In decision usefulness theories, the emphasis of decision-makers would mean undertaking research that seeks to determine the information needs of decision-makers. This is because the primary goal of these theories is to provide information that is useful for making decisions.

The decision usefulness approach focuses on the users of financial information and their needs. Therefore, it would not involve research that does not consider users of accounting in the analysis. This approach is user-oriented, meaning it is designed to meet the specific needs of the users of the financial information.

The decision usefulness theories would also not involve research that provides solutions to the moral hazard problems without understanding the needs of the users. This is because understanding the needs of the users is a fundamental aspect of these theories.

Lastly, while the decision usefulness theories could involve undertaking research that seeks to determine the information needs of the public, this would not be the primary emphasis. The main focus is on the needs of the specific users of the financial information, rather than the public in general.
