In this paper, we analyze differences in the timeliness of income recognition between U.S. and U.K. GAAP financial reporting regimes. Building on previous work area focus links current reported earnings past changes market value. light Basu [1997] present a formal model which response to value varies according whether change is good news or bad. This yields number insights with regard definition measurement conservatism. We also report evidence indicating that controlling for...

A definition of perturbations space-times in general relativity is proposed. The leads a natural way to concept gauge invariance, and an extension lemma Sachs (1964). Coupled equations governing linearized certain tetrad components scalar, electromagnetic, gravitational fields are derived by the use Geroch, Held & Penrose’s (1973) version formalism Newman Penrose (1962). It shown that these invariant if only unperturbed space-time vacuum algebraic type {22} or, equivalently, perturbation...

We discuss a type-{22} solution of the Einstein-Maxwell equations which represents field uniformly accelerating charged point mass. It contains three arbitrary parameters $m$, $e$, and $A$, representing mass, charge, acceleration, respectively. The is direct generalization Reissner-Nordstrom general relativity Born classical electrodynamics. external "mechanical" force necessary to produce acceleration appears in form timelike nodal two-surface extending from particle's world line infinity....

In this study we compare the timeliness and conservatism of reported earnings across U.S. U.K. GAAP regimes. We present a theoretical model differential speeds recognition good news bad news. This suggests informative relatively robust ways measuring dimensions in income recognition. The analysis shows importance distinguishing between delays reporting early news, when comparing Empirical results suggest that treatment extraordinary items is important assessing relative conservatism. degree...

Abstract The paper presents a new methodology for evaluating corporate voluntary disclosures in the annual report discussion section. Based on dataset of electronic reports and standard text analysis software package, we text-search large number at minimal (marginal) cost. resulting sample sizes are comparable to those employed studies based AIMR-FAF database. A major advantage our scoring system is that it adaptable particular requirements research project. We demonstrate importance this...

Abstract We extend the prior literature on biased disclosure decisions by examining whether, when and how managers bias tone of forward‐looking narratives. In order to measure we employ techniques manual content analysis aggregate positive, neutral negative statements into an overall tone.We then analyse frequency positive for firms with large impending year‐on‐year changes in sales operating profit margin, regress cross‐sectionally four managerial incentive variables that are unrelated...

ABSTRACT Using an international sample of 16 countries, this paper examines if analyst- and country-specific characteristics explain the variation in target price (TP) accuracy. We find that significant average TP accuracy across countries is due to differences accounting disclosure quality, origin legal system, cultural traits, IFRS regulation. also analysts exhibit differential persistent ability forecast prices accurately, which confirms some have superior forecasting ability.
