Based on extant literature, we review the positive theory of GAAP. The theory predicts that GAAP’s principal focus is on control (performance measurement and stewardship) and that verifiability and conservatism are critical features of a GAAP shaped by market forces. We recognize the advantage of using fair values in circumstances where these are based on observable prices in liquid secondary markets, but caution against expanding fair values to financial reporting more generally. We conclude that rather than converging U.S. GAAP with IFRS, competition between the FASB and the IASB would allow GAAP to better respond to market forces.

We review recent literature on the role of financial reporting transparency in reducing governance-related agency conflicts among managers, directors, and shareholders, as well as in reducing agency conflicts between shareholders and creditors, and offer researchers some suggested avenues for future research. Key themes include the endogenous nature of debt contracts and governance mechanisms with respect to information asymmetry between contracting parties, the heterogeneous nature of the informational demands of contracting parties, and the heterogeneous nature of the resulting governance and debt contracts. We also emphasize the role of a commitment to financial reporting transparency in facilitating informal multiperiod contracts among managers, directors, shareholders, and creditors.

Calls for eliminating differences between accounting earnings and taxable income in the US have been debated extensively. Proponents of increased book-tax conformity argue that tax compliance will increase and earnings quality will improve. Opponents argue that earnings quality will decline. We examine whether the level of required book-tax conformity affects earnings persistence and the association between earnings and future cash flows. We develop a comprehensive book-tax conformity measure and find that earnings have lower persistence and a lower association with future cash flows when conformity is higher. Our evidence suggests that increased book-tax conformity may reduce earnings quality.
