stock price reactions as surrogates for the net cash flow effects of corporate policy decisions abstract this paper adopts a rational market structure to examine the link between the cash flow effects of management policy decisions and the resulting stock price reactions the focus is on testing cross sectional associations between cash flow effects and the underlying characteristics of affected firms we find that it is not possible to infer the sign of association between the stock price reaction and any characteristics of the firm that are observable before management announces its decision our methodological suggestions involve exploiting either a priori assumptions or sample information about the probability distribution of unobservable decision variables underlying the management decision process

information sharing in dea a cooperative game theory approach abstract in this paper a cooperative dea game is proposed based on the idea that different organizations can gain if they share data on the input consumption and output production of their processing units a larger data sample allows a more complete description of the production possibility set and consequently of the efficient frontier however since not all organizations will benefit in the same way it is convenient to use cooperative game theory in order to share the benefits of the cooperation the proposed cooperative dea game is shown to be subadditive and balanced models for computing the value of the game and checking its stability taking into account the exponential number of coalitions that exist when the number of organizations is large are also presented the approach is illustrated with a dataset from the literature

the forecasting approach to efficiency in the wool market this paper develops and presents estimates of a simultaneous equations model of the australian wool market the world s largest producer and exporter of fine wool the model contains functional relationships for unhedged inventories consumption of raw wool and the activities of both hedgers and speculators in wool futures expectations are represented by the adaptive hypothesis this model extends the work of leuthold and hartmann 1979 and leuthold and garcia 1988 by including expectations in the spot futures model and that of goss and giles 1986 by including composite equations for hedger speculators extending the expectations hypothesis to the consumption equation and by using the model to test the efficient markets hypothesis wald tests and likelihood ratio tests for unit roots in wool cash prices are conducted and in no case can the hypothesis of a single unit root be rejected estimation is by three stage least squares with correction for first order serial correlation the model provide

the information content of security prices a second look abstract beaver lambert and morse 1980 employ a regression of percentage change in prices on percentage change in earnings in which data are grouped by the dependent variable reverse regression offers a more intuitive and direct way to assess the information content of security prices the objective of beaver et al while grouping is asymptotically equivalent reverse regression is a more efficient way of examining the incremental explanatory power of lagged values of percentage change in price with respect to accounting earnings

do nonlinearity firm specific coefficients and losses represent distinct factors in the relation between stock returns and accounting earnings abstract recent studies have provided theory and evidence that the contemporaneous relation between stock returns and accounting earnings is nonlinear different for profits and losses and different across firms since each factor can result from differences in earnings persistence existing theory is ambiguous as to whether these factors are distinct or overlapping thus we conduct a simultaneous examination our primary tests show that each factor explains a significant portion of the variance of returns after controlling for the other two factors with firm specific estimation providing the largest incremental explanatory power alternative tests produce similar conclusions empirically the three factors are distinct

