The weak government argument claims that fractionalized governments (coalition or minority governments) have more difficulty increasing their tax revenues or decreasing their spending than majority governments. This implies that weaker governments are associated with higher government deficits. In this paper, we test the implication of a fractionalization effect within the optimum financing mod...

We study the relationship between participation in free trade agreements (FTAs) and the sustainability of democracy. Our model shows that FTAs can critically reduce the incentive of authoritarian groups to seek power by destroying protectionist rents, thus making democracies last longer. This gives governments in unstable democracies an extra motive to form FTAs. Hence, greater democratic insta...

Choice functions on tournaments always select the maximal element (Condorcet winner), provided they exist, but this property does not hold in the more general case of weak tournaments. In this paper we analyze the relationship between the usual choice functions and the set of maximal elements in weak tournaments. We introduce choice functions selecting maximal elements, whenever they exist. Mor...

The profiles of narrow lattice solitons are calculated analytically using perturbation analysis. A stability analysis shows that solitons centered at a lattice (potential) maximum are unstable, as they drift toward the nearest lattice minimum. This instability can, however, be so weak that the soliton is “mathematically unstable” but “physically stable”. Stability of solitons centered at a latt...

one of the thinkers¨ demands for governments is to take due care of the social rights of citizens thus far. no doubt, imam `ali (a.s.), as a muslim ruler, concentrated on maintaining man¨s rights both in theory and in practice. this article refers to the relationship between the right and the duty from imam ali¨s viewpoint, studies the foundations of man¨s rights and duties and discusses imam a...

this paper employs a multivariate dynamic conditional correlation garch model, which is developed by engle (2001, 2002), to detect the timing and nature of changes in the comovement between iranian output and prices for the periods after iran–iraq war , known as imposed war . the results showed that there is a weak correlation between output and prices after imposed war and  varies periodically...
