Knowledge Questions: Hayek,Keynes and Beyond

This paper discusses the knowledge problem in terms of both the use and generation of knowledge. This is analyzed in the context of Hayek's failure to respond to the Keynes Challenge—the claim that markets fail to produce relevant knowledge—by suggesting that in the aftermath of The General Theory he was not well-positioned to address that problem. Ironically, his post-World War II work in cognitive psychology, The Sensory Order, offers a theory of the generation of knowledge which can provide a useful analogy for understanding the generation of market-level knowledge.     

Hodgson on Hayek: a critique

In his book Economics and Evolution, Geoffrey Hodgson offersa detailed critique of F. A. Hayek's writings on cultural evolution.Certain aspects of Hodgson's treatment appear to be inaccurate.This paper criticises Hodgson's critique.     

Hayek, Keynes, and modern macroeconomics

The Great Recession seems to be creating a change in the trend of macroeconomic thinking. Prior to the financial crisis of 2008, dynamic stochastic general equilibrium (DSGE) models dominated the macroeconomics literature without any apparent challengers on the horizon. Since then, however, we have seen an increasing interest in macroeconomic models that address the state of confidence (??animal spirits??), complexity, cognition, and radical uncertainty. Most of the renewed interest in animal spirits, complexity, cognition, and radical uncertainty has come from a more or less ??Keynesian?? perspective. We discuss the potential to emphasize these elements from a more ??Hayekian?? perspective and argue that Austrian approaches to macroeconomics along these lines are more likely to resonate with mainstream economists than in years past.     

Hayek,Mach, and the re-ordering of mind

This paper argues that Friedrich A. v. Hayek's theory of mind and the relation between mental and physical events, most systematically presented in his 1952 book, The Sensory Order, is indebted to Ernst Mach's theory, and, in particular, to his Analysis of Sensations, above and beyond what Hayek himself along with multiple admirers of his work ever cared to admit. By highlighting a number of important similarities between Mach's and Hayek's theories of the psychical/phenomenal and physical world/order, the paper aims to show that key aspects of Hayek's theory of mind can be traced to Mach's theoretical foundations. The paper further argues that some of the criticisms Hayek levels against Mach concern nonessential points, arise from the uncritical acceptance of common misinterpretations of Mach's theory, or are plainly wrong.     

Hayek and Experimental Economics

This paper is an address given to the Austrian legislature in Vienna, Austria on March 3, 2004. The main focus is on the connection between insights from F.A. Hayeks research program and experimental economics.     

Mises and Hayek on calculation and knowledge

The author thanks Roger Koppl and Roger Garrison for helpful discussions.     

Hayek Contra Pangloss: A Rejoinder

Whitman (1998) claims that Friedrich Hayek's theory of cultural evolution was not Panglossian. Denis's (2002) refutation relies on an overbroad definition of the term Panglossian, a misunderstanding of the implications of group selection theory, and an incomplete understanding of the nested character of evolutionary processes in Hayek's approach.     

Hayek and liberal pedagogy

The author employs Hayek’s concepts of knowledge and spontaneous order to outline a learning-centered alternative to teacher- and student-centered pedagogies. In a Hayekian classroom, learning (intellectual order) emerges from a polycentric web of instruction, study, conversation, frustration, and discovery that continually elicits and tests the knowledge claims of students and teachers. Yet, unlike Hayek’s impersonal market process, the process of liberal learning is both personal and impersonal. To capture this hybridity, the author supplements Hayek’s insights with those of Parker Palmer, a liberal educator whose analysis of the classroom as a community of truth is attuned to the interpersonal dimensions of knowing and learning.     

Hayek on corporate social responsibility

Hayek published a piece in 1960 that criticized corporate social responsibility as a norm for economic organizations, although he regarded corporate actions to be subject to essentially the same moral rules as individual action. This article identifies and reorganizes Hayek’s criticisms of social justice, the rule of law and morality, his comparison of the open society and the closed society, and his treatment of charity and altruism. The aim is to clarify the Hayekian perspective on CSR. These considerations explain why the ‘social’ perspective on responsibility is considered dangerous in a free society, how to separate legal compliance and morality from concerns about social justice.     

Hayek contra Pangloss on Evolutionary Systems

Some analysts have criticized Friedrich Hayek's theory of cultural evolution for implying that the rules, customs, norms, and institutions that emerge from the evolutionary process are necessarily efficient or desirable in all cases. This charge is unfounded. The present article defends Hayek versus his critics in two ways: First, it restates Hayek's own objections to the idea that cultural evolution produces optimal outcomes. Second, it shows, through an analogy with biological evolution, that Hayek's theory need not imply any such conclusion. Contrary to a widely held misconception, biological evolution does not produce organisms that are perfectly adapted to their habitats; insofar as cultural evolution shares common features with biological evolution, cultural evolution may be expected to display similar types of suboptimality or mal-adaptation. Insights from the theory of biological evolution also help to illuminate some areas of controversy with regard to Hayek's theory of cultural evolution, including: Hayek's advocacy of gradual change; the question of what selective forces drive the process of cultural evolution; and the alleged conflict between group selectionism and methodological individualism.     

Corruption,competition and democracy

This paper presents a model of the interaction between corrupt government officials and industrial firms to show that corruption is antithetical to competition. It is hypothesized that a government agent that controls access to a formal market has a self-interest in demanding a bribe payment that serves to limit the number of firms. This corrupt official will also be subject to a detection technology that is a function of the amount of the bribe payment and the number of firms that pay it. Under quite normal assumptions about the shape of the graph of the detection function, multiple equilibria can arise where one equilibrium is characterized by high corruption and low competition, and another is characterized by low corruption and high competition. Some suggestive empirical evidence is presented that supports the main hypothesis that competition and corruption are negatively related.     

OPEC, rationality, and the macroeconomy

This paper builds a simple two-nation macro-model which includes a large manufacturing economy, such as the OECD and OPEC. Its distinguishing feature is that OPEC is a revenue-maximizing cartel who exploits the imperfectly elastic oil demand curve emerging from the rest of the world's use of imported oil as an intermediate good. Unlike the case of a small open economy facing OPEC, the large open economy is found to have a vertical aggregate supply curve. Consequently, anticipated macro-policies have no effect on real GNP. Moreover, micro-policies which induce the adoption of oil-saving technologies are also found to be neutral.