stock price reactions to lifo adoptions the association between excess returns and lifo tax savings although long a topic of accounting research little is known about the motives for or effects of voluntary changes in accounting techniques among the motives which have been suggested are attempts by managers to smooth reported earnings gordon 1964 copeland 1968 cushing 1969 white 1972 and ronen and sadan 1981 to influence man agement compensation to reduce regulatory or political costs watts and zimmerman 1978 and to avoid bond covenant restrictions holthausen 1981 while some of these motives may be consistent with a market value rule they often fail to provide unambiguous accounting change predictions e g which accounting changes result in lower regulatory costs moreover empirical verification has been constrained by the unobservability of the variables to which the managers allegedly respond the stock price reaction which should be expected for a given account ing change depends not only on its implications for the valuation of securities but also on the extent to which the implications are already known or anticipated by investors 3 ultimately our ability to detect these stock price effects if any depends on the power of our tests previous studies of the effects of accounting changes have generally not found significant stock price reactions archibald 1972 ball 1972 kaplan and roll 1972 harrison 1977 and holthausen 1981 4 for the most part these studies dealt with accounting changes which had no direct cash flow effects in contrast changes in inventory costing methods especially those involving the last in first out lifo cost flow assumption can generate potentially large changes in a firm s cash flows due to their impact on taxable earnings these cash flow effects provide not only a motive for lifo changes5 which is consistent with the market value rule but also implications for associated stock price effects if investors react to lifo s cash flow implications rather than to its effects on reported earnings then positive stock price adjustments should be associated with lifo adjustments however the evidence from previous studies of stock price reactions to lifo adoptions is inconclusive ball 1972 sunder 1973 1975 abdel khalik and mckeown 1978 brown 1980 and ricks 1982 while several factors may account for these results see section 2 it can be noted that the previous studies have considered only a dichotomous variable whether or not a firm has adopted lifo yet because the cash flow consequences of a lifo adoption decision depend on a number of firm specific factors this approach ignores potentially large differences among firms in the economic consequences of lifo adoptions most firms switching to lifo now reveal in their financial statement disclosures the tax savings which have been realized this study uses these disclosures to examine the association between unsystematic re turns and the magnitudes of first year lifo tax savings for all nyse firms which adopted or extended their use of lifo during the period 1972 80 subject to data availability 6 the research design employs within group comparisons based on cumulative monthly unsystematic excess returns with appropriate controls for unexpected earnings per formance 7 this design avoids several methodological weaknesses inherent in the previous studies and allows more definitive tests of hypotheses relating investor reactions to the income and cash flow effects of lifo adoptions as reported more fully below results based on lifo adoptions made in 1974 are consistent with a positive association between cumulative excess stock returns and the magnitudes of lifo tax savings 8 the results also provide evidence that changes in systematic risk may accompany lifo adoptions however contrary to previous studies most of the sample firms exhibit downward rather than upward changes in systematic risk section 2 reviews the previous studies of stock price reactions to lifo adoptions and suggests explanations for their results section 3 discusses the alternative approach employed in this study while section 4 describes the test methodologies employed the data and data selection procedures are described in section 5 the results and a discussion are presented in section 6 section 7 offers some conclusions

do equity markets respond to earnings paths we present our investigation of whether the u s equity market responds to the path of earnings information an earnings path consisted of two consecutive quarters of earnings announcements adjusted for expectations and seasonality by using analysts consensus forecasts after controlling for the information content over the period we found that security returns for the two quarter period are affected by the earnings path the path dependent security returns are more evident for smaller firms and the path dependence persists after controlling for firm size and investor anticipation of future earnings surprises

market based empirical research in accounting a review interpretation and extension a decade and a half of the most concerted and ambitious research effort in accounting history is evaluated here it is the search into the relationship between publicly disclosed accounting information and the consequences of the use of this information by the major group of usersequity investors as such consequences are reflected in characteristics of common stocks traded in major exchanges this research effort known as market based accounting research mbar obtained its impetus from major developments in finance theory during the late 1950s and early 1960s these were the portfolio selection theory and its offspring the capital asset pricing model capm and the concept of informationally efficient capital markets ecm subsequent developments in information economics agency theory and optimal incentive signaling models were quickly incorporated into mbar while the impetus to this line of research came from other disciplines accounting was not only a beneficiary but also to a modest extent a benefactor mbar is relevant to the study of capital market efficiency the capm information economics and regulation this contribution distinguishes mbar from most accounting areas whose contributions to other disciplines are negligible in

the impact of replacement cost disclosure on security prices new evidence abstract a number of studies have tested for information content in the asr 190 disclosure by comparing the conditional and unconditional distribution of abnormal security returns around the time of disclosure since no differences were observed it was concluded that asr 190 had no information content the study reported below performs a similar test by estimating the regression function of the conditional distribution of abnormal returns this test procedure controls for the information content in contemporaneous historical cost disclosure and uses a conditioning variable not considered in earlier tests it finds statistically significant stock price effects however because most of the effects appear to precede the official announcement date by several months it is unclear whether stock prices were responding to the leakage of the information content of asr 190 prior to disclosure to private production of information contained in asr 190 or to a variable omitted from the study which happens to be correlated with replacement costs

