Os efeitos da demissão nas necessidades espirituais de ex-comissários de bordo da Varig

This dissertation intends to identify the effects of the demission in the Varig's ex-flight attendants' spirituals needs. For this study we did field research carried through 31 halfstructuralized interviews with dismissed Varig's flight attendants. The data had been treated quantitatively, making tables that allowed us to infer about the adhesion in what we searched measure, and qualitatively, using the analysis of the speech's method. The study identifies that many of the ex-flight attendants make distinction between the company in which they had worked and the one that today acts with the Varig's name and symbol. By this way, they preserve feelings of love, affection and absence about to the old Varig, directing the feelings of anger and rancor, or simply indifference, to the new Varig. It is also perceived in the study that the majority of the interviewed people show positive expectations related to the involvement with a new company in which they come to work.

Anticipatory effects in the FTSE 100 index revisions

This paper examines the price impact of trading due to expected changes in the FTSE 100 index composition. We focus on the latter index because it employs publicly-known objective criteria to determine membership and hence it provides a natural context to investigate anticipatory trading e ects. We propose a panel-regression event study that backs out these anticipatory e ects by looking at the price impact of the ex-ante proba-bility of changing index membership status. Our ndings reveal that anticipative trading explains about 40% and 23% of the cumulative abnormal returns of additions and deletions, respectively. We con rm these in-sample results out of sample by tracking the performance of a trading strategy that relies on the addition/deletion probability estimates. The perfor-mance is indeed very promising in that it entails an average daily excess return of 11 basis points over the FTSE 100 index.
