Sztochasztikus csődjátékok - avagy hogyan osszunk szét egy bizonytalan méretű tortát? = Stochastic bankruptcy games. How can a cake of uncertain dimensions be divided?

A kooperatív játékelmélet egyik legjelentősebb eredménye, hogy számos konfliktushelyzetben stabil megoldást nyújt. Ez azonban csak statikus és determinisztikus környezetben alkalmazható jól. Most megmutatjuk a mag egy olyan kiterjesztését - a gyenge szekvenciális magot -, amely képes valós, dinamikus, bizonytalan környezetben is eligazítást nyújtani. A megoldást a csődjátékok példájára alkalmazzuk, és segítségével megvizsgáljuk, hogy a pénzügyi irodalom ismert elosztási szabályai közül melyek vezetnek stabil, fenntartható eredményre. _______ One of the most important achievements of cooperative game theory is to provide a stable solution to numerous conflicts. The solutions it presents, on the other hand, have been limited to situations in a static, deterministic environment. The paper examines how the core can be extended to a more realistic, dynamic and uncertain scenario. The bankruptcy games studied are ones where the value of the estate and of the claims are stochastic, and a Weak Sequential Core is used as the solution concept for them. The author tests the stability of a number of well known division rules in this stochastic setting and finds that most are unstable, except for the Constrained Equal Awards rule, which is the only one belonging to the Weak Sequential Core.

“An Ebbing Tide Lowers all Boats” How the great recession of 2008 has affected men and women in Central and Eastern Europe

In this paper we explore the impact of the economic recession of 2008 on gender inequality in the labor force in Central and Eastern European countries. We argue that job and occupational segregation protected women’s employment more than men's in the CEE region as well, but unlike in more developed capitalist economies, women’s level of labor force participation declined and their rates of poverty increased during the crisis years. We also explore gender differences in opinions on the impact of the recession on people’s job satisfaction. For our analysis we use published data from EUROSTAT and our own calculations from EU SILC and ESS 2010.
