In light of the interest in axiomatic models of decision making in recent years, one is led to ask, in what ways do axiomatic derivations advance positive economics? If economists are interested in predicting how people behave, without a pretense to change individual decision making, how can...

A general framework is described specifying how boundedly rational decision makers generate their choices. Starting from a "Master Module"; which keeps an inventory of previously successful and unsuccessful routines several submodules can be called forth which either allow one to adjust behavior...

This paper puts forward a new optical visualization of Supply and Demand curves from a Multi-Dimensional (MD) view. The idea behind showing Supply and Demand curves from the MD view is to propose the application of MD graphs among academics, economists and policy makers in the study of micro-...

This paper studies a balance whose unobservable fulcrum is not necessarily located at the middle of its two pans. It presents three different models, showing how this lack of symmetry modifies the observation, the formalism and the interpretation of such a biased measuring device. It argues that...

This paper explores the impact of excessive borrowing on economic stability, arguing that while debt can provide short-term benefits, it can lead to long-term financial distress and even economic collapse. The paper examines the benefits of debt, such as providing access to capital and managing...

In Tversky's (1969) model of a lexicographic semiorder, preference is generated by the sequential application of numerical criteria, by declaring an alternative x better than an alternative y if the first criterion that distinguishes between x and y ranks x higher than y by an amount exceeding a...

These notes review two simple heterogeneous agent models in economics and finance. The first is a cobweb model with rational versus naive agents introduced in Brock and Hommes (1997). The second is an asset pricing model with fundamentalists versus technical traders introduced in Brock and...

If we reassess the rationality question under the assumption that the uncertainty of the natural world is largely unquantifiable, where do we end up? In this article the author argues that we arrive at a statistical, normative, and cognitive theory of ecological rationality. The main casualty of...