changes versus levels in earnings as explanatory variables for returns some theoretical considerations this paper considers theoretical aspects of the specification of an earnings variable to explain contemporaneous returns the traditional approach in market based accounting research centers on changes in earnings deflated by beginning of period price as the benchmark explanatory variable for returns the reasons for using this variable appear to follow a three step argument first unexpected earnings determine the theoretically correct concept of the earnings variable second the change in earnings approximates unexpected earnings because current earnings approximate expected earnings i e the random walk hypothesis applies 1 third the beginning of period price deflates the earnings change variable to make it dimensionally consistent with returns 2 while this argument seems overly heuristic we are unaware of a generally acceptable analysis that provides a more compelling argument this lack of rigor has recently become an issue because

the information content of earnings and prices a simultaneous equations approach abstract the price earnings relation can be characterized as a system of simultaneous equations earnings and prices can behave as if they are both endogenously determined because they are jointly affected by information that is difficult to specify explicitly specification tests provide evidence that both earnings changes and price changes are endogenous the price and earnings coefficients increase from ols to joint estimation and under a restrictive set of assumptions provide increasingly similar estimates of the permanent component of earnings the evidence is consistent with the contention that a portion of the single equation bias can be mitigated via joint estimation

the market for equity options in the 1870s the introduction of exchange traded options in 1973 led to explosive growth in the stock options market but put and call options on equity securities have existed for more than a century prior to the listing of option contracts trading was conducted in an order driven over the counter market from 1873 to 1875 quotes for options contracts were published weekly in the commercial and financial chronicle during a period that saw extensive marketing efforts by a number of brokerage firms in this article we examine these quotes to determine why this seemingly sophisticated market existed for only a brief period in financial history in 1973 exchange traded options were introduced and for the first time a central marketplace was available for the trading of standardized option contracts in addition the creation of the options clearing corporation provided an intermediary to all contracts the volume of options traded has exploded during the past twenty three years as has our understanding of the pricing of options and other derivative securities put and call options on equity securities however have been available to american investors for more than a century following the civil war an active market in privileges the term then used for options1 developed in new york city with numerous brokerage firms offering put call and double privilege contracts this market reached the height of its activity in the period from 1873 through 1875 during that time indicative price quotes from a particular broker for options on about a dozen equity securities were generally published every saturday in the commercial and financial chronicle these quotes were placed along with the other financial data for the week including daily high and low stock prices bond prices gold prices money

evidence on the effect of bond covenants and management compensation contracts on the choice of accounting techniques the case of the depreciation switch back abstract provisions of bond indenture agreements and management compensation contracts are examined to derive testable implications concerning management s incentives to choose among alternative accounting techniques the hypotheses are subjected to empirical examination by investigating the voluntary change from accelerated to straight line depreciation for financial reporting purposes only the methodology utilized incorporates an expectations model of accounting earnings in an attempt to separate out of the effects of earnings announcements from accounting change announcements which are often concurrent the evidence from both price and non price data is not consistent with the general hypothesis that bond covenants and management compensation contracts are important determinants of the decision to change depreciation techniques five potential explanations for the results are offered

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

determinants of the corporate decision to capitalize interest abstract until 1974 firms could choose within gaap to capitalize or expense interest costs associated with capital expenditures the predominant practice had been to treat interest as a period expense however in 1974 the securities and exchange commission imposed a moratorium on further adoption of interest capitalization by non regulated firms this study empirically examines economic factors potentially influencing firms decisions to expense or capitalize interest prior to the sec moratorium we hypothesize that the choice may be affected by 1 the existence of management compensation agreements tied to reported earnings 2 debt covenant constraints and 3 the political costs for some firms of reporting higher earnings when compared to the control group our findings are that 1 the frequency of explicit management compensation packages was not greater for the interest capitalization group 2 firms with financial ratios closer to likely debt agreement constraints on dividends interest coverage and leverage tended to elect interest capitalization and 3 other than the largest firms in the politically sensitive petroleum refining industry the larger firms were more likely to capitalize interest

