optimal capacitor placement, considering power system loss reduction, voltage profile improvement, line reactive power decrease and power factor correction, is of particular importance in power system planning and control. the distribution system operator calculates the optimal place, number and capacity of capacitors based on two major purposes: active power loss reduction and return on invest...

In the literature of data mining, many different algorithms for association rule mining have been proposed. However, there is relatively little study on how association rules can aid in more specific targets. In this paper, one of the applications for association rules maximal-profit item selection with cross -selling effect (MPIS) problem is investigated. The problem is about selecting a subse...

Standard auctions are known to be a revenue-maximizing way to sell an object under broad conditions when buyers are symmetric and have independent private valuations. We show that when buyers have interdependent valuations, auctions may lose their advantage, even if symmetry and independence of information are maintained. In particular, simple alternative selling mechanisms that sometimes allow...

The "endowment effect" refers to the tendency to place greater value on items that one owns-an anomaly that violates the reference-independence assumption of rational choice theories. We investigated neural antecedents of the endowment effect in an event-related functional magnetic resonance imaging (fMRI) study. During scanning, 24 subjects considered six products paired with 18 different pric...

The multitude of explanations for the January effect leaves the reader confused about its primary cause(s): is it tax-loss selling, window dressing, information, bid-ask bounce, or a combination of these causes? The confusion arises, in part, because evidence has generally been presented in support of a particular hypothesis though the same evidence may be consistent with another hypothesis. Fu...

This paper examines the “relative” information contained in insider director transactions. We find that insider transactions of multi-company directors reflect superior information about future relative returns; that is, directors are more likely to buy (sell) stocks of firms they direct that have better (worse) future returns. Examining related issues, we find weak support that December tax lo...
