Financial statements summarize a firm's fiscal position using only a limited number of accounts. Readers often interpret financial statements in conjunction with other information, some of which may be aggregated in a different way (or not at all). This paper exploits properties of the double‐entry accounting system to provide a systematic approach to reconciling diverse financial data. The key is the ability to represent the double‐entry system by network flows and, thereby, access well‐recognized network optimization techniques. Two specific uses are investigated: the reconciliation of audit evidence with management‐prepared financial statements, and the creation of transaction‐level financial ratios.

Firms’ reluctance at times to publicly disclose financial information is often attributed to concern that the information may be used against them by self‐interested outside parties. These outside parties may interact with the firm in the horizontal realm (e.g., retail competitors) or in the vertical arena (e.g., wholesale suppliers). This article is built on the premise that fully understanding the strategic consequences of disclosure requires joint consideration of horizontal and vertical relationships. When both rivals and suppliers are accounted for, we demonstrate that (i) lower intra‐industry correlation in product demand favors disclosure, with the precise correlation‐cutoff dependent on the firm's use of input suppliers; and (ii) the more a firm relies on input suppliers with pricing power, the less attractive is disclosure.

This paper extends a familiar model of competition and disclosure to incorporate the practical feature that firms may not only hold private information about consumer demand, but they can also influence demand by the investments they make in improving product quality. Such investments can reflect installing new product features, improving durability, adding design enhancements, and the like. This paper demonstrates that investments stand to significantly influence the firm's preference for disclosures and, in fact, become a determining feature of disclosure choice. In particular, under Cournot competition, a firm prefers disclosure when the industry‐wide effects of information and investments are concordant. That is, if both product quality and demand information have large positive industry spillovers, disclosure is desirable because it promotes implicit cooperation in investments; if both have low spillover, disclosure permits a firm to convey strength to a rival and then use quantity and quality in concert to dominate the market precisely when the firm's demand is at its peak.
