In light of behavioral findings regarding inconsistent individual decision-making, economists have begun to re-conceptualize the notion of welfare. One prominent account is the preference purification approach (PP), which attempts to reconstruct preferences from revealed choices based on a...

The weak rationality principle is not an empirical statement but a heuristic rule for how to proceed in social sciences. It is a necessary ingredient of any 'understanding' social science in the Weberian sense. In this paper, first this principle and its role in economic theorizing are...

The purpose of the paper is to explore, from an assessment viewpoint, the ideas below. Economics, as a social science, has always considered sets of individuals with assumed characteristics, namely the level of knowledge, although in an implicit way in most of the cases. In this sense, an...

The rational expectations hypothesis (REH) is the standard approach to expectations formation in macroeconomics. We discuss its compatibility with two strands of Karl Popper's philosophy: his theory of knowledge and learning, and his "rationality principle" (RP). First, we show that the REH is...

Rich countries have developed a historically unprecedented capability to manage conventional risks - fire, floods, earthquakes etc., but also car accidents, many workplace risks, and more. It is based on two institutions - insurance markets and public risk governance - supported by a powerful...

This paper considers an economic approach to autistic individuals, as a window for understanding autism, as a new and growing branch of neuroeconomics (how does behavior vary with neurology?), and as a foil for better understanding non-autistics and their cognitive biases. The relevant economic...

The cornerstone of mainstream economic theory is the premise of rationality. Humans are assumed to be rational economic agents who, subject to the available information and limited resources, are able to select, among a set of alternatives, the best means to maximize their ends and their...

An under-appreciated aspect of F.A. Hayek's mature views about rationality is the inter-relation of the “pure logic of choice” and rule-following behavior. Sometimes it is asserted that Hayek abandoned his earlier understanding of individual rationality and replaced it with a completely...

This book chapter demonstrates that there has been from Adam Smith to Vernon Smith a tradition of economic scholarship that is grounded in the decision calculus of individuals, or what F.A. Hayek referred to as the logic of choice, which requires neither the heroic assumptions of omniscience,...

This paper translates F.A. Hayek's informal capital theory into a dynamic equilibrium model. The focus is restricted to Hayek's largely unrecognized contribution in "Utility Analysis and Interest", published by The Economic Journal in 1936, being restated in "The Pure Theory of Capital", first...
