Közbeszerzésnek ebben a cikkben egy oszthatatlan jószág vásárlását nevezzük, ahol, noha a vásárló jólétét a termék minősége utólag befolyásolja, azt előre nem lehet szerződésbe foglalni, s így számon kérni sem. Megmutatjuk, hogy ilyenkor egyfajta korlátozott árverés...

problémáiknak, amelyeknek több évtizedre visszanyúló hagyományai vannak a modern közgazdaságtanban is. A magyar nyelvű szakirodalomban azonban sajátos módon kevés ilyen témájú elméleti munkát olvashatunk. A tanulmány röviden áttekinti a kiinduló dilemmához kapcsolódó...

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...

In traditional game theory, strategies are equivalent with actions and mixed strategies are the only extension. As a new extension, strategies are interpreted as plans. Although most plans are not very interesting (like doing a certain action), some conditional plans are. For example, they...

This paper studies optimal monetary and fiscal policies in an economy à la Lucas and Stokey (1983) and Lagos and Wright (2005) with multiple cash and credit goods. We show that optimal policies are in general time inconsistent due to insufficient number of instruments to influence future...

The rejection of unfair proposals in ultimatum games is often quoted as evidence of other-regarding preferences. In this paper we focus on those responders who accept any proposals, setting the minimum acceptable offer (MAO) at zero. While this behavior could result from the randomization...

This paper investigates the stability of agreements for sharing fish stocks among coastal states when migrations patterns change — a heretofore largely unexplored topic. The case investigated is the agreement on sharing the mackerel stock (<italic>Scomber scombrus</italic>) in the North-east Atlantic Ocean....

Game-theoretic models of fisheries typically consider cases where some players harvest a single common fish stock. However, these types of models do not capture many real-world mixed fisheries, where species can be biologically independent or dependent. The present paper considers cases where...

In this paper, we introduce a generalized version of impulse balance equilibrium. The stationary concept is applied to 3 × 3 games based on the Bailiff and Poacher Game (Selten, 1991) and its predictive success is experimentally tested against the one of Nash equilibrium. Experiments with 26...

Fisheries economics stand on the cusp of potentially sizeable changes in orientation and policy focus, leading in turn to comparable changes in modeling and general analysis. Notably, fisheries are increasingly framed as part of the overall marine environment rather than considered as solely or...