cross sectional association between abnormal returns and firm specific variables abstract abnormal returns market model prediction errors are the subject of many event studies in accounting and finance literature conditional on the event of interest researchers have recently used cross sectional regressions to examine relations between abnormal returns and firm specific variables this paper demostrates that non constant variences and covariances in market model residuals across firms introduced bias in the estimated slope coefficients of the independent variables i e the expected signs of the estimated slope coefficients can be predicted a priori a method is develope to removed the bias in the estimated slope coefficiets and is found to be effective this method explicitly takes the dependence among abnormal returns across firms into account methods that assume abnormal returns across firms to be independent do not control for such bias

on cross sectional analysis in accounting research abstract this paper examines cross sectional analysis procedures common to many market based accounting research papers both the economic and econometric properties of levels and returns studies are discussed topics covered include the relations between the accounting studies and cash flow valuation models the role of expectations of accounting variables deflators spurious inference risk adjustment and its relation to growth size and leverage residual dependence dependence among explanatory variables and the effect of scale differences across firms major conclusions are that market value is the correct deflator in returns studies and that levels and returns studies are economically but not econometrically equivalent

fair value disclosures by bank holding companies abstract this paper examines the value relevance of fair value data disclosed under sfas 107 by banks for 1992 and 1993 collectively the evidence suggests differences between fair and book values of financial instruments are associated with market to book ratios however fair value disclosures for financial instruments other than securities are value relevant only in limited settings in addition only in 1992 are fair value variables associated with market to book ratios after incorporating existing historical cost information further analysis suggests the weaker 1993 results are not necessarily due to increased measurement error in fair value numbers

the relevance of the value relevance literature for financial accounting standard setting another view this paper explains that value relevance research assesses how well accounting amounts reflect information used by equity investors and provides insights into questions of interest to standard setters a primary focus of financial statements is equity investment other uses of financial statement information such as contracting do not diminish the importance of value relevance research value relevance questions can be addressed using extant valuation models value relevance studies address econometric issues that otherwise could limit inferences and can accommodate and be used to study the implications of accounting conservatism r 2001 elsevier science b v all rights reserved jel classification m41 m44 g12

internet downturn finding valuation factors in spring 2000 abstract during spring 2000 the internet stock index declined 45 using a sample of internet firms this paper investigates whether this decline was associated with new disclosures such as earnings analyst forecast revisions and web traffic measures or to a reassessment by investors of pre existing information we find only modest evidence that the decline was associated with new disclosures however returns and post decline stock prices are significantly explained by 1999 annual report data when earnings are decomposed into gross profit and various expenses traditional financial information contributes significantly more in explaining the cross sectional returns and price levels than non financial information

evidence of the impact of mandatory changes in accounting principles on corporate loan agreements abstract the theory in this paper predicts that mandatory changes in accounting princples can affect the measurement rules defined in restrictive covenants in firms lending agreements consequently those mandatory changes can have an impact on the value of a firm s equity even if the changes appear to be merely cosmetic this contracting cost theory is tested by examining of both event related and cross sectional abnormal performance of the equity of a sample of firms when the accounting princples board changes accounting princples for business combinations the theory provides at best in incomplete explanation of the observed abnormal performance

insider trading earnings changes and stock prices this study empirically examines the relation between reportable insider trading and the information captured by annual unexpected earnings for a large sample of firms spanning a ten year period 1978 87 each observation is assigned to one of four groups based on the direction of net insider trading buy sell and the sign of unexpected earnings for each of these groups 15 month cumulative abnormal returns are regressed on annual unexpected earnings the slope coefficient is the largest for the group where insiders are net purchasers and the sign of unexpected earnings is positive this is consistent with an inference that insider buying interactively confirms the favorable information captured by positive unexpected earnings and this interaction reduces the noise in unexpected earnings the result with regard to the unfavorable information captured by the group with insider selling and negative unexpected earnings is similar but less pronounced the analysis also suggests that insider trading conveys information not fully captured by the year s earnings

