A note on numerical representations of nested system of strict partial orders
Qin, Dan - In: Games 12 (2021) 3, pp. 1-9
This note provides two numerical representations of a nested system of strict partial orders. The first representation is based on utility and threshold functions. We generalize the threshold representation of menu-dependent preferences by allowing the threshold to depend not only on the menu...

Preferences over social risk : does (group) size matter?
Morone, Andrea; Temerario, Tiziana - 2016
In this paper, we first replicated Harrison et al. (2012). Then, we studied if the group's size has an impact on group's risk aversion. In line with Harrison et al. (2012), our results confirm that no significant differences occur between individuals and groups risk aversion in three-person...

Individual and group preferences over risk : does group size matter?
Morone, Andrea; Nemore, Francesco; Temerario, Tiziana - 2017
In this paper we investigated group size impact on risk aversion when a majority rule is applied. Drawing on the widely used Holt and Laury’s (2002) lottery pairs, we observed a risky shift for both individual and groups regardless of their size. However, groups choices are shown to be closer...

Are 'true' preferences revealed in repeated markets? : an experimental demonstration of context-dependent valuations
Tufano, Fabio (contributor) - 2008
This paper reports a new and significant experimental demonstration that market participants adjust their bids towards the price observed in previous market periods when - by design - individuals' values should not be affiliated with the market price. This demonstration implies that market...

Framing and free riding : emotional responses and punishment in social dilemma games
Cubitt, Robin P. (contributor);  … - 2008
In this paper, we report an experimental investigation of the effect of framing on social preferences, as revealed in a one-shot linear public goods game. We use two indicators to measure social preferences: self-reported emotional responses; and, as a behavioural indicator of disapproval,...

Decision Process, Preferences Over Risk and Consensus Rule : A Group Experiment
Morone, Andrea - 2017
The recent literature on individual vs. group decisions over risk has brought about divergent results, mainly depending on the institutional rules through which groups take decisions. While some studies where group decisions relied on the majority rule showed no appreciable difference between...

Can Risk-Taking Preferences Be Modified? Some Experimental Evidence
Booth, Alison L.; Nolen, Patrick J. - 2021
We summarise our two sets of controlled experiments designed to see if single-sex classes within coeducational environments modify students’ risk-taking attitudes. In Booth and Nolen (2012b), subjects are in years 10 and 11, while in Booth, Cardona-Sosa and Nolen (2014), they are first-year...

The evolutionary stability of optimism, pessimism, and complete ignorance
Schipper, Burkhard - 2019
We provide an evolutionary foundation to evidence that in some situations humans maintain either optimistic or pessimistic attitudes towards uncertainty and are ignorant to relevant aspects of the environment. Players in strategic games face Knightian uncertainty about opponents' actions and...

Inferring preferences from choices under uncertainty
Kuzmics, Christoph - 2012
