A repair of an inconsistent database is traditionally defined as a consistent database that differs from the inconsistent one in a “minimal way.” As there are often reasons to prefer one repair over another, researchers have introduced and investigated the framework of preferred repairs, where a priority relation between facts is lifted towards a priority relation between consistent databases, ...

A semilocal convergence analysis for directional Newton methods in n-variables is provided in this study. Using weaker hypotheses than in the elegant related work by Y. Levin and A. Ben-Israel and introducing the center-Lipschitz condition we provide under the same computational cost as in Levin and Ben-Israel a semilocal convergence analysis with the following advantages: weaker convergence co...

In this study, we use Stochastic Frontier analysis approach to estimate cost efficiency, economies of scale, and technological progress among Iranian banks from 1999 to 2012. The results show that there is a marked difference in cost efficiency before and after the recent financial sanctions against Iranian banking industry. Moreover, the results indicate that specialized government-owned banks...

Recent years have seen extensive investigation of the information aggregation properties of markets. However, relatively little is known about conditions under which a market will aggregate the private information of rational risk averse traders who optimize their portfolios over time; in particular, what features of a market encourage traders to ultimately reveal their private information thro...