interest rates and efficiency in medieval wool forward contracts while it is commonly believed that derivative instruments are a recent invention we document the existence of forward contracts for the sale of wool in medieval england around 700 years ago the contracts were generally entered into by english monasteries who frequently sold their wool for up to 20 years in advance to mostly foreign and particularly italian merchants employing a unique source of data collected by hand from the historical records we determine the interest rates implied in these transactions and we also examine the efficiency of the forward and spot markets the calculated interest rates average around 20 in accordance with available information concerning the interest rates used in other types of transactions at that time perhaps surprisingly we also find little evidence of informational inefficiencies in these markets

cross sectional dependence and problems in inference in market based accounting research this paper provides a framework and some empirical evidence to evaluate the seriousness of problems in inference that arise in stockreturn based studies when the data are cross sectionally dependent the study is motivated on the grounds that statistical procedures designed to address such problems are often infeasible and even when they can be implemented they sometimes introduce other more serious difficulties thus researchers have frequently adopted an approach that ignores the cross sectional dependence e g ordinary least squares ols the objective of this paper is to help identify the contexts in which ignoring the dependence would lead to serious misstatement of significance levels cross sectional dependence in stock returns data is likely to exist when at least some of the returns are sampled from common time periods this would be the case in all studies of the reaction of stock prices to a

accounting earnings and top executive compensation abstract this paper investigates the role of accounting earnings in top executive compensation contracts it provides evidence in support of the hypothesis that earnings based incentives help shield executives from market wide factors in stock prices the paper demonstrates that earnings reflect firm specific changes in value but are less sensitive to market wide movements in equity values as a result the inclusion of earnings based performance measures in executive compensation contracts helps shield executives from fluctuations in firm value that are beyond their control the hypothesis is shown to explain cross sectional variation in the use of earnings based incentives

the incremental information content of replacement cost earnings abstract the study explores the incremental explanatory power of replacement cost earnings variables derived from asr 190 data with respect to explaining cross sectional differences in security returns as such the study is a natural extension of previous research including analyses of the effect of security returns of asr 190 data at the time of disclosure investigations of cross sectional relationships between security returns and historical cost earnings and studies of multiple signals the basic finding is that pre holding gain net income provides no incremental explanatory powerm given knowledge of historical cost earnings however the converse does not hold taken together the findings are consistent with the contention that pre holding gain net income is a garbled version of historical cost earnings the basic finding is robust under several extensions of the initial research design the research design incorporates a two stage approach which permits a determination of the incremental explanatory power of collinear variables the findings are in contrast to those of a previous study by easman et al 1979 the nature of the difference in research design inducing the difference is identified potential reasons for the difference in findings are provided

an income strategy approach to the positive theory of accounting standard setting choice abstract this paper is designed to provide additional evidence on the positive theory of accounting policy choice by combining individual accounting principles into firm income strategies these strategies were the dependent variable in a probit analysis where the independent variables were size management compensation industry concentration ratio systematic risk capital intensity and the total debt to total asset ratio the results indicate that four of these factors size management compensation concentration ratio and the total debt to total asset ratio have a significant association with the choice of a firm s income strategy this test provides strong evidence consistent with the positive theory of accounting standard setting choice we also present evidence that smaller firms and or firms in less concentrated industries do not appear to make accounting policy choice decisions that are consistent with this theory

the economic determinants of the market reaction to proposed mandatory accounting changes in the oil and gas industry a cross sectional analysis abstract this paper examines the economic reasons for the observed negative abnormal common stock performance of firms whose reported earnings and stockholders equity were negatively affected by the proposed elimination of full cost accounting in the oil and gas industry four explanations of the market effects of this mandatory accounting change are examined 1 naive investor theory 2 modified naive investor theory 3 contracting cost theory and 4 estimation risk theory these hypotheses are developed in detail and used to generate variables for a cross sectional model which explains observed return behavior the effect of the accounting change on total stockholder s equity the existence of financial contracts denominated in terms of accounting numbers and to a lesser extent firm size are shown to be important explanatory variables the importance of these variables is consistent with both the contracting cost and estimation risk theories
