A magyar kártérítési jog egyik specialitása a fordított bizonyítási teher, azaz nem a károsultnak kell bizonyítania, hogy a károkozó nem az elvárható gondossággal járt el, hanem a károkozónak, hogy igen. Más országok jogrendszerében sem ismeretlen ez a szabály, de inkább...

A tanulmány bemutatja, hogy a módszertani individualizmus feltevésével élve és az ismételt játékok apparátusát alkalmazva, a jelenlegi társadalombiztosítási nyugdíj rendszerek többszörös fogolydilemma-játék típusú helyzetben vannak. Ennek jellem zésére a tanulmányban...

It is found that the “Theory of Moves” is adequate in a Cold War scenario, with functionally equal participants, such as the Cuban Missile Crisis. The destabilization of normal incentive systems, under power and information asymmetry, is what prevents an equilibrium from being reached, as...

La première partie propose une revue de littérature sur les jeux de congestions et les jeux de potentiel exact. La deuxième partie traite les jeux de congestion à choix unique dans le cas symétrique et propose une formule simple et pratique permettant de trouver l'ensemble de tous les...

We investigate experimentally whether the extent of conditional cooperation in public good games depends on the marginal per capita return (MPCR) to the public good and type of game. The MPCR is varied from 0.2 to 0.4 to 0.8. The ‘standard’ game, in which three players contribute before a...

This paper compares the ability to select the efficient policy of a parliamentary and a presidential constitutional setup. In order to do it we build a dynamic theoretical model with asymmetric information that succeeds in addressing both the politicians accountability and the competence...

In this paper we analyze how rati cation uncertainty impacts the optimal terms of international environmental agreements (IEAs). We relax the frequent assumption of countries as unitary actors by modeling the rati cation stage through uncertain preferences of a ratifying agent (e.g. the pivotal...

We allow a contest organizer to bias a contest in a discriminatory way; i.e., she can favor specific contestants by designing the contest rule in order to maximize total equilibrium effort (resp. revenue). The two predominant contest regimes are considered, all-pay auctions and lottery contests....

In using their citizen candidate framework, Besley and Coate (2001) fi nd that if citizen candidates with sufficiently extreme preferences are available, lobbying has no in fluence on equilibrium policy. I show that this result does not hold in a model with ideological parties instead of citizen...

This paper investigates the effects of different prize structures on the effort choices of participants in two-stage elimination contests. A format with a single prize is shown to maximize total effort over both stages, but induces low effort in stage 1 and high effort in stage 2. By contrast, a...
