This study examines the impact of accounting comparability on financial reporting quality and the extent to which financial statement users understand the implications of firms' accruals. We predict that comparability improves the information environment, which not only enhances the ability of...

This study examines the effects of a prominent principles-based standard (SFAS-142, Goodwill and Other Intangible Assets) on financial statement comparability. Using non-goodwill-intensive firms as our control group, we implement a difference-in-differences research design to examine how...

We first develop an efficient algorithm to compute Deltas of interest rate derivatives for a number of standard market models. The computational complexity of the algorithms is shown to be proportional to the number of rates times the number of factors per step. We then show how to extend the...

We demonstrate how to compute first- and second-order sensitivities of portfolio credit derivatives such as synthetic collateralized debt obligation (CDO) tranches using algorithmic Hessian methods developed in Joshi and Yang (2010) in a single-factor Gaussian copula model. Our method is correct...
