market efficiency and insider trading new evidence that corporate insiders earn profits from stock trading does not surprise most financial economists but that outsiders can earn abnormal returns by using pub licly available insider trading data constitutes a serious exception to stock market efficiency the authors show that this anomaly conti nues to exist despite the publication of studies attesting to its exi stence they suggest that the anomalous profits to outsiders are a ma nifestation of the size and earnings price ratio effects controlling for these factors reduces outsider profits by half the additional a ssumption of a 2 percent transactions cost makes outsider profits zer o or negative insider profits after an assumed 2 percent transactio ns cost are a moderate 3 percent per annum for annual holding period s copyright 1988 by the university of chicago

discretionary accounting choices and the predictive ability of accruals with respect to future cash flows using a sample of restatement firms and a meet or beat model to classify firms as making discretionary accounting choices for opportunistic meet or beat op mb reasons we show that originally reported earnings and accrual components are less predictive of future cash flows relative to the restated numbers we find the opposite is true for firms classified as making discretionary accounting choices for non op mb reasons we consider a number of competing explanations for these latter results our findings are most consistent with the informational hypothesis weakly consistent with conservative motivated efficient contracting hypotheses but inconsistent with opportunistic contracting and misapplication errors of gaap explanations

do stock investors value corporate sustainability evidence from an event study this paper analyzes the impacts of index inclusions and exclusions on corporate sustainable firms by studying a sample of us stocks that are added to or deleted from the dow jones sustainability world index over the period 2002 2008 the impacts are measured in terms of stock return risk and liquidity we cannot find any strong evidence that announcement per se has any significant impact on stock return and risk however on the day of change index inclusion exclusion stocks experience a significant but temporary increase decrease in stock return liquidity deteriorates after the announcement day and bounces back significantly near the day of change systematic risk shows little change after announce ments but idiosyncratic risk is higher after announcements the overall results support harris and eitan s the journal of finance41 4 815 829 1986 price pressure hypothesis which posits that event announcement does not carry information and any shift in demand and hence the corresponding price change and liquidity change is temporary

does meeting earnings expectations matter evidence from analyst forecast revisions and share prices this paper investigates whether the market rewards firms meeting current period earnings expectations and whether any such reward reflects the implications of meeting expectations in the current period for future earnings or reflects a distinct market premium we document that abnormal annual returns are significantly greater for firms meeting expectations controlling for the information in the current year s earnings we then test whether firms meeting expectations experience higher returns simply because their expected future earnings are also higher we find firms meeting expectations have significantly higher earnings forecasts and realized earnings than firms that do not we find that controlling for these higher future earnings firms meeting expectations in one or two years do not receive a greater valuation than their fundamentals would suggest we find however that the market assigns a higher value to firms that meet expectations consistently controlling for an estimate of the firm s fundamental value

mimickers of corporate insiders who make large volume trades most prior research shows that corporate insiders can systematically earn abnormal returns by buying or selling their own securities also several studies have investigated whether outsiders can earn abnormal returns by mimicking the trades of insiders after the latter report their trades the findings of these studies suggest that they cannot in contrast this study s results indicate that outsiders can earn significant abnormal returns by mimicking such trades this conclusion is consistent with a growing body of empirical literature that suggests that the market is not efficient in the semistrong form i e is not efficient with respect to all publicly available information

the effect of audit adjustments on earnings quality evidence from china we examine how adjustments to earnings during year end audits affect measures of earnings quality there are four key findings first audit adjustments cause earnings to become smoother and more persistent second the adjustments result in higher accrual quality third audit adjustments have a larger negative effect on signed accruals than absolute accruals fourth the adjustments do not reduce the discontinuity in the earnings distribution around zero these findings are of interest to researchers who use earnings properties as proxies for earnings quality and audit quality however we caution that our findings for china may not generalize to other countries

a direct test of roll s conjecture on the firm size effect empirical research indicates that small firms earn higher average rates of return than large firms even after accounting for beta risk roll conjectured that the small firm effect might be attributed to improper estimation of security betas the evidence shows that while the direction of the bias in beta estimation is consistent with roll s conjecture the magnitude of the bias appears to be too small to explain the firm size effect

is the well being of children converging in the european union recent discussion of convergence in the european union has focused on macroeconomic indicators in line with requirements for participation in the single currency but it is reduction of disparities in living standards that is an ultimate goal of european integration the greater economic and social cohesion emphasised by the treaty on union we assemble evidence on whether the well being of children in member states has been converging over the last two decades taking a variety of indicators poverty household worklessness youth unemployment child mortality youth suicide educational enrolment teenage fertility and self reported life satisfaction

