily, the ecological concept of rationality asks from whence came the structure captured by the tree? Why this social practice, from which we can abstract a particular game, and not another? Were there other practices and associated game trees that lacked survival properties and were successfully invaded by what we observe?
Evolution in Financial Markets Case Studies for Ecological Rationality: Deregulation in the late 1970’s in the USA and to a lesser extent in Western Europe, is a good example of paradigmatic change in thought and action in markets. Airlines, flag-carriers or semi-state monopolies, and monopolistic energy utilities, were deregulated after a status quo maintained since the 2nd World War.
Evolution in Financial Markets Case Studies for Ecological Rationality: In airline and energy generation/supply deregulation we clearly see the role of technology that facilitated/hindered the success of the innovative economic/financial systems. The inclusion of computers and information technology artefacts in a milieu of changing attitudes of stakeholders - politicians, economists, a materially better-off populace, faster news and commentary devices- is a good example of what Hardy and Mackenzie’s (2005) ‘assemblage’ or agencement that is the collective stakeholders and machines. Stakeholders in airlines and energy utilities did fail to update their beliefs correctly, sometimes machines in the agencement them, and stakeholders did act in a contrarian manner. Stakeholders, particularly the regulators, appeared risk averse in gainful situations and other stakeholders, like owners of enterprises and customers appeared risk seeking in turbulent times.

Hub-and-spoke was made possible with an agencement of entrepreneurs (Fred Smith), real-time/cheap computers and communications systems, innovations in supply-chains, and the adaptation of topology theory, economic theory (Hayek’s theory of money and fluctuations, for example), development in aeronautics and aerospace, and investment banking.

Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: California Electricity Deregulation An innovation that was designed to help key stakeholders in the energy business – generators, suppliers, customers- for a maximizing their utility under the watchful eye of a number of regulators. The development of efficient and low-cost control systems, will help in the efficient operation of the network where customers and shareholders will get best-value-for money and the state will maximise the tax revenue. Wholesale prices were deregulated, retail prices were capped, owners of existing transmission networks, often generators, had their rights/investments protected.
Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: California Electricity Deregulation Unfortunately, ‘the traditional volatility in the marginal cost of generated electricity was immediately translated into volatile intraday and intraseasonal wholesale prices’. More importantly, droughts, floods, catastrophic machine failure – ‘Events of small probability happen at about the expected frequency, and since there are many such events, the unexpected is not that unlikely’ (Smith 2008:50-51)

Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: California’s electricity market deregulation process from a subsidy viewpoint (Ritschel and Smestad 2003) ‘Deregulation and re-regulation of California’s electricity market not only failed in terms of anticipated cost reductions, improved customer service and higher competition, it also led to the introduction of various additional energy subsidies. Under deregulation in California, investor-owned utilities were not allowed to pass their energy procurement costs fully on to their customers, and therefore subsequently, and inevitably, ran into severe financial problems. Such retail price regulation is an energy subsidy that is both economically and environmentally unfavorable, because it veils true price signals to electricity consumers and, in this way, discourages energy conservation. ‘( 2003:1379) Alexander Ritschel, Greg P. Smestad (2003) Energy subsidies in California’s electricity market deregulation. Energy Policy Vol. 31, pp1379–1391
Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: California’s electricity market deregulation process from a subsidy viewpoint (Ritschel and Smestad 2003) ‘Other policies implemented in California that represent perverse energy subsidies are the purchase of power by the state of California, the suspension of retail competition, and the potential misuse of money from the recovery of stranded costs. Many interventions implemented by the state to smooth out the impacts of the energy crisis insulated electricity consumers from market realities, supported the existing structure of California’s electricity market, which is predominantly based on fossil fuels, and suppressed market incentives to improve energy conservation.’(2003:1379) Alexander Ritschel, Greg P.

Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: California’s electricity market deregulation process from a subsidy viewpoint (Ritschel and Smestad 2003:1383) As defined by the US Energy Information Administration, an energy subsidy is ‘‘any government action designed to influence energy market outcomes, whether through financial incentives, regulation, research and development (R&D) or public enterprise’’ (EIA, 1992). Subsidies with an overall adverse effect on the society are defined as ‘‘perverse’’ (Myers, 1998). Alexander Ritschel, Greg P.

Evolution in Financial Markets Case Studies for Ecological and Constructivist Rationality: The key in both the case studies – one of substantial success and the other of a temporary unmitigated disaster – can be perhaps understood in terms of self-organised, evolutionary behaviour that when sensitively dealt within a rational framework work (Federal Express) and when the rationalist framework is not sensitive then there is a failure (California Electricity Deregulation). Interconnected notions of tacit v. explicit knowledge, feedback-control systems play a major role here.
Paradigm Shifts in Computing: Corporate Learning Can organisations learn? Feedback and Control Cybernetics is a subject that deals with the self-maintenance and self-control of systems, both mechanical and organic, through a feed-back process. Cyberneticians also study the communication of information in such systems. Donald Schon (MIT) & Chris Argyris (Harvard) used the principles of cybernetics to provide a framework for thinking about learning organisations.
Paradigm Shifts in Computing: Corporate Learning Can organisations learn? Feedback and Control Control: In engineering it means to allow a machine to run within safe parameters and for the machine to operate efficiently. Feedback: An important component of any dynamic system. The ability to take into account both the inputs and outputs of a system.
e u y w S C Paradigm Shifts in Computing: Corporate Learning – Control Systems 'Feedback control' is thus a mechanism for guiding or regulating the operation of a system or subsystems by returning to the input of the (sub)system a fraction of the output. The machinery or apparatus etc., to be guided or regulated is denoted by S, the input by W and the output by y, and the feedback controller by C. The input to the controller is the so-called error signal e and the purpose of the controller is to guarantee a desired response of the output y.
