Cerreia-Vioglio, Ghirardato, Maccheroni, Marinacci and Siniscalchi (Economic Theory, 48:341-375, 2011) have recently proposed a very general axiomatisation of preferences in the presence of ambiguity, viz. Monotonic Bernoullian Archimedean (MBA) preference orderings. This paper investigates the...

In this paper the concepts of manipulation as strategic voting (misrepresentation of true preferences) and strategic nomination (by adding, or removing alternatives) are investigated. The connection between Arrow's and Gibbard-Satterthwaite theorems is discussed from the viewpoint of dilemma...

In this paper we provide two simple new versions of Arrow's impossibility theorem, in a model with only one preference profile. Both versions are transparent, requiring minimal mathematical sophistication. The first version assumes there are only two people in society, whose preferences are...

Through their writing, people often reflect their values. Since the 1970s, academic economists have gradually changed their third-person pronoun choices, from using the masculine form to incorporating feminine and plural forms. We document this transition empirically, and examine the role of...

Ein Finanzparlament oder vergleichbares Gremium anderen Namens würde finanzielle Entscheidungen treffen oder zumindest kontrollieren für seine jeweilige Organisation, sei diese ein Staat, eine internationale Vereinigung oder ein Verein. Stimmrechte für ein Finanzparlament würden nicht nach...

Freiwilliges Engagement findet in Deutschland in einem breiten Spektrum von Bereichen und Tätigkeitsfeldern statt. Gleichzeitig ist aber über die Tätigkeiten, die freiwillig Engagierte ausüben und deren quantitative Verteilung wenig bekannt. Dieser Beitrag verfolgt daher das Ziel, die...

We consider the problem of allocating multiple units of an indivisible object among a set of agents and collecting payments. Each agent can receive multiple units of the object, and has a (possibly) non-quasi-linear preference on the set of (consumption) bundles. We assume that preferences...

The literature on happiness shows that there are many factors that influence a person’s happiness. Extending previous studies, we investigate the role of the freedom of choice as a key contributing construct in influencing a person’s happiness. We define two hypothetical sub-constructs for...

We develop a formula for the optimal size of a joint savings association between individuals who share the same financial goal and who can save towards that goal at the same rate. Our motivating example and the core of our analysis is a Rotating Savings and Credit Association (ROSCA). We measure...