earnings management and accounting income aggregation quarterly earnings allow aggregation into annual earnings in four different ways fiscal year earnings is one measure of annual earnings the others being earnings for annual periods ending at interim quarter ends we investigate earnings management in fiscal year earnings relative to these alternative measures of firms annual earnings we confirm prior findings in burgstahler and dichev 1997 earnings management to avoid earnings decreases and losses journal of accounting and economics 24 99 126 of discontinuities around zero and prior year earnings in histograms of earnings subsequent research questions whether these discontinuities are evidence of earnings management using histograms of our alternative annual earnings measures we offer evidence suggesting earnings management is responsible for the discontinuities

evidence that the zero earnings discontinuity has disappeared abstract discontinuities in earnings distributions at zero have been widely cited as evidence of earnings management but not without controversy recent research suggests discontinuities may be mere artifacts of certain research design choices we find that the well known zero earnings discontinuity disappears soon after passage of the sarbanes oxley act sox and has not returned we also find that neither the discontinuity nor its disappearance require the effects of widely cited alternative non earnings management explanations for the zero earnings discontinuity

the information content of losses abstract this study hypothesizes that because shareholders have a liquidation option losses are not expected to perpetuate they are thus less informative than profits about the firm s future prospects the results are consistent with the hypothesis they also show that the documented increase in the earnings response coefficent as the cumulation period increases appears to be due exclusively to the effect of losses the liquidation option effect extends to profitable cases where earnings are low enough to make the option attractive alternating explanations for the low informativeness of losses such as mean reversal of earnings are not supported by the tests

earnings management erroneous inferences based on earnings frequency distributions a vast literature following hayn 1995 and burgstahler and dichev 1997 attributed the so called discontinuities in earnings distributions around zero to earnings management despite recent evidence that these discontinuities are likely caused by other factors researchers and teachers continue to point to the shapes of these distributions as evidence of earnings management we provide three sets of further evidence that these discontinuities are likely caused by factors other than earnings management 1 we provide as an example a detailed analysis of the severe effects of sample selection in a recent study this study erroneously concludes that the shape of an earnings distribution is evidence of earnings management 2 we provide a simple explanation for the shape of the earnings distribution that is most often cited as evidence of earnings management the relation between earnings and prices differs with the magnitude and the sign of earnings and 3 we provide further examples that support the main point of our paper evidence beyond the mere shape of a distribution must be brought to bear before researchers can draw conclusions regarding the presence absence of earnings management

misspecification of capital asset pricing this study documents empirical anomalies which suggest that either the simple one period capital asset pricing model capm is misspecified or that capital markets are inefficient in particular portfolios based on firm size or earnings price e p ratios experience average returns systematically different from those predicted by the capm furthermore the abnormal returns persist for at least two years this persistence reduces the likelihood that these results are being generated by a market inefficiency rather the evidence seems to indicate that the equilibrium pricing model is misspecified however the data also reveals that an e p effect does not emerge after returns are controlled for the firm size effect the firm size effect largely subsumes the e p effect thus while the e p anomaly and value anomaly exist when each variable is considered separately the two anomalies seem to be related to the same set of missing factors and these factors appear to be more closely associated with firm size than e p ratios

a new approach to testing asset pricing models the bilinear paradigm we propose a new approach to estimating and testing asset pricing models in the context of a bilinear paradigm introduced by kruskal 18 this approach is both simple and at the same time quite general as an illustration we apply it to the special case of the arbitrage pricing model where the number of factors is pre specified the data appear to be generally in conflict with a five or seven factor representation of the model used by roll and ross 30 when we consider the number of replications of our test and the large number of observations on which it is performed the frequency with which we reject the three factor apm does not lead us to conclude that this model is unrepresentative of security returns further the rejection of the five and seven factor versions is to be expected if the three factor version is correct the paradigm gives insight into the appropriate specification of the model and suggests that there may be a small number of economy wide factors that affect security returns tests of asset pricing models on the basis of observed stock market data have represented a staple of the financial economics literature of the past twenty years the early work is reviewed in the famous paper by jensen 12 and papers by fama and macbeth 6 rosenberg and marathe 31 and roll and ross 30 there has been a great deal of confusion regarding what testable propositions are implied by these models see discussion in roll 29 in this paper we show that at a minimum all asset pricing models yet proposed imply a simple easily testable hypothesis which we refer to as the bilinear hypothesis while specific models may imply further testable propositions if the bilinear hypothesis is rejected the model is inconsistent with the data and should be rejected our test exploits the fact that the economic content of any equilibrium asset pricing model can be expressed in the form of a potentially refutable constraint on the set of parameters of the process generating security returns this constraint specifies that given a set of security specific characteristics there exists a linear relationship common across securities relating expected returns to these

