We propose an extension of Tversky's lexicographic semiorder to a model of boundedly rational choice. We explore the connection with sequential rationalisability of choice, and we provide axiomatic characterisations of both models in terms of observable choice data. -- Lexicographic semiorders ;...

We study a psychologically based foundation for choice errors. The decision maker applies a preference ranking after forming a 'consideration set' prior to choosing an alternative. Membership of the consideration set is determined both by the alternative specific salience and by the rationality...

This paper introduces four different focuses for microeconomics and macroeconomics that are based on the uses of multidimensional graphical modeling and multidimensional mathematical modeling. The main objective of this paper is to present some classic economic theoretical approaches such as the...

I study the effect of fatigue and innate ability on performance in a model with incomplete contracts, lumpy tasks requiring multiple periods of work and stochastic productivity shocks. I find that increasing ability or reducing fatigue does not lead necessarily to more productive efficiency,...

Let a society’s unhappiness be measured by the aggregate of the levels of relative deprivation of its members. When two societies of equal size, F and M, merge, unhappiness in the merged society is shown to be higher than the sum of the levels of unhappiness in the constituent societies when...

This is an entirely new draft of the fourth chapter of my book Foundations of Evolutionary Economics which is going to be published by Edward Elgar in due course. A full summary of chapter four can be found at the beginning of the main text. The chapter argues that the evolutionary notion of the...

This article describes, within a microeconomic intergenerational bargaining framework incorporating two discrete periods and binary states of risks, some new aspects regarding the mixture of intergenerational risk sharing and social security. Here, state-dependent utility under mortality risk...

This paper provides a tractable theoretical model designed to capture the targeting incentives created by benchmark testing. Under high-stakes benchmark testing, schools and teachers are judged on the fraction of students that meet some given level of educational attainment. The incentive for...

Compensated demand functions are useful tools to calculate and manipulate not only equivalent and compensating variations, but also ordinary demand functions. As a bonus I will show that the CES utility function admits welfare analysis without computer aid, contrary to the suggestion of Tohamy...

This chapter makes three fundamental points about law and economics. First, although some people feel strong, negative emotional reactions to utilizing microeconomics to analyze non-business areas of law, others feel no such emotional reactions. This chapter advances the hypothesis that people...
