Nash implementable domains for the Borda count

We characterize the preference domains on which the Borda count satisfies Maskin monotonicity. The basic concept is the notion of a "cyclic permutation domain" which arises by fixing one particular ordering of alternatives and including all its cyclic permutations. The cyclic permutation domains are exactly the maximal domains on which the Borda count is strategy-proof when combined with every possible tie breaking rule. It turns out that the Borda count is monotonic on a larger class of domains. We show that the maximal domains on which the Borda count satisfies Maskin monotonicity are the "cyclically nested permutation domains" which are obtained from the cyclic permutation domains in an appropriately specified recursive way. ------ *We thank József Mala for posing the question of Nash implementability on restricted domains that led to this research.

Islamist movements at crossroads: the choice between ideology and context-driven approach to politics. Case study on the Hashemite Kingdom of Jordan

The aim of the paper is to analyse the ongoing transformation process within the Islamist movements using the example of the moderate Islamic Action Front party in Jordan. The dilemma of participation in the 2010 general elections raised tensions between the Muslim Brotherhood in Jordan and its political wing, the Islamic Action Front, and between doves and hawks of the same organizations. Internal debate on the future has started recently among different groups within the Islamist movement in Jordan. The research is based on the author‘s recent field experience in Jordan (April–July 2010, Andrew W. Mellon Fellowship at the American Centre of Oriental Research, Amman, Jordan). The author also conducted research in Syria, Lebanon, Palestine and Egypt, where several interviews were carried out with leading and lower level Islamist politicians. The dynamic changes within Islamic Action Front Party in Jordan and its relation with the regime has been used as reference point. The main question of the research was aa how the changing political and regional context shapes decisions of the Islamist with special attention to the acceptance of democratic values and human rights, political participation, and the meanings of Islamic values in the 21st century, possible cooperation with secular parties/movements/the regime.