are hedge fund managers systematically misreporting or not a discontinuity or kink at zero in the hedge fund net return distribution has been interpreted as evidence of managers manipulating returns to avoid showing small losses instead we propose alternative explanations for this phenomenon in particular we show that incentive fees can mechanistically create a kink in the net return distribution this mechanism accounts for almost the entire kink observed in the large liquid long short equity style furthermore we show that asset illiquidity and the bounding of yields at zero can generate distribution discontinuities as well therefore we conclude that the observed hedge fund return discontinuities are not direct proof of manipulation

convergence clubs and subsistence economies abstract this paper focuses on one possible explanation for the empirical evidence of a income convergence among the world s poorest countries and among its wealthiest countries and b income divergence among most of the remaining countries the model incorporates the assumption of subsistence consumption into the neoclassical exogenous growth model yielding outcomes that are consistent with the convergence divergence empirical evidence while subsistence consumption can lead to negative saving and disaccumulation of capital it can also coincide with positive saving and accumulation of capital the model predicts that the poorer the country the lower its saving rate a result that also appears to be borne out by the evidence provided here

earnings quality evidence from the field abstract we provide insights into earnings quality from a survey of 169 cfos of public companies and in depth interviews of 12 cfos and two standard setters cfos believe that i above all high quality earnings are sustainable and repeatable specific characteristics include consistent reporting choices backing by actual cash flows and absence of one time items and long term estimates ii about 50 of earnings quality is driven by non discretionary factors such as industry and macro economic conditions iii in any given period about 20 of firms manage earnings to misrepresent economic performance and for such firms 10 of eps is typically managed iv earnings manipulation is hard to unravel from the outside but peer comparisons and lack of correspondence between earnings and cash flows provide helpful red flags in addition cfos disagree with current standard setting on a number of issues including the sheer number of promulgated rules the top down approach to rule making the neglect of the matching principle and the emphasis on fair value accounting they indicate that a rules based culture makes the audit function centralized and mechanical and hinders the development of audit professionals a summary impression from our work is that cfos view earnings quality as more of a single and unconditional characteristic in contrast to current research where measures of earnings quality are strongly conditional on the decision setting this cfo view is related to their idea of one number a single earnings metric that shapes both their interactions with external stakeholders and internal decision making

investment dynamics and earnings return properties a structural approach we propose the standard neoclassical model of investment under uncertainty with short run adjustment frictions as a benchmark for earnings return patterns absent accounting influences we show that our proposed benchmark generates a wide range of earnings return patterns documented in accounting research notably our model generates a concave earnings return relation similar to that of basu 1997 and predicts that the earnings return concavity increases with the volatility of firms underlying shock processes and decreases with the level of firms investments we find strong empirical support for these predictions overall our evidence suggests that our proposed benchmark is useful for understanding the joint dynamics of variables of interest to accounting research e g earnings returns investment market to book absent accounting influences a necessary precondition for inferring the effects of accounting from these dynamics

do scaling and selection explain earnings discontinuities abstract earnings distributions commonly exhibit statistically significant discontinuities at zero earnings which are widely interpreted as evidence of earnings management to avoid a loss in contrast durtschi and easton 2005 durtschi and easton 2009 assert that discontinuities are instead explained by some combination of prior researchers choice s of scaling and sample selection as well as a scaling related effect due to a systematic relation between the sign of earnings and market prices resolution of the conflicting interpretations of discontinuities is important because 1 it affects how investors regulators and scholars view earnings management and 2 it demonstrates the importance of a close linkage between theory and research design choices we point out that de provide no evidence that scaling or selection create discontinuities but only evidence showing that changes in scaling or selection eliminate discontinuities we demonstrate why the research designs used by de eliminate discontinuities and why alternative designs using the same data yield statistically significant discontinuities that cannot be attributed to either scaling or selection

biased forecasts or biased earnings the role of reported earnings in explaining apparent bias and over underreaction in analysts earnings forecasts the extensive literature that investigates whether analysts earnings forecasts are biased and or inefficient has produced conflicting evidence and no definitive answers to either question this paper shows how two relatively small but statistically influential asymmetries in the tail and the middle of distributions of analysts forecast errors can exaggerate or obscure evidence consistent with analyst bias and inefficiency leading to inconsistent inferences we identify an empirical link between firms recognition of unexpected accruals and the presence of the two asymmetries in distributions of forecast errors that suggests that firm reporting choices play an important role in determining analysts forecast errors r 2003 elsevier b v all rights reserved

