Finansal piyasalarda risk ölçüsü olarak kullanılan Riske Maruz Değer (VaR), belirli bir zaman periyodunda ve güven düzeyinde elde tutulan portföyün uğrayacağı maksimum kaybı para miktarı olarak ifade eder. VaR, portföyün mümkün kayıplarının istatistiksel ölçüsünü özetleyen tek bir rakam olma özelliği taşımaktadır. Bu nedenle, yönetici kadrolarının ortaya çıkan tek bir rakama bakarak riskin karşılanabilir olup olmadığına dair karar almalarına yardımcı olmakta, dolayısıyla riskten korunmalarını sağlamaktadır. Finansal raporlarda sunulma zorunluğu bulunan VaR, piyasalarda faaliyet gösteren kurumlar tarafından da geniş kabul görmektedir.

Bu kitap finansal risk ölçümünde kullanılan VaR hesaplama yöntemlerini hem teorik hem de uygulamalı olarak ele almaktadır. Ayrıca bölüm sonlarında yer alan VaR uygulamalarına ait R kodları kitabın sonunda okuyucuya sunulmaktadır. Kitapta bulunan konular ana başlıklar ile aşağıdaki gibidir:

This study, which is based on a PhD thesis; examines, with an integrative perspective, the effects of employees’ perceptions about the empowering behavior of their immediate supervisor on employees’ psychological empowerment, and the effects of employees’ psychological empowerment on their job satisfaction, extrinsic reward satisfaction, affective commitment towards their organizations, turnover intentions; and task performance and organizational citizenship behavior. In addition, this study makes comparisons between the strength of some of the hypothesized relationships.

The primary finding of the study is that there is a strong relationship between enhancing meaningfulness- providing autonomy dimension of empowering behavior of supervisors and employees’ psychological empowerment. Another important finding is that there are positive relationships between empowering behavior of supervisors and employees’ job satisfaction, extrinsic reward satisfaction, and affective commitment.

The results also indicate that the impact of empowerment on job satisfaction is stronger than that on extrinsic reward satisfaction, and the impact of job satisfaction on turnover intention is stronger than that of extrinsic reward satisfaction. Finally, there are negative influences of empowerment on employees’ task performance and organizational citizenship behavior.
