Purpose The purpose of this paper is to investigate country-level and firm-level determinants of within-country accounting comparability for 16 European Union countries plus the USA in the post-International Financial Reporting Standards adoption period. Design/methodology/approach The authors use ordinary least squares regression to test the hypotheses with a correction for heteroscedasticity. Findings The authors find that firms in countries with rules-based accounting, higher quality public auditor work environments, stricter enforcement of accounting standards and more reliance on equity-market financing have higher within-country comparability with each other. At the firm-level, the authors find that firms which are larger, engage in less earnings management, and have lower return-on-asset volatility have higher within-country comparability with each other. Research limitations/implications The authors use one measure of accounting comparability. Alternative measures of accounting comparability could test the hypotheses more completely. Practical implications The findings of the paper may help the regulators make more efficient policies to establish an efficient financial market within their country. Originality/value The paper is the first, to the authors’ knowledge, to identify country-level and firm-level determinants of within-country accounting comparability. It contributes to the accounting literature by completing the theory of international accounting comparability from the within-country perspectives, as prior literature focuses on the cross-country perspective of international accounting comparability.

Abstract:Is it possible to quantify the information content of accounting reports? If possible, then how? This study examines accounting as a classical communication system with the purpose of providing a framework with which to approach these fundamentally important questions. Information theory was established in the early-mid 20th century to describe the properties of classical communication systems. Applying concepts from this theory to an accounting context provides insight into the questions asked above. Specifically, a measure of the information content of financial statement numbers is developed from these information theory concepts. The measure is also applied to several large companies' earnings numbers and aids in predicting their price movements.

Austrian and Croatian Caucasian population data were generated for eight tetrameric STR loci amplified in a single multiplex reaction. Fluorescent detection was employed using the ABI Prism 310 Genetic Analyzer, the 377 DNA Sequencer (ABI) and the 373A DNA Sequencer (ABI). The loci analyzed were HUMvWFA31 (vWA), HUMTH01, HUMTPOX, HUMCSF1PO, D5S818, D13S317, D7S820 and D16S539 as part of the GenePrint PowerPlex multiplex system.
