This advanced textbook is an essential guide to discovering new and more illuminating
ways to analyse the econometric modelling of experimental data. Peter Moffatt, one of the …

Decisions to trust in strategic situations involve ambiguity (unknown probabilities). Despite
many theoretical studies on ambiguity in game theory, empirical studies have lagged behind …

Facing several decisions, people may consider each one in isolation or integrate them into a
single optimization problem. Isolation and integration may yield different choices, for …

The term 'preference imprecision'seems to have different meanings to different people. In the
literature, one can find references to a number of expressions. For example: vagueness …

This paper examines the difference between strategic ambiguity as in game theory and
ambiguity arising in individual decisions. We identify a new, non-strategic component …

We experimentally test for the role of choice uncertainty in generating “endowment effects”-
the robust empirical finding that endowing participants with an item raises their reported …

We introduce belief hedges, ie, sets of events whose uncertain subjective beliefs neutralize
each other. Belief hedges allow us to measure ambiguity attitudes without knowing those …

We report the results from an experiment designed to measure attitudes towards ambiguity
beyond ambiguity aversion. In particular, we implement recently-proposed model-free …

Keynes (1921) and Ellsberg (1961) have articulated an aversion toward betting on an urn
containing balls of two colors of unknown proportion to one with a 50–50 composition …

In random incentive mechanisms agents choose from multiple problems and a
randomization device selects a single problem to determine payment. Agents are assumed …
