One of the critical issues that face the accounting profession today involves choosing among alternative accounting information modes. This dissertation provides comparative empirical evidence on the predictive power of accrual-based accounting signals versus cash-flow accounting signals versus both of these signals jointly. The empirical hypotheses compare the degrees of association between the market evaluative criteria, market beta and security price behavior, and the different accounting signals. The research methodology employed includes the following. 1. Market beta and changes in security prices are used as the evaluative criteria. 2. Two regression models are developed and used to test the predictive power of the alternative accounting signals. 3. Several specifications for each model are used. These specifications are simple regression, multiple regression, interaction effect, partial correlation, incremental correlation, and time series and cross sectional analysis.

The objective of this research is to make a theoretical and empirical investigation into the application of a cashflow accounting system. The theoretical investigation provides a definition for cash-flow accounting; it also examines the major arguments for a cash-flow reporting system. Three hypotheses are proposed for testing. The first states that during periods of changing prices, performance indicators that are based on the conventional accrual accounting will diverge from performance indicators that are based on cash-flow accounting and will continue to diverge over time. The second states that this divergence will disappear if the effects of inflation are partialled out. The third states that cash-flow statements, properly interpreted, will enable users to predict business failure.

This research was designed to investigate the relationship between audit risk and the conduct of the audit engagement in the specific context of an oil and gas audit. Because reserve estimates are in the financial reports of oil and gas entities (in the depreciation, depletion and amortization calculation, the limitation on capitalized costs for companies using the full-cost method, and the required supplementary disclosure for companies subject to Securities and Exchange Commission requirements) and because the reserve estimation process is considerably affected by numerous factors, there is a chance that a material error could be incorporated into the financial statement representations with which the auditor is associated. The objective of the research was to (1) identify conditions which are important in an assessment of audit risk in associating with reserve estimates, and (2) determine the impact of some of these conditions on the conduct of the audit.