firless firwoes how preferences can interfere with the theorems of international trade abstract an example is presented of a two country two factor four good trade model in which free trade causes factor prices to be drawn farther apart than they were in autarky the example is equivalent to a two good model with a double factor intensity reversal fir and thus demonstrates that the problems associated with firs can arise in many dimensions without them these problems include the undermining of other trade theorems as well and can be avoided only by making some assumption about demand as well as about technology for example the model becomes well behaved if preferences and technology are both cobb douglas

price convexity and skewness this paper develops a model in which investors who are prohibited from short selling agree to disagree on the precision of a publicly observed signal the model implies that the equilibrium price is a convex function of the public signal the model predicts that 1 the stock price reacts more to good news than to bad news 2 the skewness of stock returns is positively correlated with contemporaneous returns but negatively correlated with lagged returns 3 short sale constraints increase rather than decrease skewness and 4 disagreement about information precision increases skewness empirical tests conducted find supportive evidence for all these predictions

earnings management to avoid earnings decreases and losses this paper provides evidence that firms manage reported earnings to avoid earnings decreases and losses specifically in cross sectional distributions of earnings changes and earnings we lind unusually low frequencies of small decreases in earnings and small losscs and unusually high frequencies of small increases in earnings and small positive income we find evidence that two components of earnings cash flow from operations and changes in working capital are used to achieve increases in earnings we present two theories based on stakeholder use of information processing heuristics and prospect theory about the motivation for avoidance of earnings decreases and losses

anomalies in security returns and the specification of the market model we examine the hypothesis originally advanced by roll 12 that observed anomalies in excess returns can be explained by misspecification of the market model used to estimate systematic risk we find substantial misspecifications in the model systematically related to size and period of listing of the securities in question there is some evidence that these misspecifications are associated with systemic biases in measured betas used to construct excess returns

what does ceos pay for performance reveal about shareholders attitude toward earnings overstatements if overstatements were a symptom of the agency conflict pay for performance sensitivities should have increased in response to the additional penalties for misreporting imposed by sox our finding of their decrease is inconsistent with the view that overstatements were an unintended consequence of incentive pay prior to 2002 to corroborate our interpretation we show that i ceo pay for performance sensitivities are higher among firms whose shareholders stand to benefit from overstatements ii this cross sectional relationship weakens significantly after sox and iii the within firm decrease in pay for performance sensitivity is most pronounced among firms with high pre sox shareholder benefits from overstatements

convergence clubs and endogenous growth recent data indicate a wide disparity in the growth performance of different nations such disparities have usually been taken to imply that there is to much catching up or convergence taking place using a modified version of the endogenous growth approach we show that convergence is occurring but in a non equalizing manner the world appears to be segmented into two mutually exclusive convergence clubs with the members of the richer club enjoying a real income per capita which is significantly higher than that enjoyed by those belonging to the poorer club copyright 1992 by oxford university press

performance standards and optimal incentives abstract this paper analyzes incentive design when agents effort influences an uncertain output governed by a random process with semi heavy tails we find that the second best incentive contract pays an output increasing but bounded fee with a shape resembling performance standard contracts that pay a fixed salary plus a capped bonus in this contract the pay performance sensitivity around the standard increases decreases with the frequency with which performance is measured and with the kurtosis volatility parameter of the performance probability distribution we also find that the optimal maximum bonus increases with volatility but decreases with the kurtosis parameter of the performance distribution

earnings management the shapes of the frequency distributions of earnings metrics are not evidence ipso facto we provide evidence that the shapes particularly around zero of the frequency distributions of earnings metrics examined in the extant earnings management literature are affected by 1 deflation using for example price or market capitalization 2 sample selection criteria that lead to differential inclusion exclusion of observations to the left of zero versus observations to the right of zero implicit in studies focusing on firms followed by i b e s and explicit in studies partitioning on a variable differing between loss observations and profit observations 3 differences between the characteristics of observations to the left of zero and observations to the right of zero such as market pricing and analyst optimism pessimism or 4 a combination of these factors since the shapes of the frequency distributions of earnings metrics at zero are likely due to one of the above effects we conclude that the shapes cannot be used as ipso facto evidence of earnings management
