We specify and compute equilibria of a dynamic policy-making game between a president and a legislature under insitutional rules that emulate those of the US Constitution. Policies are assumed to lie in a two-dimensional space in which one issue dimension captures systemic differences in partisan preferences, while the other summarizes non-partisan attributes of policy. In any period, the polic...

Experimental research shows that while most voters have some form of spatial preferences, individuals differ in the type of spatial preferences they have: many voters prefer candidates closer to themselves in a policy space (proximity voting), others prefer candidates that are simply on the same side of an issue as themselves (directional voting), and still others prefer those who will move pol...

The paper presents a tool for the creation of an electronic dictionary of multi-word proper names. Toposław uses graphs for the representation of inflectional and pragmatic variants of names. It cooperates with Morfeusz, a morphological analyser and generator for Polish words, and Multiflex, a cross-language morpho-syntactic generator of multi-word units. Our goal was to create a userfriendly t...

Different theories about the impact of aid make distinct predictions about citizens’ attitudes toward foreign aid in recipient countries. We investigate their preferences toward aid and government projects in order to examine these different theories. Are citizens indifferent between development projects funded by their own government or by foreign aid donors? To address this, in an experiment ...

UNLABELLED Acoustic vocal analysis is a simple and fast method that allows to differentiate normal from changed voices. There are few studies that analyze normal acoustic vocal parameters at different age ranges in children. AIMS To establish normative acoustic parameters of children's voice aged 4 to 12 years. METHODS Two hundred and forty children were divided into four sub-groups by age:...

The paper presents a complete information model of bidding in second price sealed bid and ascending price (English) auctions, in which potential buyers know the unit valuation of other bidders and may spitefully prefer that their rivals earn a lower surplus. Bidders with spiteful preferences should overbid in equilibrium when they know their rival has a higher value than their own, and bidders ...

Transitivity is the assumption that if a person prefers A to B and B to C, then that person should prefer A to C. This article explores a paradigm in which Birnbaum, Patton and Lott (1999) thought people might be systematically intransitive. Many undergraduates choose C = ($96, .85; $90, .05; $12, .10) over A = ($96, .9; $14, .05; $12, .05), violating dominance. Perhaps people would detect domi...

For assignment problems where agents, specifying ordinal preferences, are allocated indivisible objects, two widely studied randomized mechanisms are the Random Serial Dictatorship (RSD) and Probabilistic Serial Rule (PS). These two mechanisms both have desirable economic and computational properties, but the outcomes they induce can be incomparable in many instances, thus creating challenges i...

This paper considers the well studied problem of the existence of an undominated point, under the assumption of lexicographic preferences of voters, as espoused by Taylor in [24]. We extend Taylor's model to situations were we allow for (i) voters to have different ranings of the issues in ndimensional issue space and (ii) a candidate to be disregarded by a voter if his stand on any one or more...
