The classical credibility theory proposed by Bühlmann has been widely used in general insurance applications. In this paper we propose a credibility theory via truncation of the loss data, or the trimmed mean. The proposed framework contains the classical credibility theory as a special case...

Fitting insurance loss data can be challenging because of their non-negativity, asymmetry, skewness, and possible multi-modality. Though many parametric models have been used in the actuarial literature, these difficulties call for more flexible models for actuarial applications. In this paper,...

Extant theories suggest that managers may use hedging either to alleviate underinvestment problems caused by costly external financing or to promote overinvestment by circumventing the scrutiny of external capital markets. We empirically investigate this issue using a hand-collected dataset of...

This paper examines the notion of strategic ignorance in an earnings management context. Managers possess less information about loans subjected to securitization and auditors are aware of this shortcoming. Consistent with managers exploiting their own ignorance strategically and using loan loss...

Studies suggest that, pursuant to the implementation of SFAS 133, even sophisticated users of financial statements find it difficult to comprehend earnings implications of hedging derivatives. Moreover, due to stringent hedge accounting requirements under these standards, many economic hedges do...

A data-adaptive multiscale spatial decomposition model is proposed to deal with skew-distributed data (eg, population or GDP). Relying on the filtering characteristics according to the bandwidth change of kernel smoothing, the parallel spatial kernel smoothing with different bandwidths is...

Although prior literature has documented a positive association between business risk and audit fees, it remains unclear whether, in addition to expending greater audit effort on riskier clients, auditors also charge a risk premium. This is an important issue because a risk premium is a...
