Abstract Since Paul Samuelson introduced the theory of revealed preference, it has become
one of the most important concepts in economics. This chapter surveys some recent …

Revealed preference theory is brought to bear on the problem of recovering approximate
parametric preferences from consistent and inconsistent consumer choices. We propose …

Revealed preference theory is a domain within economics that studies rationalizability of
behavior by (certain types of) utility functions. Given observed behavior in the form of choice …

A contemporary research agenda in behavioral economics and neuroeconomics aims to
identify individual differences and (neuro) psychological correlates of rationality. This …

We report on two novel choice experiments with real goods where subjects in one treatment
are forced to choose, as is the norm in economic experiments, while in the other they are not …

Economic analysis assumes that consumer behaviour can be rationalised by a utility
function. Previous research has shown that some consistency of choices with economic …

Two individuals are said to be revealed different if their joint decisions are more distant from
rationality than either of their individual decisions taken separately. We show that the …

As large language models (LLMs) become integrated to decision-making across various
sectors, a key question arises: do they exhibit an emergent" moral mind"-a consistent set of …

Rationality is a fundamental pillar of Economics. It is however unclear if this assumption
holds when decisions are made under stress. To answer this question, we design two …

We provide a nonparametric revealed preference approach to demand analysis based on
homothetic efficiency. Homotheticity is widely assumed (often implicitly) because it is a …
