Accounting numbers are not only the products of peripheral economic events, but, by and large, can be consciously influenced from the effects of calculated business decisions and the selective applications of alternative reporting procedures. In academic parlance, the term accounting quality, or lack thereof, is often used to describe the extent to which these convoluting influences create a disparity between economic fundamentals and their numerical portrayal. This doctoral thesis speaks to three aspects of accounting quality; (i) Earnings Thresholds: A Re-Examination of the Role of Earnings Management, (ii) Earnings Manipulation and the Investigation of 'Red Flag' Accounting Ratios, and (iii) An Empirical Analysis of Standard and Poor's (S&Ps) Core Earnings metric. Each topic is outlined in a separate research paper.
